This past weekend the team took a trip out to the Renaissance Festival (known to the public as Ren Fest) in Todd Mission, TX to learn about 17th century beer brewing. It was my first time at Ren Fest, and my first time seeing brewing in process. I didn’t have any expectations coming on this trip, but when I saw festival attendees in crazy costumes I could only assume this was going to be quite a unique experience.  

Our team arrived bright and early to Brigadoon Brewery where the brewmaster, Alan Ward, explained the basics of the brewing process. The recipe, derived from Sir William Harrison’s Description of Elizabethan England, was only a few steps but took the entire day to brew!

In addition to the length of the brewing process, we were unaware of the amount of science behind it. The temperature, sugar levels, how the grains were milled, and many more aspects had to be carefully controlled and monitored to ensure the brewing went smoothly. Sarah Bankhead noted, “After spending much time reading historical accounts and methods for brewing, it was very neat to get to see and experience the process come to life.” Nicki Fischer added, “It is one thing to read about the recipe and the methods used to brew the beer, and it’s another to sit first row and lend a helping hand.”As scientists, I think it’s safe to say brewing is not only a craft but an intense scientific procedure as well.

In the midst of the brewing, our team also promoted our historical beer tasting event by asking bystanders to enter their contact information on a slip (to be notified of the event) for the chance to win tickets to our Elissa shipboard tasting on March 23, 2018. We jokingly called this “heckling,” and dressed up in bacon and egg costumes, our team members took turns as pairs advertising for the event. Our microbiologist, Dr. Elizabeth Latham, a master heckler, taught us how to draw people into  conservation and keep them interested. I can speak for the team in saying that we all got out of our shell during heckling!

What did the beer taste like? I can’t say as 1) about half of us, including myself, are underage and were given a wristband that indicated we could not try any alcohol, and 2) our beer is not ready yet as it has to go through fermentation for the next 2 weeks. We will be picking the beer up on Thanksgiving weekend!

The trip was a great experience in learning the science of brewing beer and how important it was to 17th-century sailors.  A big thank you to Alan and his team who were extremely helpful with keeping the recipe as historically accurate as possible. We couldn’t have completed the brewing project without the generous help of Brigadoon Brewery & Brew School. 

A little about Brigadoon Brewery & Brew School…

 

Brigadoon Brewery & Brew School LLC

Mission:

To educate as many minds and palates as possible about the important role of beer in the development of civilization and the qualities and attributes of craft beer. In short:

“We believe that life is too short to drink bad beer.”

2017 will be our 10th season at the Texas Renaissance Festival

About:

Brigadoon Brewery & Brew School is a unique brewpub and teaching facility located on the grounds of the Texas Renaissance Festival in Todd Mission (Plantersville), Texas. Brigadoon Brewery and Brew School was born from a desire to bring our love of brewing beer and our love of the Texas Renaissance Festival together. We opened in the fall of 2008 as a unique living history demonstration booth brewing with historical equipment and techniques.  In 2011 we expanded production to include a modern stainless system off stage. Both the historical and modern brewed beer are sold back to the public. To our knowledge we are the only renaissance style brewery or brewpub operating on the grounds of a Renaissance Festival using period specific recipes, equipment, and methods as well as modern equipment to brew hand crafted ale and serve it to the public.

What does that actually mean? Well, nine weekends a year (a total of 19 days) we don our garb and brew beer using equipment, ingredients, techniques, and recipes that would have been available during the 1400s through the 1600s. We then give samples of ale away and sell pints to visitors that pass through our booth allowing them the opportunity to taste a piece of living history.

Brigadoon Brewery Currently brews over 12 different beers.  Brigadoon’s Scottish and English Ales are both reverse engineered from tax records to match a period in history (1490-1550) and are brewed on period equipment using period techniques and then sold back to the public making each sip a taste of history.

Poster Season Came Early This Year https://nauticalarch.org/poster-season-came-early-this-year/ Fri, 27 Oct 2017 14:58:25 +0000 https://nauticalarch.org/?p=18066 By Melissa Dossett

Our team was super excited to get right back to work on our cod and beef research this year! We met (some for the first time) with bright and shiny faces, ready for anything that might come our way. Including…having two posters ready in under a month! While team members such as myself and a few others were not too worried about this, it was a different story for the rest of the team. Most of them are freshmen or sophomores who have never participated in a formal research conference before, and/or it was their first semester with the team. Thus, a senior team member and I were put in charge of the Cod team, and another experienced member was put in charge of the Beef team. Due to the fast approaching deadline, it felt a little like: “Ok, we need two posters: Cod team, Beef team, GO”. Luckily though, our team has amazing mentors that supported us through this experience. Nonetheless, we were ready and willing to take on the challenge. Our team really rallied and got so much done in so little time. I only participated in my first conference last semester, so I was worried about coordinating a team so soon, but luckily, I had a great team to work with. I also think that by being thrown into this so fast, our team learned how to work well together in a short amount of time.

We ended up getting both posters done in the nick of time, and they were awesome! Then, came my personal favorite part–presenting. I get really excited to share with people things that I have worked hard on and I could tell my team members were excited too. I presented the Cod poster with Daniela Trevino, Emily Bandy, and Somer Smith. This group of girls in particular really complimented each other well, as each knew certain aspects about the research that maybe another wasn’t as clear on. When asked about her first conference experience at A&M, and with the team, Emily said, “I had a great experience presenting our data on salted cod. Seeing the research with everyone’s poster there made me really excited for all the things we can do with our research!” Additionally, Somer stated that, “Having the opportunity to present a research poster with my peers was amazing! I was able to tell others about our project and learn about all of the other projects being conducted at A&M.” Echoing what Somer mentioned about learning about the other projects, this is something I really enjoyed as well! We were placed next to a group who’s poster we were really interested in, and vice versa.

I think experiences like these are what really brings our team together and reminds us why we were passionate about joining the team. It also shows that together, we are able to accomplish tasks that may seem daunting!

Crowdfunding Nautical Archaeology https://nauticalarch.org/crowdfunding-nautical-archaeology/ Wed, 04 Oct 2017 13:15:41 +0000 https://nauticalarch.org/?p=16191 The Ship Biscuit & Salted Beef Project is currently crowdsourcing research funds to continue the nutritional and microbiological testing of their shipboard food items. Over the summer, the majority of food items were made according to 17th-century historical documents and data from archaeological remains and placed on Elissa, the 1877 tallship docked in Galveston. Upon initial testing, a surprising number of microbes, both in diversity and quantity, were present on the food, despite the great amount of salt and other bio-preservatives used in their making, causing the team to exhaust their laboratory supplies much sooner than expected. Microbiological analysis is time-dependent, so having the proper amount of supplies shipped in and ready is critical to have sound data. If you’re interested in donating, please check the crowdfunding website here.

About This Project
Were sailors actually ship-shape–or were they truly a sickly bunch? Find out with us! We are replicating shipboard food using exact ingredients and methods from the 17th century. Then, a transatlantic voyage is simulated by storing the food in casks and keeping them on Elissa, the 19th century tallship. The nutritional and microbiological data from this project will offer a glimpse into the unique food situation, health, and daily life of past sailors.

What is the context of this research?
“[Unsalted food] is rotten and stinking [so] it is necessary to lose your senses of taste and smell and sight just to [consume] it and not sense it,” wrote Eugenio de Salazar, a Spanish explorer to the New World, in 1573. Before canning technologies or refrigeration were invented, food was fermented, salted, or dried to prevent spoilage. Unfortunately, these methods of preservation also decrease the nutritional value of food on lengthy voyages. Previous attempts to gauge the nutritional value of shipboard diets were based on historical documentation or existing USDA nutrition charts that only reflect nutritional values from modern foods, not historical ones.

What is the significance of this project?
This project hopes to understand the effects of shipboard diet on the health of sailors by determining the nutritional and microbial intake of seamen on 17th-century English ships by replicating the food items as close to possible as they were in the past.

This project will give us great insight into humankind’s shared maritime history and answer some longstanding questions in archaeology and history. We hope to understand how this unique subset of society ate and how this impacted their health, as prior to airplanes, all immigrants who made the transatlantic voyage to the United States came here via ship. Yet, there is little knowledge on the precise conditions of the food 17th-century sailors consumed.

What are the goals of the project?
In this project, shipboard food will be replicated using the exact ingredients and methods of preparation from the 17th century, including non-GMO ingredients, the exact species of plant or animal, and the same butchery methods and cuts of meat. Archaeological and historical data will be used to replicate the salted pork and beef, ship biscuit, wine and beer, and other provisions aboard Warwick, an English race-built galleon that sank in 1619. We will also simulate a trans-Atlantic voyage by storing the food in casks and keeping these in a ship’s hull for three months. Representative samples of food will be sent for nutritional and microbial analysis, including species of microbes, their quantities, and toxins, to understand changes that the food undergoes.

First Look at a Rare Northern Steamboat https://nauticalarch.org/first-look-at-a-rare-northern-steamboat/ Wed, 27 Sep 2017 22:03:51 +0000 https://nauticalarch.org/?p=15714
Heritage steamboat Nenana at Pioneer Park, Fairbanks, Alaska  (J. Pollack 2017)

 

Research Associate John Pollack has just returned from Alaska where with the assistance of City of Fairbanks staff a hull assessment was conducted of the heritage ship Nenana. The 210’ Nenana was one of the last and largest American-built stern-wheel steamboats to work on the lower Yukon and Tanana Rivers, where it served as a packet carrying up to 52 passengers and towing 6 barges at a time. The standard two-week route was a 1600 mile round trip to Marshall, with the occasional trip above the Arctic Circle to Fort Yukon. Nenana is the only known example of a northern wooden-hulled  sternwheeler designed by naval architect W.C. Wickum in 1932 and built from blueprints. The goal was to create a powerful, minimum draft tow boat suitable for the shallow, lower sections of the Yukon River drainage. The ship has a barge-like hull with standard chine construction, a rectangular cross-section amidships and a broad bow. The blocky hull is visibly less sophisticated than the streamlined Klondike 2 which carried freight cargo on the main deck, and towed only a single barge through the more constricted and meandering sections of the upper Yukon drainage. Another significant difference from Klondike 2, was the use of very few water-tight bulkheads on Nenana.

 

 
A snag deflector arc in front of one of the four main rudders (J. Pollack 2017)

 

Several rare examples of hull architecture and machinery were documented, including novel snag deflector arcs designed to keep debris away from the four main rudders, an uncommon slaved tiller assembly placed just inches above the main deck, and the largest number of large transverse beams yet found in a Yukon River steamer. Nenana also contained the second known example of an internal hog post and chain system installed below the main deck, and used to correct hull weakness (e.g. hogging) in the original design. Additionally, the team discovered a truly unique and baffling framing method at the stern rake (or apron), where an upper set of floors (complete with limber holes) was installed above the centerline and side keelsons, which in turn rests upon the lower floors to which the hull planking is spiked. These elevated floors are not shown in the blueprints, suggesting they were an “on-the-fly” alternation made by the shipwrights when the prefabricated hull was assembled in Nenana, Alaska.

 

Largest shipwreck at the Golden site

 

In late September, three additional small stern-wheel steamboat sites were confirmed on the Upper Columbia River between Fairmont and Golden BC, by Danish-Canadian archaeologist Xenius Nielsen and Research Associate John Pollack. The Fairmont site lies a kilometer north of the source of the Columbia River at a point where the river is less than 15 m wide. The Golden sites are 100 km further north (downriver), and plans are being made to document the largest of the three during low water in the spring of 2018. Note the fresh grizzly bear tracks in the mud.

Eight New Shipwrecks Discovered in Greece’s Fourni Archipelago https://nauticalarch.org/eight-new-shipwrecks-fourni/ Mon, 31 Jul 2017 16:21:22 +0000 http://nauticalarch.org/?p=11388  
Left: An archaeologist systematically photographs a wreck site to create a 3D site plan; Right: High resolution 3D model of a Roman period shipwreck

The 2017 season of the Fourni Underwater Survey in Greece fully documented 14 sites located during previous seasons. While the focus of this season was the thorough documentation of sites located during the 2015-2016 seasons, the survey of shipwrecks in the small archipelago led to the discovery of eight new sites, for a total of 53 shipwrecks located over three seasons.

The fieldwork was conducted during three weeks in June by the Ephorate of Underwater Antiquities/Hellenic Ministry of Culture and Sports in cooperation with RPM Nautical Foundation. The research vessel Hercules conducted seafloor mapping using multibeam sonar and inspected deepwater targets with an ROV, while diver teams conducted photogrammetry, drawings, and recovered key artifacts for further study and scientific analysis. The ROV and divers occasionally worked in tandem to record and recover artifacts from sites. Amphoras from each wreck were raised for conservation, archiving, and 3D modeling, and a few were prepared for DNA and residue analysis, as well as testing a new method of direct dating of ancient ceramics.

The eight new sites span the Classical Period through the 19th century A.D. The majority date to the Late Roman period, but the most significant wrecks include a Classical shipwreck carrying amphoras from Chios and a Roman shipwreck transporting Dressel 28 amphoras from Iberia. The project also found a wide range of anchors dating from the Archaic Period through the Byzantine Period. The finds further illuminate maritime connectivity between the entirety of the Mediterranean and reveal trade and technological changes throughout history.

We are very grape-ful… https://nauticalarch.org/we-are-very-grape-ful/ Sun, 23 Jul 2017 03:46:08 +0000 http://nauticalarch.org/?p=11368  

By Erika Davila

Last weekend we went on a mission in the name of science– we took on a great opportunity last minute thanks to Dr. Justin Scheiner in Texas A&M’s Department of Horticulture, and found ourselves harvesting grapes at Mound Prairie Vineyard in Snook, Texas! The owner graciously allowed us to take grapes from two rows that were left over after their harvest which he did not need. Conveniently, we were looking to create our own wine for the project, so obviously it was destined for us!

Harvesting grapes. From left to right: Rogelio Casas, Erika Davila, and Sarah Bankhead

We came across a few friendly, and not so friendly, little critters that call this vineyard home. Unfortunately, a hornet stung the fingers of two of our group members, but hopefully the risk was well worth the reward!

Over the course of several hours we collected about 100 pounds of grapes, which equates to a little over 6 gallons of wine! YAY! To make it as similar as possible to 17th-century wine, we used two common methods of preparation. The first 5 gallons were made using a press, which uses a machine to crush the grapes (in our case a modern bladder press from the Horticulture department), and put in a 5-gallon oak barrel. Another gallon of wine was made by stomping on the grapes, which proved to be a fun workout experience! Both of these methods crush the grapes and release the juice that contains the sugars necessary for the microbes on the grapes to begin fermentation. Now we play the waiting game!

Thanks again to the grape group of people that helped out!

Check out our winemaking process in this fun video below!

Fun fact of the day: The Multicolored Asian Lady Beetle (Harmonia axyridis), a common grape pest, can sometimes be crushed with the grapes during the wine-making process, and taint the flavor of the wine due to the alkaloids found in their defensive secretions. Read more about them here:

Exciting Collaborations https://nauticalarch.org/exciting-collaborations/ Fri, 21 Jul 2017 04:14:12 +0000 http://nauticalarch.org/?p=11348 By Michael Pawlus

In an effort to obtain the best possible outcome for our test brew, the team has begun initial talks with Karbach Brewing Company in Houston.

Karbach Brewing, founded in 2011, has a proven track record of brewing success and will be assisting our efforts by brewing a modern variation of the selected recipe and hosting a fundraiser, featuring the tribute beer, at the recently renovated brewery in Houston.   The knowledge possessed by the staff at Karbach as well as the capacity and willingness to assist with such an interesting project will help spread the outcomes of the project and raise awareness of other projects going on as well. Some of the team made the trip from College Station to meet up with Brand Manager David Graham and Brew Master, Eric Warner to tour the facility and lay out a plan for execution.

Meanwhile, we have been in touch with Nathan Barkman, the owner of Rio Brazos Distillery, who has been so kind to donate a few casks for both the project and the two exhibits planned in Houston. Rio Brazos Distillery specializes in using locally sourced grains and simple, small-batch, pot-distillation for making premium whiskeys and bourbon. The SBSB team is also considering making some 17th-century distillates with Mr. Barkman to get our hands dirty and explore how aqua vitae was made in the past.

 

Last but not least, Karyn and Calvin Medders at Chubby Dog Farm will be helping us prepare the salted beef and salted pork for our project.

Chubby Dog Farm specializes in heritage mangalitsa-red wattle pigs on wooded acres and GMO-free feed and no antibiotics or hormones ever. Take a look at their lovely farm here!

Thanks to all of our wonderful collaborators and sponsors without whom this project would not be possible.

Lab Work and Sampling Precision! https://nauticalarch.org/lab-work-and-sampling-precision/ Fri, 14 Jul 2017 03:46:18 +0000 http://nauticalarch.org/?p=11356 By Karen Galvan

We have made small breakthroughs in the lab as well as in solidifying our project procedures.  In the lab, we have finally discovered the possible causes of previous inconclusive results!

We suspect that the gel electrophoresis results were not showing up as expected because the water we used to prepare the samples was exposed to too much human DNAse, so we have changed our DNA extraction method to a simple microwave after confirming its effectiveness, and also adjusted the annealing temperature of the thermocycler for Polymerase Chain Reaction. In short, we are on our way to knowing what mysterious microbe was growing in the salted beef made last Fall.

Of course, none of the lab efforts matter without proper execution of the experiment. The team has been meeting weekly and discussing our ideas for how to retrieve and store the individual food samples in the most controlled fashion to retain as much consistency as possible and reduce contamination of the food remains. We will be preparing salted beef, pork, and cod, oatmeal, peas, ship biscuits, and beer. We plan on collecting 3 samples per food item regularly: 2 that are raw for microbial testing and the other that will be cooked and used for microbial and nutritional testing. For now, we are individually designing specific collection protocols for the each food item, and coming up with a proper way to store all of the samples for the car ride back to College Station, TX given it is approximately a 2 to 3 hour drive back. We are also coming up with important variables to monitor and record. For example, we will be recording the temperature, pH, and volume level of the brine in the barrels, and noting the color of the foods as soon as they come out of the casks.

One of the most crucial aspects to control is retrieving samples without exposing the food to stray microbes. One of the team members, Rogelio Casas, has been designing an integrated sensor pump that will allow us to execute the aforementioned. The lab team members are currently reviewing research on which microbes we expect to find in the salted beef and pork so that we can have an idea of what to expect once the project launches and in which kind of media to grow the bacteria given their unusual environment.

Stay tuned to hear our progress on both our wine-making experiment and environmental sensor in the next few posts!

Laboratory Research Update: What’s that microbe? https://nauticalarch.org/laboratory-research-update-whats-that-microbe/ Fri, 09 Jun 2017 00:42:05 +0000 http://nauticalarch.org/?p=11275 By Melissa Dossett & Monica Montgomery

Over the past few weeks, we have started working in the lab to go beyond the book-learning aspect of our research and delve further into the hands-on aspect of it. We were unsure about what to expect at first, as the labs we have done up until this point have been with TAs and professors carefully guiding us through the procedures and techniques. With the help of each other, Somer Smith (another undergraduate student), and the guidance of Elizabeth Latham, lab time has become very exciting because we have to think for ourselves and design research experiments.

What’s that growing on the plate? We’ll report as soon as we find out!

To begin our work in the laboratory, we plated different bacterial cultures that were growing on the moldy meat samples we had. It was not too pleasant of a sight, but it was fascinating to see the rapid growths of mold within the container! Next, we worked with a Qiagen DNA extraction kit which consisted of a great deal of centrifuging and pipetting. This step allowed us to isolate bacteria within the collected samples for further purification. PCR (Polymerase Chain reaction) was performed next. This process is used to amplify a small amount of DNA. We later attempted to utilize what we had obtained from the PCR to do a gel electrophoresis. Gel electrophoresis is a method used to separate mixtures of DNA or proteins according to molecular size. The molecules are separated by being pushed by an electrical field through a gel that contains small pores. The results from the gel electrophoresis were unsuccessful and could have been caused by one of three problems: 1) we did not get enough DNA amplification during PCR, 2) there was no DNA to begin with, or 3) there was improper pouring of the TAE buffer causing the ladder to contaminate other wells. Currently, we are still working to correct and troubleshoot problems for the gel electrophoresis.

Before summer break, the last experiment we left off on was using the DNA spectrophotometer to test for DNA purity within our samples. Unfortunately, the spectrophotometer results showed that our samples of DNA were impure. To fix this problem, we are going to fix errors in the plating and DNA extraction methods. There could possibly be cross contamination and incorrect handling of substances that we’ll get to the root in the next few days.

For the future, we are planning to perform tests on retrieved food samples from Elissa. Soon we will be designing experimental procedures for food collection and testing. We will further identify microbes, toxins, and their respective amounts in the lab and carry out a chemical analysis of suspected factors that may possibly be affecting the food. We will compile this data with our nutritional research to fully understand the nutrition and microbial intake of the average sailor from the beginning to end of a 3-month voyage. In addition, we will test promising microbes for medical and other beneficial uses. Given the unique preparation and storage of the food, we hope to discover probiotics that can improve people’s health today.

After troubleshooting errors within our previous experiments, we are looking forward to this next phase of research, as we are about to dive into our new laboratory objectives and hopefully discover the unknown!
