We are a veteran-run farm brewery specializing in high quality hand-crafted beer, founded on January 2nd, 2013. We produce ales and lagers using traditional styles as a guideline and tweaking them to match our tastebuds.


We received our Brewer's Notice from the Alcohol, Tax, and Trade Bureau (TTB) on June 2, 2014. We applied for our Accessory Use Determination from Frederick County for our farm brewery in accordance with the new zoning text amendment in February 2015. We submitted our amended state license application on February 9th and were approved on March 11, 2015. We have been open since April 11, 2015 and are now the 7th oldest brewery in Frederick County!


We are the first Southern Frederick County, MD farm brewery and are located at Thanksgiving Farms in Adamstown, MD. As a farm brewery use our own homegrown hops, fruits, vegetables, and other products from the farm in every batch of beer brewed. 


Currently we are growing Columbus/Zeus, Nugget, Comet, Galena, Chinook, Cascade, and Magnum hops. We have over 200 hop plants in our field so we will have plenty of hops for years to come.


We also are offering membership into our Community-Supported Brewery  (CSB) program! We look forward to serving you and being part of your extended family.



I'm Brian! Mad Science Brewing Company is my brainchild and I'm happy to share it with you! I hail from Big Sky Country (Montana, if you didn't know) and have been in Maryland for almost 30 years now. My wife, Louisa, kept telling me I should get a hobby. Well, after 6 years of walking past the homebrew competition bottles at the Great Frederick Fair, I decided I'd pick up homebrewing as my hobby. Ten years later, here I am working to make it a grander scale and for a lot more people! 


What's with the name you ask? Well, I'm actually a scientist! I have a Master's of Science degree from Hood College in Biomedical Sciences and work with small and medium biotech companies to make vaccines, drugs, therapeutics, and medical devices. I have worked with some of the most dangerous viruses on the planet while enlisted in the Army at USAMRIID and enjoyed every minute of it! Hence, the mad takes a special kind of person to work with those things.


I enjoy hops; nay, I LOVE HOPS!!!  I am a hop head! Period. No discussion needed. As such, most of the homebrew I've made tends toward a more hop-forward balance. Don't get me wrong, I love my malts too. But, hops. Hops are special. They have aromas that make you think of fruits, citrus, grapefruit, lychee, pine, resins, pears, etc. I started growing my own at home and now have expanded to 80+ hops at Thanksgiving Farms. I grow Columbus and Zeus (they're related), Nugget, Comet, Galena, Chinook, Magnum, and Cascade. These are straight up American hops, born and bred here in the U.S.  I can't wait to see how well it grows and using it in our beers.


Welcome to our family and I hope you enjoy the experiences, smells, and flavors that we will be throwing your way.
