Community-Supported Brewery Program


Mad Science Brewing Company at Thanksgiving Farms offers a community-supported farm brewery (CSB) program. Our program works great if you are getting frequent growler refills -not only is there a cost savings, but you get access to special events only available to members.  We are accepting sign-ups for our CSB on a continuous basis with no time limit to use your share.


We are located south of Frederick on Route 85 (Buckeystown Pike) and open to the public for retail sales. Our emphasis is on high quality, hand-crafted beer using our own homegrown hops, fruits, and vegetables that are available throughout the growing season at Thanksgiving Farm.


Our CSB Program uses beautiful 1/2-gallon growlers that hold our fresh, hand-crafted beer. The price of the growler, 2 pint glasses, and the Maryland alcohol sales tax (9%) are included in the price of the share. You will be required to clean your growler and return it to the farm for filling. Additional growlers, samples, and kegs are for sale at Thanksgiving Farms on Saturdays and Sundays from 11am - 5pm. Of course, you must be at least 21 years of age to participate and pick-up your shares. 


At Thanksgiving Farm’s market, fresh locally-grown fruits and vegetables, as well as a wide variety of annual and perennial plants and cut flower bouquets are available for purchase to complement your weekly selections.


If interested in the Mad Science Brewing CSB, you can purchase your share using the links below and adding your purchase to the shopping cart. Your commitment and payment allows us to have our beer brewed, kegged, and ready for you to enjoy! Want to pay in person? We accept cash, checks, Visa, Discover, American Express, and MasterCard for payment at the store during our retail hours. Members will also enjoy a 20% discount on Mad Science merchandise and early access to special tappings and events.


The non-refundable fee is $350.00 for the ELEMENTAL (full) share, which entitles you to twenty (20) growler fills and two pint glasses.


The non-refundable fee is $180.00 for the RADIOACTIVE (half) share, which entitles you to ten (10) growler fills and two pint glasses.
