Fernson's Family


Derek Fernholz, Owner/Brewer

A Milbank, SD native, Derek Fernholz is passion personified when it comes to brewing. Referred to as the “Walking Encyclopedia of Brewing”, Derek’s path started eight years ago. While visiting a friend in Delaware, Derek experienced his “ah-ha” moment in his brewing journey. Derek got in on a tour at Dogfish Head Brewery, and who was giving the tour? None other than Sam Calagione, founder and owner of Dogfish Head. Sam’s passion for the brewing process and the way he talked about craft beer resonated with Derek. Immediately after the tour, Derek bought Sam Calagione’s book Extreme Brewing, came home, and started brewing. He hasn’t stopped since. Derek is a graduate of South Dakota State University and has a big vision for Fernson Brewing Company: To see Fernson become a bigger family than it is now. His goal is to brew as much beer as the surrounding area will drink. He is also recognized by the BJCP as a certified Beer Judge. Derek and his wife, Hillary, live in Sioux Falls with their newborn daughter Faye and Golden Retriever Alice.


Blake Thompson, Owner/Brewer

Methodical, analytical, and creative, Blake Thompson doesn’t just jump into things. He makes absolutely sure before he does. Blake fell in love with the fermentation process after spending time at Jessup Cellars winery in the Napa Valley. He realized years ago that a huge void exists in the Sioux Falls area: a lack of breweries. Blake became serious about beer after brewing with friends and getting a job at Bitter Esters Brew Pub in Custer, SD after graduating from Augustana College. Blake left the brewery in South Dakota after getting accepted into the Brewing Program at University of California-Davis where his dream continued to grow the more he learned. Upon completion of the Brewing Program, Blake returned to Sioux Falls and began writing a business plan to open his own brewery. Blake also completed a brewing course through the Siebel Institute in Chicago and has been brewing for seven years. Blake and his wife, Kayla, live in Sioux Falls and have a Yorkie, Millie.
