Jason Johnson has been homebrewing since 2000 and a ranked judge with the BJCP since 2005. He currently holds the rank of National Judge. Jason was the Co-founder and Co-Host of Brewnology: The Podcast where they explored all avenues of Beer Judging for their listeners. Although the show had a good 2 year run, they ran out of judging content at 50 shows and had to call it quits. Past episodes of Brewnology can still be found on YouTube. Jason is also the author of an e-book titled Roasted: A Homebrewer's Guide to Homeroasting Grain.

Although currently an independent homebrewer no longer active in a local club, Jason was a member of the Manty Malter's homebrew club in, Wisconsin. Jason has held several officer positions within the club including president as well as lead the club's judging education program. He also has a set of free BJCP Prep classes on YouTube to help judges who may not have a nearby club to supplement their self-study. He also helps these people by answering questions via messages. So far the course has been fairly popular and helped some judges in other countries study for their exams.

As a brewer, Jason mostly likes to brew traditional classic styles. He brews a lot of American ales (America Pale Ales, American IPA, and American Pre-Prohibition Lager). Other styles he likes to brew are Chocolate Oatmeal Stout, Belgian Wit, Saison, Dubbel, and Cream Ale to name a few. As far as craft beer goes, he enjoys tasting and Judging the full gambit of the beer spectrum.
