87: Modist Brewing’s Keigan Knee: Brewing Otherwise Impossible Beers Using a Mash Filter

Explicit content warning

06/14/19 • 54 min

Mash filters are common in commercial brewing—most large-scale commercial breweries use them—but they’re far, far less common in craft brewing. While most breweries use them to maximize efficiency, Modist Brewing (Minneapolis, Minnesota) cofounder and head brewer Keigan Knee has pushed in a different direction, using them to produce IPAs with no barley (only wheat and oats) or pushing the percentage limits on alternate grains like spelt. The result is unique-tasting beers that surprise and delight. In this episode, Knee discusses the mash filter process and unique design considerations, the finer points of malt in designing hoppy beers, layering cryo and T-90 hops of the same variety on top of each other for heightened effect, locking in flavors using cryo hops on the hot side, designing fruited beers to finish at the same gravities as that fruit, and wood prep processes for foeder-aged lagers.
