About This Course

This course includes 35+ minutes of video

In this video course, Main & Mill's Denny Foster and Brandon Bischoff explain and demonstrate—using their homebrew-scale pilot kit—their method for parti-gyle brewing. This traditional technique allows you to get two or three different beers out of the same big malt bill. Among other topics, they discuss: 

  • The basics of parti-gyle brewing
  • Practical parti-gyling on a homebrew-scale system
  • Developing recipes for parti-gyle runnings
  • Resources for calculating water adjustments
  • Planning and checking for gravities on separate runnings
  • Avoiding astringency in second runnings
  • Planning for a parti-gyle brew day


The course also includes parti-gale recipes and live demonstration of how they use Beersmith and Bru'n water to dial in recipes.

Instructors

Main & Mill Brewing Company in Festus, Missouri, has earned attention from enthusiasts for their big, rich, full-bodied stouts, such as their Barrel-Aged Imperial Breakfast Stout. Less well known is that they often brew lighter beers for their own pub, based on second runnings from those same huge grists.
