High Gravity: Pro Techniques for Homebrewers

This seminar takes a deep dive into the world of high-gravity brewing, beginning with an explanation of the science and following through with detailed explorations of technique, recipe design, and equipment choice. Topics include changes in mashing, sparging, and lautering; the use of adjuncts; yeast stress, nutrients, starters, and alcohol tolerance; and more. Acquired in formal brewing education, this information has been filtered through practical application in both professional and homebrewing experiences. Viewers will leave with a better understanding of the science and process, as well as direct, actionable techniques for creating great high-gravity brews.

Learning Objectives

  • Understand high gravity and its impact on the brewing process and recipe design
  • Walk away with professional techniques that can be directly applied to homebrewing and recipe design for high-gravity brews
  • Understand yeast stress, nutrients, ethanol tolerance, and the need for sufficient oxygen;
  • Learn how to adjust the mash and/or sparge for higher gravity results
  • Discuss brewing with adjuncts and/or adding adjuncts to the fermenter
  • Know how to achieve high gravity through double mashing
  • Learn how to manipulate the gravity by oversizing the lauter tun, decreasing the batch size
