In recent years, brewers have become hyper-focused on innovations pertaining to cold-side hopping in order to emphasize hop flavor and aromatics. Meanwhile, many traditional styles rely exclusively on hot-side hopping techniques to achieve the perfect balance between malt and hops. Achieving such a balance requires a clear understanding of hot-side hop performance. This presentation is designed to help you gain control of and predict outcomes associated with hot-side hopping techniques.

Learning Objectives

  • Gain an improved understanding of hot-side hopping dynamics
  • Understand how to quantify IBUs based on informed assumptions of utilization
  • Learn strategies for scheduling hot-side additions to match desired outcomes (bitterness, flavor, aroma)
  • Build the basis for creating a useful hop calculator for hot-side additions based on desired bitterness in the context of desired flavor and aroma intensity
