Hop And Brew School Ep10 | Hop Life Cycle Apr 20, 2019

Show notes

In this episode of the Hop And Brew School® Podcast, Justin Crossley and Nick Zeigler are joined by the infamous Jason Perrault from Yakima Chief Ranches. Jason and his team at their family farm are responsible for helping to bring many of the most famous and popular hops to market over the years, including brands such as Simcoe®, Mosaic®, Warrior®, Ekuanot®, and more! To help us learn about the life cycle of hops, Jason walks us through what factors hop breeders must take into account and grapple with when developing new hop strains. Things like yield, pest resistance, and even the varying harvest windows of select strains, only begin to scratch the surface during the long life cycle of a new hop being brought to market. Jason dives further into some of the specific varieties that have passed through his program throughout the years, and even gives us a glimpse of what we might expect to see in the future. This episode is a brewers dream if you're looking to understand more about the agricultural lifecycle of your brewing ingredients and how much science, creativity and sheer effort goes into getting them to you.

Hop And Brew School Ep9 | Water Chemistry And Hops Apr 05, 2019

Show notes

In this episode of the Hop and Brew School® Podcast, Nick Zeigler and Justin Crossley discuss how water chemistry affects hop utilization, bitterness and aroma with our good friend John Palmer, author of How To Brew and Water: A Comprehensive Guide For Brewers. We dive into how pH affects flavor expression on the palette as well as how sulfates and chlorides hale express different flavors in beer. We also cover many of the factors that affect bitterness, including isohumulones, humulinones, hulupones and hop polyphenols. John helps us put it altogether with a discussion on how time and temperature play a heavy role in getting the characters we are looking for in our beers.

In this episode of the Hop And Brew School® Podcast, Nick Zeigler and Justin Crossley discuss the mysterious phenomenon of "hop creep", where brewers experience changes in specific gravity, among other things, when dry hopping their beers. Nick walks us through what is happening in solution to cause the "hop creep" effect, including the chemistry behind it. And of course, what would a Hop And Brew School Podcast be without lessons in how to account for it, or even prevent it.

Hop And Brew School Ep6 | Hop Oil Fractions Feb 23, 2019

Show notes

In this episode of The Hop And Brew School Podcast, Yakima Chief Hops Technical Manager, Pat Jensen, is back on the show, along with Technical Brewer, Tommy Yankon.

Hop And Brew School Ep4: Good, Bad And Ugly Jan 25, 2019

Show notes

In this episode of the Hop And Brew School Podcast, Nick Zeigler and homebrew superstar, Nathan Smith, walk us through off flavors in beer that can be derived from hops and their use. The three main categories of such flavors can be described as undesirable flavors (such as sulfurous, vegetal or cheesy), excessive presence of flavors (such as grassy, lingering bitterness, or astringency), and a lack of character of flavors (such as bitterness and aroma). The team goes over each of these categories in detail to help brewers understand where they might be coming from and provides some techniques to troubleshoot major issues.
