Happy Halloween from the ID team! This week we’re chatting about a popular halloweekend beverage: Beer and a “creepy” phenomenon seen in a west coast favorite, IPAs. Hop creep may not mean that there are creepy crawlies in your beer, but it may lead to exploding cans or a beer that’s all trick and no treat. To find out more, we are talking with Cade Jobe on his work on hops maturity and its impact on understanding this spooky problem facing the beer industry.
Cade is a 1st year masters student in the Department of Food Science and Technology at OSU, where he works under the advisement of Dr. Tom Shellhammer. In the “Beer”, or “Hops”, lab there are a wide variety of projects on the various components of beer, in addition to offering resources to the brewing industry by running standard analytical measurements on hops. Cade moved to Oregon in pursuit of joining the Hop Lab, after falling in love with home-brewing and embarking upon a career shift from law to food science. While his master’s work is going to be more focused on the impact of wildfire-smoke on hops, his post-baccalaureate work focused on hop maturity, in particular the Citra hop variety.
How does one study the impact of hop maturity? Cade worked with a hop grower in Yakima, Washington to harvest hops from 3 fields at 7 different time points during the hop picking season. These dried samples were then sent back to Corvallis where they underwent standard hop chemical analysis, sensory analysis, and enzymatic analysis.
This is all great, but how does it help me drink beer? From the chemical analysis, there are standard components that are measured to give an overall hop quality measure to know if it is going to produce the desired result. From sensory analysis, they can see what aromas are associated with the different maturity levels of the hops and what aromas they would impart in beer. Spoiler: late season hops might identify if you are a vampire! And finally, going back to the exploding beer cans, the enzymatic analysis shows the potential of hop creep occurring so that brewers can mitigate the problem.
