Having read The New IPA, I was swayed and went all in to fermentation dry hopping, like many others. Why compromise your beer for 2-3 weeks if this can be avoided altogether? Personal Hopping Experience Yes, the burn goes away after a few weeks, but sometimes some of the perceived harshness remains in the beer. Anytime I use a very high alpha hop like Galaxy above 65F, the hop burn resulting from the use is very strong. I have certainly experienced this first-hand when dry hopping at high krausen or during fermentation at all. When dry hopping at 66☏ (19☌) compared to 39☏ (4☌), there was an increase in polyphenol concentrations of nearly two-fold for the low-alpha hop and nearly 2.5-fold for the high alpha hop the temperature of the dry hop significantly increased polyphenol extraction. There, he covers multiple aspects of cool dry hopping and how cooler and shorter dry hops lead to less hop creep and help prevent polyphenol extraction (hop burn). As it turns out, Scott Janish has a very interesting article supporting multiple points from this article in his recent piece titled "A Case for Short and Cool Dry Hopping. One of the thing I had to learn the hard way is what hop burn is. YCH Webinar on Hop Survivables can be found here. I've personally been a big fan of dry hopping with Mosaic and Sabro in mid-to-late fermentation, and these, as well as Idaho 7, are all fantastic in Whirlpool as well. You'll find these on the right side of the chart, while hops with highest amounts of "survivable" compounds are more toward the left side of the chart. ![]() Many of these hop compounds bind to proteins and yeast cells, and in turn drop out at the end of fermentation. I won't get into the specifics of the study as YCH and Scott Janish do a much better job than I ever could, but I would like to point out that not all hops have the compounds that can survive fermentation. Moving on to another piece from the YCH webinars, is a graphic demonstrating the amount of specific hop pounds, and the amount of each, present within different hops. It's insightful and has interesting tips from the kind folks at YCH. For the full details on this study, I recommend watching the webinar linked above. In case of Geraniol, these values are over two times larger.Ĭoncluding this study, it's evident that the ppb values of the post-fermentation dry hop beer far exceeded the Active fermentation beer. PFDH - Post fermentation values for Final Beer Linaloon and Geraniol are noticably larger than AFDH values. WP Only (Whirlpool) - values are the lowest throughout.ĪFDH - Active fermentation values are much higher than whirlpool addition only. Specifically, the Final Beer values of various compounds demonstrate the effect various hopping methods have. Comparison of three beers, one with whirlpool hops only, one hopped during, and one after fermentation.īeyond the flavor intensity noted in each beer by the sensory panel (graph), observe the final ppb (parts per billion) in the table above. This graphic was part of a webinar by Yakima Chief Hops on Dry Hopping Techniques. So far, it looks like almost all of them dry hop post-fermentation. There are other breweries that ferment at lower temperatures, these are just the specific ones that mentioned their dry hopping schedule on the podcast. ![]()
