I took a break from mentally traveling back through yesteryear for Part 2 of my 2014 retrospective when I came across some rather intriguing news about Sierra Nevada and a certain hop hunting IPA. While most have focused on the now defunct lawsuit from Lagunitas over font and typography, there is an intriguing beer buried in the controversy. Now, SN is known for playing around with hops. They were the first to use wet hops long ago and you need look no further than the recently released Harvest Wild Hop IPA with Neomexicallious, a hop found growing in the wilds of New Mexico. For these hop dynamos, the announcement of a new IPA should come as no surprise, but the process in making this beer does.
The intrigue comes in the form of a Sierra Nevada engineered procedure that allows for the wet hopping of beer year round…in a way. Sierra Nevada Bill (Bill Manly, Product Development Manager for SN – seen below being told his beer isn’t for drinking) states the science thusly in a Beer Advocate forum reply:
“Typically, extracts are made from dried hops using a Supercritical CO2 extraction method, then after the pure hydrocarbon is removed from the hops, one of two things happens: The oil is either chemically adjusted and manipulated into kettle bittering products or used as aroma (downstream or cold-side) products–more common in craft brewing. Most commercial extracts are fractionated (refined) in polarized column stills to pull out specific flavor components and highlight some others… We’re literally using wet hops (undried) and using pure steam (hot water) to pull out the essential oils.”
While that is very important and sciencey brewer information, what is it that we, the drinkers of science, need to know? Essentially, SN has come up with a process to steam the oils from wet hops, which are only available twice a year (roughly September and March), and then separate those oils from the residual water. They anticipate that keeping the oil at the proper cold temperatures will maintain the stability and allow them to use it throughout the year. In fact, SN is adding Hop Hunter as a year round release, the first time a new addition has been made to their yearly lineup since 2009.
You may wonder, how is this different from hop extracts which already exist? Well you inquisitive and informed beer drinker, unlike extracts taken from kilned (dried) hops which are chemically altered, this steamed process takes only the pure oils, which provide that awesome hop aroma, and doesn’t include any resins (alpha/beta acids). The lack of acids means this extract doesn’t add bitterness to the beer, just the pure, aromatic wet hop goodness.
Hop Hunter’s space-aged oil of the future, which is added to the fermenter, was derived from Centennial, Cascade, and CTZ (Columbus/Tomahawk/Zeus). Beyond that, Sierra Nevada Bill stated that Hop Hunter will be traditionally hopped. The label indicates a moderate and sessionable 6.2% ABV with 60 IBU’s. Most of the hopping was done late in the boil, which will impart the beer with big hoppiness/moderate bitterness.
Whether or not we have a wet hop revolution will have to wait until Hop Hunter IPA officially releases on February 2nd, 2015, but the fact that a wet hop beer is releasing in February is a pretty big step. Look for it on shelves in your area soon after and smell the science.
