Hops, hops, hops. Everything’s coming up hops at Worthy Brewing Company.
Because of Roger Worthington’s ties to Indie Hops, a company that makes pellets, and its experimental aroma hop program with Oregon State University, Worthy is the main brewery to test out these new varieties.
As Zach Brenneman, Worthy’s head brewer, explained, “They’re working on developing aroma hops that have good brewing qualities, are disease resistant, have high yields and vigor. We may brew with one that consumers really love that’s disease resistant, but doesn’t have good yield.”
It can take years to find a hop that meets all the criteria. Worthy’s 5-barrel pilot brewing system was created for this trial-and-error process. Until the hops prove themselves consistently over time, they are simply identified by number. Last year, Worthy’s team brewed up four pale ales using the experimental varietals 1007-35, C1002-37, G9-1-374 and C115L-1.
“We use a very basic pale ale malt profile and our standard house yeast for these beers,” Brenneman said. “We make the same base beer for each of these brews to focus on the hops we are using. The finished beer will be 5% ABV and in the 30-40 IBU range.”
They served tastings of the four beers at the Bend brewery and several locations in Portland. Brenneman was at Produce Row Café sampling. “In talking with consumers there, I was interested to see how deep some people wanted to dive into this,” he said.
Some of the comments from the tasting cards:
“Would be good in a helles or kolsch.”
“Nice if you are sick of the IPA trend.”
“Super complex, but too assertive.”
“Almost too mellow for a pale ale (like a lager with hop character).”
“Not bad, just not my thing.”
More in-depth comments are solicited from tasters at Worthy. “Our panelists are given instructions on what we are looking for as we taste through each of the beers so that we can send back the best, most informative information about the breeding program hops we brewed with.”
So far, the brightest star of the program, most grown on OSU’s research fields, is Strata, formerly known as X-331. “It has outrageous oil and it’s more in your face. Tasters note its distinct tropical fruit flavor and its dank fragrance similar to cannabis,” said Brenneman. However, Strata was a surprise hit, especially for brewers. In initial sensory evaluations and onsite rub and sniff comparisons, it didn’t stand out.
Worthy’s blog post about Strata said the following: “Until the harvest this fall, the supply of Strata IPA is limited. The 2016 harvest from 9 acres, grown at Goschie and Coleman Farms, was around 18,000 pounds. It was considered a ‘baby’ harvest, the first after the establishment year. The one this fall will be the first mature crop. Reports from the farm are that it’s vigorously growing and yields should be above the average of 2,000 pounds an acre last season. This spring, Indie Hops planted another 60 acres in the valley.”
Worthy’s StrataSphere IPA won a gold medal in the Sessionable Hoppy category at the 2017 Oregon Beer Awards. While it can take 10 years or more to develop a new successful genotype, this one was on an accelerated path of about six years. Strata is an open-pollinated hop, which means seeds that breed true, developed from a German Perle hop.
Strata IPA has been a consistent favorite at Worthy, with its sales often equal to those of the flagship Worthy IPA and in some weeks exceeding it. It’s available in draft only, but after the harvest plans are to package it in 22-ounce bottles.
This fall, Brenneman looks forward to getting a jump on brewing with the experimental hops and plans to dive right in after the fresh-hop beers are finished. He receives the chosen hops from Jim Solberg at Indie Hops in 2-pound foil sacks that have been bagged under gas. Ten pounds of whole-leaf hops are then used for pilot batches. “Our goal is to do a late kettle add and then dry hop in 1 to 1 1/2 pounds per barrel,” he said.
This year Brenneman wants to brew them in pairs — maybe even two on the same day. He would like to have eight experimental beers available during several months to have more options for consumers to taste and compare.
The goal is to keep brewing well-made, balanced beers and involving consumers who are invested in what might be the next new big hop as well as bring new genes into the hop pool. Close to 90 percent of the hops that Worthy uses are Indie Hops grown in Oregon.
You’ll actually find six rows of experimental hops at Worthy’s ever-expanding brewery and pub as part of its demonstration garden. Shaun Townsend, OSU aroma hop breeder who’s directing the hop development program, chose the varieties that would be planted in Bend. Although most of the test fields are in the Willamette Valley, researchers wanted to see how climate and pests would impact hops in Central Oregon.
