Summit Unchained #21: Us & Them

Parti Gyle

For beer history geeks these words conjure up images of the great, old breweries of Britain – Barclay Perkins, Bass, Whitbread, Ind Coope, and Allsopp. They give homebrewers tech goosebumps. But for the uninitiated it sounds like an act of festive duplicity.

Parti gyle is a system of getting two beers from one mash. If you aren’t up on the brewing process, the mash consists of steeping grains at a certain temperature – usually somewhere around 150 degrees Fahrenheit – for a period of time. This steeping activates enzymes in the grain that convert the kernels’ starch into simple sugars that yeast can ferment. The resulting sugary liquid is called “wort.”

Once the steeping is done, the wort is run off into the kettle to be boiled. A lot of usable sugar gets left behind in the grains. Typically they are rinsed with hot water, making a thinner wort which is also run to the kettle. But if that thinner wort is diverted to a different kettle, you have the basis for a second beer from the same mash. That’s parti gyle.

In the olden days, English brewers would use this system to make beers of differing strengths. For instance, they might make an X, XX, and XXX version of their pale ale. As many as three gyles would be run off from a particular mash and then the worts containing different amounts of sugar were blended together at different proportions to make the different beers.

Very few breweries still do this. There are a couple of breweries in England, I am told. Fuller’s is one. Anchor Brewing in San Francisco has done it, making their refreshing Small Beer from the second runnings of Old Foghorn Barleywine. Surly’s Damien is made from the second thread of Darkness.

Summit brewer Gabe Smoley has revived the practice for the latest Unchained Series beer Us & Them. This the 21st beer in the series is actually two beers. 1st Thread is an American-style IPA that comes in at 7.2-percent alcohol. 2nd Thread is a session IPA at 4-percent, made from a second gyle of the same mash. The kettle hopping regime is the same. The dry hops are different.

The results are remarkable. Like siblings that grew up in the same family, these are two very distinct beers, but with an underlying quality that ties them together.

Here’s my notes:

1st ThreadUnchained #21: Us & Them 1st Thread
Summit Brewing Company, St. Paul, Minnesota
Style: American IPA
Serving Style: 12 oz. bottle
7.2% ABV
90 IBU

Aroma: Hops lead – juicy melon and tropical fruit. Pineapple, mango. Faint herbal/floral notes. Low, grainy malt with moderate impression of sweetness. Low esters. Low alcohol.

Appearance: Full, creamy, off-white to ivory foam with excellent retention. Dark gold/orange and brilliant.

Flavor: Juicy hops with sturdy supporting malt. Bitterness is high and lingering, but amply supported by medium sweetness. Bitterness comes on stronger mid-palate. Hop flavor is high and juicy – tropical fruit, mango, pineapple, grapefruit, and tangerine. Sprite-like citrus. Malt flavor is low, neutral-grainy, with a faint biscuit character. Finish is off-dry with lingering bitterness and juicy tropical fruit.

Mouthfeel: Medium-full body. Medium carbonation.

Overall Impression: A super-juicy and slightly sweet IPA with restrained bitterness and bursting hop flavor. Perhaps a bit sweet in the finish.

2nd ThreadUnchained #21: Us & Them 2nd Thread
Summit Brewing Company, St. Paul, Minnesota
Style: American Session IPA
Serving Style: 12 oz. bottle
4% ABV
55 IBU

Aroma: Hops dominate. Bright citrus – lime and tangerine. Apricots. Low, neutral-grain malt with light notes of toasted biscuit. Very low impression of sweetness. Low esters.

Appearance: Full, creamy, just off-white head with excellent retention. Medium gold and brilliant.

Flavor: Hops through and through with a low, grainy cushion. Bitterness is high, but smooth. Bright, lemon/lime-citrus hop flavors, almost acidic. Low floral and apricot back notes. Sweetness is very low. Malt has a dry, toasted biscuit character. The finish is very dry with lingering toasted grain, bitterness, and lime citrus.

Mouthfeel: Light body. Medium-high carbonation.

Overall Impression: Light and bright. Most session IPAs have bitterness levels that are too high for their weight. This one has nice balance. 55 IBU in a 4% beer is still bracing, but it isn’t tongue scraping in this beer. The dry, biscuit malt background is reminiscent of an English bitter.

Summit Unchained #12: 100% Organic Ale

Gabe Smoley is one of the newest brewers at Summit Brewing Company. Unchained #12: 100% Organic Ale is his first entry into the Unchained Series. He went all out to make a certified, 100% organic brew. Says he, “Most USDA certified organic beers on the market are about 95-99.9% organic because it is extremely difficult to find ingredients like organic yeast. This beer is made with 100% organic ingredients including malts, hops and yeast. Summit microbiologist James Fetherston and I worked together to create our own certified organic yeast strain to do this, as there are virtually no organic strains available from laboratories.”

The aim was to craft a light, yet bracing beer appropriate for spring; a move away from the heavy beers of winter, with a hoppy kick to mimic the lingering cold. Drinkers who are too tied to the style guidelines may take issue with calling this an IPA, but they do say “sessionable IPA.” Just drink it and enjoy it for what it is, whatever that may be.

100% Organic Ale launches this week with meet-the-brewer events at bars around the Metro.

March 12: Release Party/Meet the Brewer – House of Pizza, Sartel, 5-7 pm
March 13: Meet the brewer – Brasa St. Paul, 6-8 pm – Brasa St. Paul and Minneapolis will also feature Unchained 12 food pairings from 5-9 pm
March 14: “Hoppy Meals” pairings – Republic Uptown, 4-6 pm; Republic Seven Corners, 7-9 pm
March 15: Firkin Friday with Organic Ale cask – Grumpy’s NE, 4 pm
March 21: Meet Gabe and sample Organic Ale – Four Firkins, 6-8 pm
March 28: Flight Night at Ginger Hop featuring Organic Ale. Flights include four Summit beers total.

Here’s my notes:

Organic-Ale-BTL-web2Unchained #12: 100% Organic Ale
Summit Brewing Company, St. Paul, Minnesota
Style: “Session” IPA
Serving Style: 12 oz. bottle

Aroma: Big aromatics from a fairly small beer. Hops hit the nose first – floral and citrus. Biscuity malt comes in shortly to offer support. Nicely balanced between the two. An undercurrent of candied fruit throughout.

Appearance: Dark golden color and clear. The off-white head is full, creamy, and very persistent. Settled after a long while to a sustained film on the surface.

Flavor: Light and refreshing. Very dry with pithy bitterness that lingers well into the finish. Floral and lemon-lime citrus hop flavors carry through from beginning to end. Some peppery spice in there as well. The malt fills in lightly underneath with a biscuit character that brings a vaguely English flair. It offers enough sweetness to temper the hops, but not quite enough to balance.

Mouthfeel: Medium-light body. Medium-high carbonation.

Overall Impression: This one leans a bit more to hops than I would like, but then that’s kind of the point of the beer. It’s close, but a hint more malt to back up the bitterness would have been welcome on my palate. Brewer Smoley says to drink this around 40°F. I would suggest a higher temperature to bring out more of the malt. While style-sticklers will have issues with calling this an “IPA,” it fits the brewer’s description of “sessionable IPA” quite nicely; light like a pale ale, but with a bigger hop load.

2012 GABF Interview with Summit Brewing Company

A lot has happened at the Summit brewery since I interviewed their brewers at the 2011 GABF. A pilot brewing system was installed, allowing their brewers to test recipes and get a little experimental. The taproom has opened for business and is going gangbusters. Ground was broken on a massive cellar expansion that will allow them to nearly double production. In this interview with brewers Eric Blomquist and Gabe Smoley at the 2012 GABF we talk all about these changes and what it might mean for the future of Summit.

As I was editing the interview I realized that I kept referring to the pilot system as the “toy brewery.” It made me laugh, but it also made me wish that I had explained myself. It almost sounds as if I am mocking the new mini-brewhouse. I meant “toy” as in a really cool thing that allows the brewers to play, much as a 1965 Mustang might be a “toy” to a car enthusiast. The Summit pilot system is REALLY cool. I want one in my basement.
