Fresh-Hop Spelt Saison with Paul Key
It's wonderful to be out in the Northwest, so close to the hop fields, where every year we get to brew up a special batch (or three) of fresh-hop beer. Paul Key, my fellow homebrewer-geek, had a nice harvest of Fuggle and Columbus hops growing in his front yard right here in Portland. He was able to knock out a couple of fresh-hop IPA's, and I pitched the idea of getting together for some kind of fresh-hop saison. We kicked around some ideas and came up with this: A pale, moderately strong saison, with about 30% raw spelt in the mash (inspired by Brasserie Blaugies' Saison D'epeautre), moderate-high IBU's for the style at an estimated 30+ IBU, and brewed with a blend of commercial saison yeasts. I certainly have high hopes for it, as the spelt mash had a unique character, and the fresh hops, all added at knock-out, had an intense citrus-orange-spice pungency.
We picked most of the hops while working on a long step-infusion mash, with a protein rest. We didn't have much info on spelt as a grain, which we just bought from Whole Foods, but we assumed that because it was a type of wheat, that it would probably have a similar gelatinization point. Wheat gelatinizes at regular mash sacharification temperatures, so if spelt is the same, that means you don't need a "cereal mash" which would incorporate boiling the spelt to gelatinize it prior to adding it to the mash. I have seen a good deal of internet homebrew recipes with raw spelt that call for a cereal mash, and I don't see how it's necessary. Anything I found online suggested that it gelatinizes at similar temperatures to wheat. Anyway, we actually did an iodine starch-conversion test after our sach rest to make sure we had fully converted the mash, and it showed that we got good conversion.
Runoff was aided by some rice hulls, but we had no problems with a stuck mash whatsoever. Probably could have gotten away without them but it's always good insurance.
We bittered with pelletized hops to keep the IBU's somewhat predictable, and used a boatload of fresh hops at knockout only. These sat in the mash for 20 minutes during "whirlpool", and then an additional 25 minutes while we transfered through the heat exchanger. I think this provides a really nice hop profile and it's very close to what happens in a professional brewery.
We lost quite a bit of wort from the hops, which we forgot to consider when designing the recipe, but I don't think we could have done much about it anyway. Based on our kettle size, we made the biggest batch we could. Sometimes it is just better to collect less wort than do tricky stuff to increase the volume, and neither Paul or I are ever hurting for beer to drink. It's OK to have a smaller yield sometimes.
We decided to go with a saison yeast blend for this beer, which is the first time I have tried blending saison yeasts right off the bat. But both Paul and I have come up really frustrated with the Dupont yeast as a sole fermenter in the past, so this blend will be worth trying in a few beers. We decided to pitch both the "Dupont" strain and the "French Saison" strain, with twice as much Dupont yeast. The fermentation was started rather cool and ramped to 80 over a few days, a good compromise between the French strain which produces plenty of character at cooler temps, and the Dupont yeast which can't seem to finish out if it drops below 85 degrees. The French saison yeast will definitely help attenuate the beer faster when the Dupont yeast slows to a crawl in the last 1/3rd of fermentation.
On a side note, the French Saison yeast has been a bit bothersome for me in the past too, it definitely has its own problems. I have noticed that it tends to dry a beer out almost excessively, so that if there are any tannins from grain extraction at all, it tends to accentuate them and leave an annoying tannic astringency in the beer. We tried to alleviate that with a good dose of calcium to the mash and the sparge water, which should keep the pH low and avoid extracting any harsh tannins in the first place. I think that should help.
Well, I'm looking forward to tasting this beer and using the blend in at least one other brew. If you brewed any interesting fresh hop beers, feel free to brag about them in the comments. Cheers!
