    I’ve brewed with virtually all of the commercially available German lager yeasts but I think I’ve found my new favorite. It’s subtly malty, lets the hops come through elegantly and with an underlying bready note. It took about 2 months to “clear,” (I use the term clear quite loosely), but always maintained classic German unfiltered lager characteristics while still having a clean taste. I brewed a 5 gal batch with 7 lbs Czech Pilsner Malt, 4 lbs BestMalz Red-X, traditional step mash, hopped with 1 oz Tradition at first wort, 0,5 oz Perle at 60 min, 1 oz Spalter at 25 min and 1 oz each of Tettnanger and Spalter in the whirlpool. Delish

    I brewed a LODO country helles with this yeast based on the Brewing German Helles paper. The recipe called for sauergut culture at knockout which was also used. The resulting beer was astonishing to say the least. It was as good as any German lager I’ve ever tasted, and the best beer I’ve ever made. Incredible malt flavor and aroma along with the grapey German “it” factor from the sauergut. The first keg blew in a week because we couldn’t keep away from it. The second keg had a seal leak which wasn’t discovered until after lagering. Evidently air got in because the beer had developed a prominent diacetyl flavor component. So my advice is to take great care not to introduce oxygen into your process post-fermentation because this yeast will produce diacetyl if given a chance. I’m giving this beer five stars based on the first keg. The second keg was my fault. This will be my go-to helles yeast from now on.

    I have used this in a few beers now and it has been great in them all. First I went with a zwickel which was great and the most recent was in a gratzer. The yeast is very versatile, going from the unfiltered zwickel to a crystal clear gratzer that took first place in the historical beer category in a recent homebrew contest hosted by the Maltose Falcons.
