I’m not certain, but I’ll bet it turns out good. I will eventually give it a try warm. The last time I used it, ferm was down about 53 F or so and I was very pleased. Very clean, zero sulfur or diacetyl.
It should be ok. The range is a daytime high in the high 50s, lows at or near freezing. The garage is attached, but should stay 50F or below.
One time I brewed late in the year, the weather suddenly changed to highs in the 80s despite the predictions. I was not happy with that batch. My conical is what I will use for temperature control is a cold garage, temp controller with themowrap around the conical.
I recently brewed a Maibock with S-189 at 54F and I’ll keg it this week. When tasting a sample for FG it was great without any off flavors. I think it will be a great beer!
How did the march lager work out? The weather nowadays is so fickle and way warmer than I was a kid, it’s hard to say what temps I’ll have, but I intend to brew a bunch with S-189 over the next while.
