Well my first batch of Berliner was a drain pour. I did a 5a sour mashed version with wheat, pilsner, and acidulated malt. I mashed in a 10 gallon cooler, cooled to 110, stirred in a couple handfuls unmilled pilsner grain, mash covered with plastic wrap, flushed with CO2, and held for close to 48 hours. Fermented at 66 with US-05. It started at 1.032 and finished at 1.007.
It had a light odor in the mashtun but nothing serious. The aroma actually got stronger after a 15 minute boil, and worse still after fermentation with US-05. The taste is actually not bad but the aroma is so off putting there is no point in drinking it.
I had three other home brewed Berliners in the last couple weeks to compare to mine. Another Sour Mash with a near identical process to mine that turned out very cloudy, almost milky, slightly sour, and a little to sweet (finished at 1.012). It did not have a bad aroma but it seemed to lack any good aroma as well. It was just sort of blahh.
The other two were both normal mash, short boil, lacto fermented beers. One was lacto culture first and finished with ale yeast. The other was fermented with the mixed White Labs Berliner blend WLP630. Both were clearer, lighter in body, dryer, and crisper that the sour mashed version but they were both less tart/sour. One was a shorter fermentation so they may not have given the lacto enough time. The one with the blend was aged for a few months but it may have benefited from a warmer fermentation where lacto would have performed stronger.
Despite my drain poor first attempt there was enough positive going on in the beer that I am still ready to try again. I ordered some more malt and a vial of the WLP630. I also acquired a lacto culture from one of the brewers of the other beers I sampled.
I will be doing a 10 gallon batch mash at 148 for 1 hour, 15 to 30 minute boil to hit volume and gravity, split into two carboys, One is getting a WLP630 starter and I will let it got for at least a month or so. The other is going to get a straight lacto culture for about a week or two then it will get a Brett Trois WLP644 starter to finish.
