You may remember the story about how Gruntled Sour Weiße came into being. I had come across a recipe by Billy at The Homebrew Academy for a Gose (see Gose Homebrew Recipe) in which he sours at bottling time with 10 tsp of 88% lactic acid.

I decided to try the same technique for my own Sour Weiße. I soured to taste, but I over-did it a bit. Still, it was nice to blend with other beers to add some tartness.

Superbowl weekend I decided I wanted to do a little batch of beer. Since I had most recently done the Gruntled Sour Weiße at a small size, I decided to simply re-use most of that recipe. This time I thought it would be fun to throw in some mixed berries to add some fruitiness.

At the time that I did the recipe, I knew I would add less lactic acid than I did with the Gruntled Sour. I wasn't 100% sure I'll add any. The bottling-time decision was to add the amount I was planning to for the first beer.

I liked how the resulting beer turned out. I don't really consider it a sour beer. The lactic acid does add some tartness, which compliments the mixed berries quite well. Generally speaking, I don't go out of my way for fruit beers, but this one is a nice refreshing low alcohol beer. It is really quite pleasurable to drink.

Even the Beer Model doesn't think its too sour.

The experiment was a success.

Geeze. Can't believe I still have not commented on this. Brew day went ok. See Gruntled Berry Weiße on the blog. Have not really been paying attention to the fermentation. Started at 60ish it is now around 68 and there doesn't seem to be any activity. I am assuming it did its thing while I wasn't paying attention.

Took a sample. It is very pink. The berry flavor is much more subtle than the color contribution. Think this will actually compliment the lactic sour nicely. 1.008 gravity.

Bottled the pink beer today with 2.5oz table sugar. 13 12oz bottles. 2 bombers. 1 PET liter bottle. 1.007 fg. 3%abv. I really like how the very flavor and the lactic sour play together. Much less tart than Gruntled Sour Weiße. Think this will be a pleasant easy drinking beer in a couple weeks.

PET is rock-hard. One more week of carbonation and we'll see how it turned out.

Put some bottles in the fridges. Should drink some tomorrow.

Had some yesterday. Lots of berry flavor. A little tart, but not what I would call sour. Pretty good. Not great.

Had a bomber over the weekend. I think I liked this beer better than the last time I had it. It really is pretty good. Nice tartness is almost, but not quite sour. Lots of berry flavor. Pretty nice.

Had one with PC last night. Tastes about the same as before. PC was not a fan. Said it tastes more like wine to him.
10/18/2015 esheppy
I think this beer is all gone.
10/18/2015 esheppy
Actually, I have some in the beer fridge.
04/30/2016 esheppy
Past its prime for sure, but stil lactic and fruity. Still pretty good.
05/01/2016 esheppy
Think I finished off the last of these blending with Melting Stream. Really like the blend.
