I just had another peach and blackberry sour. Man, are they great!
There's some "funk" in there from the Lacto and they are insanely drinkable. Yesterday I liked the peach more (both being terrific), but today I actually loved downing the blackberry more. It's so hard to pick a favorite. You know you've got good beers at that point
I wonder if a fruited section on the Wiki would be a good addition. Honestly, it's no different than making fruited beer. Frozen fruit does wonders. Follow pasteurization steps, including "mashing" (not in the beer sense) while it is heating to "smush" it all up. Add some water if needed (only what is needed), and let it sit at 155-160F for the correct time. Pour into primary 3-4 days after fermentation. Using a large muslin sock will easily keep all seeds and skin from fruit intact. Weighing it down with .5LB or so of dollar store marbles is not a bad idea. Things to note is that you should not expect fruit flavors to be as much "forward" with lacto present, it's just not going to happen. But after a few sips, you can easily taste the hints of whatever fruit you put in. Making fruited sours is easy, makes your beers look beautiful, and really adds a hint of flavor to an already flavorful beer. I'm absolutely sold on the 67% 2-row + 33% white wheat formula for all fruit beer bases.
I was SO worried about head retention. You could have a topic on that. I can tell you with what I just brewed, the head retention is absolutely comparable to non-sour beers. I can pour a glass, and there will still be a 1mm or so head at the edge of the glass after 20 minutes if were to leave it, with a slightly film mostly in the center. This is likely due to the pre-acidification, which I would make sure to make a point of in the wiki too. Not only that, but the lacing will follow the beer as it drank. Not only did the taste blow my expectations, but the actual look, as it was being drank, presented itself flawlessly.
The picture I attached is the girlfriend's peach sour after 20 minutes of sitting, I kid you not. The reason it wasn't completely drank is because she was rushing to get some gardening done. I think the pic speaks for itself.
