Stout problem

[Bob from Snobs]

Is it sour or does it have a tart character to it. I ran into this problem as well and it was the water, basic dry English stout. I normally mix my well water with RO % depends on style but on dark beers I just use straight well. On the one that came out with tart notes in the finish I used 50/50 RO to well water. After several discussions with the brew club, I brewed it again with straight well water and tartness was gone.

I also should mention my well water if a community well.

 

[Bigbre04]

70kgs pale ale
10 kgs choco malt
7kg carafa 80 deg c°


Hops wilamet 4.3 alpha acid
Yeast no. 5

This is a low ABV stout that i am about to package today. finished at 2.8p from 11.8 which puts it close to 4.8% abv. I could have subbed out the chocolate for additional RB. It is nice and light while still having some body and a nice balanced flavor.
