My last few Belgians have been coming out with this sour-like flavor to them. They are not too overwhelming, and some people actually liked them how they were. I'm not a fan though.
I made a pumpkin spiced belgian red I made back around Christmas time that had a sour quality to it, but overall the beer was good. I thought, and still may believe that it had to do with my use of the pumpkin; I boiled it rather than steeping it with the grains. The boiling process may have caused the slight sourness to the beer, but I can't be sure.
The Winter Wit II I made a couple of months ago had a similar sour-like taste to the beer. I wasn't too happy with it, but am drinking it down anyway. Others still seem to like this beer too, just like the one before.
The 1st Tripel I made came out great; there was no sourness to the taste, and I was relieved. So I made another Tripel, but this one is tasting sour!
This one is only in the bottle for 2 weeks, and maybe the flavors still have to change a whole bunch, but my last Tripel tasted fine after 2 weeks; nothing sour.
The other change in this Tripel recipe was in the yeast, an area that can have a great impact on the taste of a beer. In my 1st Tripel i used a vile of WL Trappist Ale Yeast mixed with a 2nd generation WL Belgian Wit starter. In the new recipe I used a vile of WL Golden Ale Yeast, and a vile WL Belgian Wit yeast.
I made a Chocolate Stout that came out delicious; no sourness. This sour thing seems to be only happening to my recent Belgians.
The temps for the Belgian ferments have been between 67-70F
I want rid of this sour taste in my Belgians! If you have any suggestions, please help!
