So I added coffee to my oatmeal stout and it's had this kind of sour off-flavor, I imagine from the acidity of the coffee. It's been like that since the week I kegged, which is when I first added the coffee.
Came back from vacation and pulled a beer, great flavor, could taste the melding of malts and coffee, no sourness. Same thing today, first beer was very good.
Only the *second* beer and every beer after has that sourness or weird flavor. Some flatness and lack of head, again from the second beer on. I would think that if it's in the lines the second beer would be better.
I had chalked it up to the coffee needing more aging, since the first one tasted good after not pulling a beer for a few weeks. But now I'm back to that sourness.
Might be some kind of separating between the cold brew and the beer that then gets mixed back together once it's poured a few times. Here are my thoughts:
1. Pour a beer from the tap
2. Pour a second beer
3. Taste directly from the keg (open it up and take some beer)
Solutions:
4. Replace tubes and disassemble faucet to clean
5. Clean and disassemble keg for sanitizing (ideally I'll find the problem and not have to dump anything)
Anyone ever have a similar issue?
