Alright, so I'm a little paranoid with an infection in the last few batches... Anyhow, I'm working on a Two Hearted clone and got a bunch of yeast from bottles that has been going (bumped it up to about a liter last night). When I stepped it up last (and I'm a fairly careful brewer) I noticed it was fruitier than I expected, both in the aroma and flavor, and (if I'm not imagining things) there was just a hint of vinegar to the flavor. I was careful, hit around 1.040 with the gravity, added just a few hops pellets and some yeast nutrient. I know that starters aren't beer, so I'm wondering what the consensus is... should I pitch it? Should I throw it out and play it safe with Nottingham or Safale 05. What would you do? (And thanks in advance for your help.)
