I recently purchased a vial of White Labs WLP001 for a Robust Porter. When I opened the vial to pitch in the starter I noticed a distinctly sour/vinegary smell. I closed the vial and did a little internet research where I found this on White Labs website
After reading that I decided to go ahead and pitch the yeast. Fast forward to 1 week into fermentation, the beer is displaying the same sour/vinegary smell that was present in the vial. Has anyone run into this issue before, will the off aroma fade or increase in intensity?
Is my beer ruined?
Answer:
People are often surprised by the way the yeast smells or tastes out of the vial; it is hard to judge since it is a concentrated yeast slurry. It is not going to taste like beer. The pH is also lower, so the higher acidic flavor can taste sour. You really cannot tell purity by smell or taste, although it is not a bad practice to try and become familiar with what is normal.
