First Berliner Weisse - Standard no boil, 50/50 Wheat and Pilsner Malt. OG 1.045.
I pitched a 1L starter of WLP677 (about a 1 week process) that tasted very sour and kept the fermenter around 80F with a heating pad. Two weeks later it was not very sour and the ph had only dropped slightly. I then pitched a 1L starter of WLP 672 (also 1 week) that also tasted very sour and kept the fermenter around 80 with the same heating pad. Saw pretty active airlock activity for a few days after. Two and half weeks later it was still not very sour and had a ph of around 3.8. I moved it to the attic where the temperature remains 95+ degrees, maybe even hotter. A little less than 2 weeks in the attic and it is around 3.5 ph.
My questions:
- This process seems awfully slow for a pre-fermentation souring. What's wrong?
- Is it ok to taste this wort after sitting for so long at room+ temperatures? Its not showing any signs of infection but it makes me nervous to have a wort sit this long without a yeast fermentation. No sanitizing process is THAT thorough to get everything.
What should I do now (or next time)?
