Hi all,
I did my first attempt to grow the dregs from several brett beers that I liked. Here is my process. What did I do wrong?
1) Made a 1.5lt starter, 1.040 OG with DME, 1tspn of yeast nutrient and fermcap. Boiled, cooled ~65F and added the dregs from three or four bottles.
2) I left the starter for about two weeks on a stir plate just covered with sanitized foil. Room temp ~70F
3) stopped the stir plate for a couple of days, all the Brett settled in the bottom.
* Until this point everything seemed to be going great. I got slow but active fermentation for several days, the smell was nice.
4) I wanted to step up the starter a second time. So I did the same process, decanted the first satarter and dumped it into fresh wort.
* I tasted the sample and I thought it was fine, of course very thin and not much flavor with no hops but a clear brett character.
5) I left it for another two weeks in the stir plate to promote growth again only covered with foil.
6) stopped the stir plate to be able to decant the wort.
*After a few days a very pretty white pelicle was covering the wort. The smell was of acetone pure strong acetone. I tried a sample and it was horrible, I've never tasted nail polish remover but I'm sure that's how it tastes. So I dumped it!!!
NOTE: I'm very cautios with sanitization. Everything that touched the wort after boiling was very well sanitized with starsan.
So what happened? Too much oxygen? Should I have used an airlock? Any ideas?
Thx
