Ok, can someone help me with this... I've been making yeast starters for my last 8 batches of beer. I've been following the procedure correctly, from what I can tell:
- 1 g DME per 10 mL water, boiled, cooled, pitched into sanitized glass container with smacked and inflated yeast pack, swirl every time I go past.
After 24 hours or so, there seems to be activity as you can hear gas releasing when you swirl it, and it gets a good head of foam when swirled.
HOWEVER, every time I take a gravity reading after it should be done, I get anywhere from 1.030-1.040... instead of the 1.010 it SHOULD be.
Suggestions? I've asked a lot of experienced brewers about this... no one knows what it could be. Anyone else ever have this problem? Do I just need to buy/build a stir plate?
