Back again, this time with a couple of questions about stir plates and yeast starters.
Concerning yeast starters, I noticed that BS2 indicated that using a stir plate increased the yeast population by nearly 2.5 times as opposed to using the same amount of starter without a stir plate. This changed the starter volume from 1.56 liters without a stir plate to .41 liters with a stir plate. I went ahead and made a 1 liter starter just because this is what I’ve always done - should I be able to sleep at night after making a half liter starter on a stir plate for a 1.047 beer?
For my starters, I’ve been using a ratio of 1 gram of DME to 10ml of water, adding nutrient and boiling for 15 minutes. At the end of the boil, I notice that I’ve usually lost around 20% of my volume – I was wondering if this much boil off adversely affects the starter.
Again, thanks to all…
