Following instructions similar to these, I made my first starter (for my first beer) about 20 hours ago. I boiled water with about 4 tablespoons of Liquid Malt Extract, for about 15 minutes, then cooled it, and put it in a sanitized magnum wine bottle.
I checked the OG on this wort, and it was 1.030 - I had read that 1.040 was better for starter
Once cool, I added Wyeast London, shook hard, and added a sanitized airlock.
I was able to see bubbles coming up through the airlock within the first few hours, but the pace hasn't picked up. I certainly don't see a frothy head, and I was planning on using it in my first batch today.
Does the fact that I can't see a frothy head suggest that I shouldn't pitch it into wort today?
Thanks for any help.
