Bought a brown ale beer kit online back in late March, but due to a ton of "reasons"(including putting in a new kitchen) I wasn't able to brew until now (6/1). I refrigerated the yeast and hops as soon as I received the kit.
Yesterday I made my first yeast starter, using the White Labs British Ale yeast WLP005 from the kit. The "best before" date on the yeast is June 8, 2012 (one week from now). I took it out of the fridge about 4-5 hours prior to pitching to bring it down to room (fermentation) temp.
I used a yeast starter kit from Northern Brewer. Followed the directions, using 650ml of water and 1/2 cup DME. Boiled about 17 min, cooled wort down to about 76-77 degrees (slightly higher than the temp I will ferment at, hoping this 6-8 degree difference won't have any affect), then pitched the yeast, which seemed slightly "clumpy". And I unfortunately forgot to add yeast nutrient.
Stirred the starter frequently last night, as well as this AM. When I first checked this AM, there was no krausen at all, and about a 1/4-3/8 inch layer of yeast on the bottom. I would assume that that is a significant amount of growth... correct?
Is the fact that there is no krausen reason to be concerned?
Thanks for any feedback!
