Well I finally brewed last night. It was about 9PM when I pitched my yeast. When I woke up this morning, the airlock was bubbling away. I get a bubble at least every second, even now at nearly 3PM.
This was my first starter and I must say, this is the fastest and most vigorous airlock activity I have had to date. I am now hooked on starters. I am going to tweak my stir plate a bit and start another starter to brew this weekend. Thanks all !!!!!!
