wow I am excited and shocked at the quick response from my little yeasties. What I did was at about 11:30pm last night when I started my brewing, I took a 1 gallon regular water bottle. the same one as I use for my blow off bottle, and sanitized it. put in about 1 to 2 cups of water and about a 1/4 cup of light DME added my little yeasties dry Safale US50 to it put the can on gave it a good shaking then just left it on the counter. we I finished brewing and getting wort temp down to about 74* I pitched it. that was at 3:00 am Just before work at approximately a 2:00pm I nice big foam was building and when I got home at 1:00 am this morning form work, the blow off bottle was showing some real big additions to it. So I am really impressed with how quickly the yeasties became active.
