I am in a bit of a quandary with a yeast starter for an English Pale Ale with gravity of 1.055, 5.5 gal, and stir plate. I have one packet of Wyeast 1028 with a date of Dec 11, '12. I anticipated doing a two step starter. When I plug it into Mr. Malty, it maxed out, with stir plate at 2 packets in near 2 liters. So, I need to step up. Then I plugged it into YeastCalc, same parameters, it suggests 1 packet, 2 liters, good to go. I am either missing something or this is a fair discrepancy. I have read W & Z Yeast book and other books concerning starters but I am still a bit in the dark about the second step procedure for a starter. Any help would be appreciated. Thanks.
