Recently started making 1250ml starters for all my brews. Prior to this, I always pitched a swollen smack pack directly and start times were around 12-18 hours with visible fermentation lasting 7-10 days. Now, with my stir plate starters, my average start times are around 4 hours and visible fermentation ends within 72 hours. Gravity checks show FG's within 5 days. I have only used WLP001, 005, 320 since using starters and am planning to try the smack pack again with a starter for comparison. Just wanted to say that starters are great and wish I would have used them in the past.
