our brewing session has been moved up to tonight. i had planned on making a starter, however the instruction say the starter should ferment for 12 hours prior to pitching. i just smacked the pack a few minutes ago and need to let that swell for a bit. the question is that if i do make a starter and give it 5-6 hours to ferment, will i get worth while improvements to my yeast? or should i just pitch my smack pack?
