I brewed my third batch on Friday. It is a milk stout with OG 1.066. I was planning to use dry American ale yeast but the LHBS was out so I purchased a wyeast smack pack. I knew these were designed to be pitched in 5 gallons so I did not make a starter. After I pitched I noticed that the package said it could be pitched in wort up to 1.060. I know the lactose I used probably accounted for 6 points so I may be ok. Should I go buy another package of yeast on Monday and pitch it or should I just RDWHAHB? Fermentation appears to be pretty active already.
