My first batch I made in February was the Brewer's Best IPA. I left it in the primary for 7 days. It was fermenting at a temperature of 60-65 degrees. When I took the specific gravity at the time of bottling it was the same as when I transferred to the secondary fermenter. Does this mean that I could of bottled on day 7 versus transferring to the secondary fermenter for another 2 weeks? There was no krausen foam on day 7. Does this mean I didn't need to leave in the primary for 7 days? The SG on day 7 was already in the range of the final gravity.
Now on to my second batch.......... I just brewed the Brewer's Best Rye Pale Ale. With it being the summer now, the brew temperature was 73 degrees this time in my basement. The fermentation began much quicker this time, probably due to the temperature increase (? also possibly due to stirring in the dry yeast versus just sprinkling it on top). After 3.5 days there was already no Krausen foam on top. I took the SG and it was already in the range of the final gravity on the Brewer's Best instructions. I made the decision to transfer it to the glass carboy. The recipe called for dry hops. I added the dry hops to the carboy with the intention of leaving the beer in the carboy for 2 weeks. However, the next time I looked at the beer there was a new .75 - 1 inch Krausen foam (I think that's what it was). It lasted about 3 days before settling. Is this a normal reaction after adding the dry hops or mean that it could of stayed in the primary fermenter longer? Do most people add the dry hops right away to the secondary fermenter or wait a week or so (if leaving in the secondary for ~2 weeks).
Thanks for your help and suggestions to a newbie brewer
