Hi, this is my second batch of beer that I am brewing from a coopers can and noticed some major differences between the two different times. The first batch I brewed came out with an alcohol percentage of about 4 percent and had an apple taste to it which i believe was from excess aldehydes. This time I believe I used more sugar and had a very vigorous primary fermentation. Once I transfered to the secondary this time I noticed that the amount of bubbles coming out of the airlock was almost nothing. The first batch I would get a bubble about every 5 seconds or so but this time its more around one bubble per minute. It has been in a secondary for about 5 days now and has stayed at that rate since. The kit says to leave it in the secondary for up to 10 days and i was wondering if it was worth it or is this batch probably going to be a dud. Thanks
