I just finished my first batch, a Brooklyn Brew 1gal kit, and was unable to split the batch evenly over 8 bottles so I ended up with 7.5. When I went to taste the beers after two weeks in the bottles I received 2 very different flavors between a full bottle and the half bottle. What is the cause? and how can I prevent this issue in the future?
Additional information: I was using 22oz Grolsch bottles and was able to put in about 12oz into that bottle. Since I didn't have a capper I stayed in the same bottle. I did not individually sugar the bottles but placed the maple syrup(in lieu of sugar) directly into my pot. The flavor was more tart and flat compared to the others.
