After a week of primary fermentation, I tried adding about 8 pounds of watermelon puree to my secondary fermenter and took a gravity and taste test 10 days later. The beer still tastes very tart/bitter and not like fresh watermelon. Any advice? Should I be using a combination of fresh watermelon and watermelon extract? Will the flavor improve after carbonation? Should I have used more or less watermelon puree? Should I have used watermelon juice instead of puree?
Also, since I hope to brew a few more fruit beers, I noticed the colour of wheat extract beer is very dark. Should I be using a combination of liquid wheat extract and golden extract to get a more yellow colour?
