Every time I brew a beer I keg it in a 5 gallon keg. The first gallon or so is okay beer but then about half way through the beer gets spot on. It's a really good brew. What is going on with the first gallon? Why does it taste different and frankly slightly off. Is it that it needs to age in the keg for a bit, or is it that there's some heavy funk that settles to the bottom. Perhaps I need to leave a bit in the carboy before I keg. Do I need to use some sort of fining to push the funk to the bottom before kegging? It's not that the first gallon is terrible beer, I drink it but there is a noticeable difference after about a month in the keg and 1-2 gallons in. What's going on? How can I get the beer to be more consistent throughout the keg? On a side note, It's not that I'm getting drunk and then it tastes better!
