I don't know why I keep getting comments about opening the vessel multiple times. I have only opened the top cap a couple of times. When I draw off a sample I use the spring loaded spigot at the bottom, and I don't know why some people think there is a problem doing that. Sometimes I think people make negative comments just because they can. I have tasted this batch of pale ale several times and it tastes better each time I taste it. The instructions for brewing this pale ale state that it should be in the fermenter for 3-4 weeks. Today is the 19th day.
