I am making mead for the first time using honey from my hives. It has been going for 3-4 weeks and I'm not sure if it's time to rack it. The fermenting has been slow, which I think might be due to the coldish (60 degree) temperature in my house. I didn't heat the honey and it settled to the bottom of the carboy almost immediately. There is some bubbling doing on, a gurgle about every 10-20 seconds, but it never got more than that. At this point, all the settled honey appears to have been eaten by the yeast and now it's all a uniform color. However, there is no head on top and no sediment on the bottom of the carboy. Should I keep it going in this carboy for a while? This is my first time home brewing of any kind, so I'm a little unsure.
