This is my second home brew. I chose "Coopers Mexican Cerveza" with "Muntons Beer Enhancer".

It's only day 4 out of 7 weeks but on the second day, the whole bin warmed slightly and there was a lot of bubbling. The bubbling stopped on day 3 and now there's little action - just a few bubbles in the middle. It's about 16 degrees centigrade house when the kit said about 17 so this should be ok? Should I keep the bin shut or can I peak? I have been peaking every now and again - is this a silly idea?

Thank you :).
