i have just got back into home brewing after many years (i previously made the wilko canned kits ) and decided to try more advanced kit than i used to do and bought a northern brewer bloc party amber ale kit , ive followed all the instructions and it was bubbling in the airlock quite nicely for about 4 days and has now slowed considerably guide says there s there is at least 10 days primary fermentation left but it is barely bubbling in the airlock only a bubble every so often not as speedily as was but my question is should it of slowed so much after 4 days or has there something gone wrong , i have kept it at ambient temperature as much as possible but could the cold we have been having had a negative effect and is there anyway of saving it if it has gone wrong thanks chris
