I’m starting off another Wilko Merlot 6 bottle kit this weekend. When I did the first one, I followed the instructions, which advised I only half fill the demijohn for the first week because the fermentation is more than a tad vigorous and then top it up once it’s calmed down a bit. The only problem with that is that I can’t take a hydrometer reading with just half the liquid, so I‘m going to do the next kit in a 10litre fermentation bucket and just put in the full 5 litres of water at the beginning. The only issue with this bucket is that it doesn’t have an airlock, it’s just got a lid? My question is does that matter or could I just cover it with a tea towel and let the whole thing just ferment?
Any advice would be welcomed.
