I have some questions that I hope you guys might be able to answer for me...
1) I have a couple of 25L brewing drums and one 30L. If I make up a beer kit to 23 Litres total I notice the bubbling in the air-lock for the 25L drum is usually one bubble at a time but in the 30L drum it seems to build up some pressure and releases a series of bubbles in the one go. Is the extra head room in the 30L causing this?
I also notice that the air-lock can form a water bubble up near the top of the air-lock. This does not seem to cause any problems but it needs enough CO2 pressure to build up before it releases.
2) How much sugar maximum can I add to a Coopers 1.7 Kg kit in a 23 litre brew using the supplied yeast sachet before before the yeast has problems with the alcohol levels?
3) This might be related to the above. I read that adding DAP is a good idea when there is a lot of sugar used to aid in fermentation. Should I be doing that it a Coopers Draught kit brew when 1.5 Kg of white sugar has been used.
4) Is it ok to make a brew of whatever when the total volume is only 4 Litres in a 23 Litres drum. I'm guessing that it would take some extra time for bubbling to commence in the air lock.
