So my Youngs IPA is hopefully fermenting. It's been 48hrs. I have a couple of questions maybe someone can help with:
1. Fermentation for this kit is supposed to be somewhere between 20-24 deg. In the beginning the temp on the FV was roughly at room temperature. Something like 23 deg. But last night it was creeping up despite the room temperature being the same. I've read somewhere that fermentation raises the wort temp by a couple of deg. Is this what's happening here? How important is temp stability? Is it ok if it fluctuates between 20-24?
2. I initially half filled the double airlock so both 'bulbs' were half filled. Now the left bulb is full and the right is empty. Is it normal? It strikes me as logical as the C02 is escaping pushing air up through the lock.
When should the airlock be changed?
3. At what point do you know if your brew isn't working or is spoiled by possibly amateur (
) cleaning and sanitation?
Thanks for any help!
