I am new to this, so please bear with me. I have just bought myself a starter kit (equipment & a kit). I have a question:
The fermentation bin I have has a snap on lid. When I first put the wort + water + yeast in I presume that there will be quite a bit if pressure built up if the lid is snapped on, do I need to fit an air lock into the lid. also, if there is no air lock in the lid how do I know when fermentation is finished?
TIA for your help.
