Hey I'm hopefully going to try an AG in a burco I've aquired recently. Do I need to sanitise the boiler before use as well as the grain bag, or does the fact that I'll be boiling the wort in the boiler cover that? How does anyone else cover this? And do you drain the wort through the burco tap, or do you siphon out? I'd imagine using the tap would help with aeration.. Many thanks!
