Am I missing something I do BIAB and yes it does take time but when its mashing for whatever time I sit and watch tele boil for whatever time sit and watch tele sterilise towards end of boil cool with wort chiller then put in FV job done. Obviously I check it from time to time but that's all . Maybe I am doing something wrong but it works out well. As for the original question depends what you want I like grain cos even if I did the same recipe there are so many variables it could turn out different each time which is fine with kits there are less variables so same all the time.
Nope, I do the same. It's purely that you have to be available during that time, maybe stir once or twice. Extract or AG, you still have to clean up at the end, and that's where the real work is. lol
It's just the length of the "brew day" that's different really, as in the time slot within which you are doing your brewing. Like yesterday, I prepared my water at 7:30am (so that marked the start of my brew day), and had finished cleaning my equipment and putting it away by 5:30pm (marking the end of my brew day). The fact that during that brew day I'd watched a few episodes of a show on Netflix with my wife, and eaten lunch, well that's easy to ignore and besides the point if you really don't have a single day in which you have 6 or 7 hours where you can be available to brewing (my day was longer as I faffed more, eg. instead of lifting the BIAB bag, I drained the boiler into a clean FV, THEN raised the bag and let it drain etc, so my wife didn't have to help.)..... lol If you only have 2 or 3 hours, throwing some malt extract into water, bringing it to the boil and adding hops, well that can seem much more attractive. You've still have to prep your water at the stat though, and clean your equipment at the end.
For sure though, a HUGE proportion of an all grain brew day is spent just waiting. Waiting for water to heat up, waiting for your grain to mash, waiting for the wort to come to the boil (ok, if you don't have a built in stirry thing in your boiler, you're stirring your wort the entire time during this particular wait.... lol), waiting whilst your wort boils and until you hear the alarm for the next hop/boil addition (I use Beersmith 3 phone app)… With short spells of intense activity every now and then. Leaves me tired and achy still though.... lol
