As this is not a brewing forum , I won't go into the whole process , system selection ect ect ..
All grain brewing can be as simple or as complex as you wish too get.
A very good way to get into AG is with BIAB , Brew In A Bag
and the brewing forums have heaps of threads / sections covering
all you need ..
A "SMASH " Single Malt And Single Hop brew , is a very good way to learn the flavors
aromas and body that different ingredients impart on your brew. While still getting
good beer to drink ..
A typical session beer of around 4.5% can be brewed in around 3.5 hours.
Go to Wo .. then its just the same as a K+K {Kit & Kilo} , but so so much better .
As with brewing any beer , Temperature control of the fermenting Wort is one
of the biggest factors in the production of a quality beer at the end .
So for arguments sake , say I start a brew sat morning , I'm washed up and packed the brewery stuff away by lunch , with the wort in the fermenting box cooling the last few points . Pitch a yeast onto it sometime before bed ... Come Friday arvo turn the fermenting box down too 2°, then sat morning while the brewery is heating up I can keg last weeks brew , wash up the fermenting stuff , knock out another brew , force carb the keg . and sit back Saturday arvo with an all grain beer that is 7 days grain too brain ..
It can be done and there are plenty of examples of it on the relevant sites .
Cheers
