Don't want to tread on anyone's toes but extract brews that I have done don't taste any better than a decent 2 can kit.
So I'd advise just switching to all grain. By all means try some oven top small batches, but I went straight from many, many years of kit brewing to full 23L AG brews and my only regret is that I didn't think to go bigger, as it takes more or less the same time commitment no matter the size of the brew. (5 hours approximately but there are some forumites here who split that over 2 days)
All you need for a 23L BIAB AG brew on top of the equipment you already have for kit brewing is a boiler and a BIAB bag - round about ã100. AG brewing is cheaper than kit brewing anyway, so it doesn't take long to recoup the investment. (less than a year in my case but maybe you're less of a p***-head than me).:lol:
+1.
There is no point at all in my humble opinion, in going from kit brewing to buying dme and doing extract brews. I would go right into All Grain right away. If you are unsure do a couple of stove top brews. If not, buy a boiler and get going big style. I don't regret doing a few 10 litre stove top brews, I got confidence without risking anything much and realised that I could make vastly better beer than the kit brews I had made.
DO USE A GOOD RECIPE....I wasted some time and materials inventing my own recipes with very little knowledge. That was daft. There are great recipes that are simple and will guarantee a lovely ale.
This one is a favourite of mine:
23 litres finished volume.
6kg Pale Malt
150 grms Crystal Malt
Mash in 15 litres of water for one hour at 68c
Drain into FV to store temporarily
Sparge with additional 15 litres of water at 75C
Boil wort for one hour
Hops:
22gm Magnum for 60 minutes
37 gm EKG for 10 minutes
37gm EKG at flame out.
Cool as rapidly as possible to 20C
Pitch Nottingham yeast (Gervin Ale Yeast - wilkos for about ã1.20
This should come in as a lovely IPA between 5.8% and 7.8% depending on your efficiency.
If your pot won't accommodate the volumes just scale it back. These amounts assume a 23 litre finished brew.
By the way - if you buy bulk materials like 25kg grain from suppliers like Geterbrewed, that whole recipe would cost about ã11 - - Six pounds fifty for the grain, one pound twenty for the yeast and about three quid for the hops. You just can't loose to get five gallons of high strength wonderful beer for that.
