mainly because i had a guess. my other beers have been using the coopers enhancers and the brewcraft stuff.
iw would this be better
1x Coopers lager (came with the kit)
1x Home brand lager
500g of LDME
250g of of Dextrose
250g maltodextrine
12g of Hallertau hops steeped for 15 mins
and 2x 11.5g SAFLAGER S-23
and maybe dry hopping once primary has finished.
like i said im a beginner and learning.
I still reckon you don't need either of the 250gm dextrose/maltodextrine additions.
Say a normal brew is 1 can of coopers goo and 1kg of fermentables (sugar, malt, Brew Enhancer 1 or 2 etc etc)
That will give you on average 5% or so of Alcohol.
If you add another can of goo for a toucan that pretty much replaces the need for the kg of fermentable material/sugars.
So normally you'd just open two tins of goo and whack 'em in the fermenter for a toucan brew.
You can improve that by maybe a hint of LDME to smooth of the isohop biterness that you get from two tins of goo (both your cans of extract are hopped, so that is a higher IBU than a tin of goo and fermentables).
But I wouldn't add that much extra dex. Even with two yeasts I'm thinking the flavour won't be greatly improved by the dex addtions.
Maybe dry hop is the way to go as it won't add too much bitterness, more aroma which is what you want.
I have a toucan stout aging at the moment and it's a cracker but it was:
1x Cooper Stout
1 x Coopers Dark
250 gms LDME
15gms fuggles at flame out.
It's a cracker, very heavy lots of mouth feel and not too bitter because of the LDME.
Previously as a benchmark I did a straight up Coopers Real Ale with a tin of homebrand draft and nothing else and it was hellishly bitter.
Took several months before it was drinkable and it's still getting better each month that it sits in the bottle. It's very dark/rust coloured and has a thick foamy head.
Cost was under $18 for 22L as the homebrand draft was on special.
Not my best ever brew but I do love the "supermarket challenge"!
