Partial Mash to use up a kit

Post #1 made 13 years ago
I am keen to do my first BIAB attempt using malted barley, prior to atempting gluten free with malted millet and buckwheat. I won't be able to drink this beer, as it contains gluten, but it will be for visiting mates and family.

Due to my target drinkers, I was looking at doing a fake lager with US-05 yeast, fermenting as close to 15C as possible.
I wanted to keep the first one small scale so I've got 2kg of pilsener malt.
I've got some tettanager and some cascade hops.
I've also got a Morgan's Australian Lager Kit sitting around. I was thinking of doing something like Beachbum did in this thread

So I would produce an 8-9l wort using a BIAB mash, split into 2 for boil. To each boil add one of cascade or tettanager for flavour and aroma. The kit will cover the bittering hops, I assume with Pride of Ringwood.

Split the kit into 2 fermentors, add the cascade wort to one and the tettanager to the other and top up each to 15 litres.

Questions:
1. Does this sounds like a good idea, or is it a waste of 2kg pilsener malt and hops?
2. I have heard of someone using POR for bittering and Cascade for aroma/flavour successfully. Do you think POR/Tettanager combo would work?
3. How much flavouring and aroma hops would you add? (keep in mind the target drinker, e.g. father in law drinks Hahn Super Dry, brother-in-law drinks Henninger). Both hops are around %5 AA from memory (check when I get home)

I went and did it. Not a great idea.
Mashing the 2kg of JW pilsener malt was a big success. I got 13l into the boil at 1.04, which gave me 84.7% mash efficiency according to the calculator. Very happy with the BIAB side of things.
After that, splitting into 2 was a terrible move. Twice the work, twice the opportunities to make mistakes. I got a bit lost with volumes on the way so no idea of evaporation rates. I took my OG after mixing with the kit, so no idea how much lost to trub (seemed like a lot).
A great learning experience.
