Asketh And Ye Shall Receive

[Kai]

I hadn't used BB Pils malt for ages but got a sack in the last bulk buy and did an ozzy lager with Danish yeast, etc. I went up the street for my once-in-three-months pokies session and had a couple of schooners of XXXX heavy as first beers of the day, got home and pulled and ozzy and WHAM - instant mouse plague!
Don't mind it so much, it's a sort of characteristic of the beers.

it's funny, I know exactly the character you are talking about, but I have generally associated it was CUB's yeast strain as I've never noticed it so strongly in any other mainstream aussie lager.

makes sense that the base material for eau de mouse has to come from the malt though.
