Waitrose, the rotten barstewards, have stopped selling Bratties . But I've tracked some down in the Oxford Tesco - a fearful place infested with lower orders from Blackbird Leys....
Our local germanic-owned price-efficient outlet does a very good range of bratties. The "lower orders" are offset by '16 plate Mercs and Range Rovers so it can't all be bad.
BTW, they also do mini-kegs of weiss at the moment.
