That's good to know, oldbloke. My wife was diagnosed very young (her elder brother's coeliac too - West Irish roots have something to do with it, apparently) and so hasn't tasted beer other than a fair few Guinness in her wayward teens, and the commercial GF varieties, some of which are ruddy awful, so the GF kit version wouldn't be competing in a taste test with barley/wheat beers. If it approximates a lager flavour and looks golden in a chilled glass on a sunny day I think she'll be happy enough!
Cider's her usual drink, so I'm going to do a Blackrock Cider kit for my second shot at brewing.
As I get more experienced I might well experiment with GF recipes. Do let me know how your Mild goes.
Cheers.
