While I was in M&S buying that lot for work I also took the opportunity to pick up some of theirs for me for supper. The first one to be broached (to give me inspiration for cooking) is a Sorachi Saison, and to my slight surprise, it's absolutely delicious. Although it's clearly brewed to show off the hop - something called Sorachi Ace, "zesty lemon and orange notes with intriguing hints of spice" says the BS on the bottle - and it's extremely bitter, it's not over-hoppy or over-bitter. I suspect that the malted wheat (congratulations to M&S for listing the ingredients) and the alcoholic strength (6%) go to provide the balance you don't get with the rankest of the American-style beers. It's also brewed by the experts at Adnams, which no doubt helps.
@Marmion wouldn't like it - plain black cap. And since to my eternal regret, Mrs W doesn't drink beer, and since to their shame M&S don't sell a dry cider I had to pop next door to Waitrose for a couple of bottles of Aspall's Premier Cru for her.
