I'm fairly sure I'm in a minority on this among beer drinkers, but I do like a decent whack of sulphur in my beer. The legendarily hard water of Burton-on-Trent historically gave a sulphury character to the beer brewed by Bass, Allsop's, Ind Coope and Marston's among others. People say that this so-called "Burton snatch" is far less prominent in the likes of Marston's Pedigree than it used to be, but in the bottle it's still pleasantly noticeable (I haven't drunk it on draught recently). Can't say I can get it in Worthington White Shield though.
I've also detected sulphur in certain Franconian beers, though I shall have to look into which areas of Franconia (if any) have hard water.
There's a passage in one of Michael Jackson's books where he is tasting a Japanese microbrewery's beer and remarks that it's rather sulphury. The head brewer replies "Yes, that is intentional. We want the beer to smell as fresh as a bath-house." Which just goes to show that there's also an element of cultural context involved in whether you find it pleasant or not.
I wanted to make a souped-up beer inspired by the famous Burton bitters. For me these are about being about to taste the minerals in the water, about an intensely dry bitterness and a nice deep red colour, but not too dark (it's a pale ale after all). It's not really about hop aroma or full, malty body, although a bit of toffee is not bad.
So that means adding a stupid amount of gypsum to the brewing water, hops mostly for bittering, and crystal malt.
5L water heated with 1 tbsp gypsum
200g crystal malt
1800g pale malt
Mash at 68º for 180 minutes (they did long mashes in the 18th century … oh, all right, I went back to bed and fell asleep)
Sparge with 4L @ 80º and another 1 tbsp gypsum in the sparge water.
Boil for 90 minutes.
30g Challenger (5.1%) 90 minutes
10g Challenger 0 minutes
The wort doesn't taste sweet because of all the minerals and hops, but the OG is right at 1050.
It wouldn't be right without a Burton yeast, so I kidnapped the sediment from a bottle of Worthington White Shield and cultured it up. I was very impressed with how well the yeast recovered.
The temperature according to my thermometer is still under 23ºC, but I don't believe it. We shall see – the last couple of brews seemed to do quite well despite the heat in my flat.
