Totally untrue. Before Burton earned its fame for PA and IPA, it was known for Burton Ale which was a big malty beer.I would have thought you would want a more balanced water profile, with less sulphate than a Burton water profile. Old ale favours a malty rounded taste which would require more chlorine and less sulphate.
As a guess I'd go something like Ca 100ppm, Mg 5ppm, Na 25ppm, Su 50ppm, Cl 50ppm, Bicarbonate 120ppm. I'd try to keep the sulphate and chloride levels balanced.
So what would you recommend?Totally untrue. Before Burton earned its fame for PA and IPA, it was known for Burton Ale which was a big malty beer.
The problem is that the lore that sulfate makes beer 'bitter' is false. Sulfate makes a beer's finish drier...and when a beer has much bittering and hop flavor, it comes through to the drinker stronger. But, it doesn't make the beer more bitter. If there isn't much bittering in the beer, the effect of sulfate is just its drying of the finish. For a big, malty beer that could potentially be cloying, sulfate can help. I brew my Scottish beers with about 75 ppm sulfate and they are pleasingly malty and finish acceptably dry.
While I won't recommend going all the way to a Burton profile, I will say that sulfate does have a place in malty beer brewing.
It's a recipe I designed myself. I'd give you it but it's not exactly tried and tested!I haven't gotten into water chemistry yet but from reading about the different profiles on brewers friend it looks like the Edinburgh profile is good for malty beers in general.
do you have a particular recipe in mind? I've been wanting to brew an old ale also & am leaning toward an Avery old jubilation clone. I freaking love that beer...
I haven't checked the math on that profile, but you do need to adjust for the weight of each ion, i.e. it's the summed charges that must balance, not the weights of the ions carrying the charges.Totally unrelated, but here's a beginner's question: can anybody tell me where the extra cations are? I count 160 ppm of positive charge and 320 of negative. Or are ppm by mass and not number?
