Hey? This bit of the thread got caught in an "off subject" transporter beam? I want one of them!
A couple of mistakes in your original post:
One, you might be complimenting a Brit you don't know.
Two, you're suggesting to a Brit watering down beer.
Both result in said Brit being very suspicious! In the case of "one" you get a flippant reply relating to "equestrian urine" (well, I had to get something in related to that choice of words). As for "complimenting a Brit you don't know, I can help a bit there; if I appear to be a bit of a head-case ... that's because I is! "Two"; I like to think I've never drank watered-down beer, but I probably have without knowing. Beer gets watered-down before fermenting ("parti-gyle") but, if it happens after fermentation, it's not advertised as being done. And I never do it, so can give no advice. I'm sure it can be, but surely it would mess up the "balance" of the beer so you'd know it was done?
Well, actually, I was looking for a way to "calc" for a certain ABV (after water addition on a done beer).
That question was answered by other than you, in a reasonable manner by @balrog -Thanx!
I never intended to insinuate that Brits water the beer, Sorry if I came across that way.
I agree, the target beer would have to be somewhat viscus to survive watering down to have body afterwards, as well as over the top "malt flavorful", hoppy, and with yeast expression to be anywhere memorable after even one glass.
These items are not what amylase condone to a brew of any kind, however it does remove calories and I'm sure this is what the BMC do to the "light" beers.
