Question about % and dilution
Hi - this is probably a very basic question but am wondering about the relation between bottling percentage and dilution.
I was hearing and reading a lot of praise for high ABV rums - which I first assumed was wanting more of an alcohol kick - but is it more about flavour and dilution?
If barrel strength is 60+% then any spirit bottled at 40% is diluted with water by at least a 3rd..?
Is that right? Is the preference for higher ABV mostly that that it's less diluted?
Are there significant steps up in flavour even at say - 40% vs 43% or 46%. I imagine it would take quite a bit of extra water even to get something from 46% to 40%.
