Yikes. 40% is strong enough for me. But thanks for the info. I'll be sure to check the percentages on any new ones I try.Most Scotch is around diluted by the distiller to around 40% alcohol. However, "cask strength" is undiluted and can be between 60-65% alcohol. "Cask strength" is the only Scotch I will add any water to. If you want something stronger, try "still strength". That is 70% or more.
