i have possibly mentioned this :
1 unit Whiskie . 1/2 unit cold water
I find the water cuts down on the EtOH burn
which is not only harsh , but interferes w the euro-transmission
of whiskie's flavors
some tingle for sure , but not a Big Burn.
BTW : the @duvel recommended whiskey glasses

are very nice. the shape concentrates the aromas very pleasantly.
much better than Rotary , which is highly unusual
