as a bartender, each scotch and whisky command its own
respect, we do not mix them up, what we mix is usually with gases
drink such as tonic, soda, orange, coke, lime etc etc...to make the
drink sparkling and also more smooth.
Mixing of hard liquor is the same, but you lost the taste of its
brand, johnny as about 45% alcohol level, same goes to Jim Bean,
whereas martel can command up to 48% and 52%, you mix them up, you
will get the same level. No problem in mixing them up, you will get
high same as not mixing them up. But you lost the maker's taste and
to a disciplined bartender like me, it is a disrepect of the
maker. Hard Liquor command a little more respect.
