I've had Tequila perhaps a dozen times in my entire life... and nearly every time I did I was already drunk on something else before I had the tequila.
Here's the problem, for me anyway... it's not the taste, which to me is not good but not horrible either. It's the God Awful SMELL....it's unbearable.
Now if you can get beyond the smell, (almost an impossible task), more than any other kind of liquor the difference between cheap tequila and expensive tequila is HUGE... so my advice -
If you are a masochist and wish to imbibe Tequila break open your wallet and fork it over for the 'best', (most expensive).
