I'm a fan of almost every type of alcohol (perhaps that's a problem?) and agree there's no "best" option.

That said, I don't think your lemon juice example holds up - many of the most enjoyable things in life don't come naturally, but that doesn't mean you shouldn't try to acquire the taste for those things. Great alcohol, great food, great sex - most are not a "natural" taste growing up, and you can't fully enjoy them until you've acquired that taste. Having a dark drink on the rocks or with a splash of soda is definitely a great way to acquire the taste - and unlike lemon juice it's actually very enjoyable.
