Taste of what? 100% alcohol? Pale lager? Dark lager? White wine? Red wine? Liqueurs? Vodka? Tequila? Whiskey? Cognac? Brandy? Numerous cocktails? Ciders? Too many different kinds to put them under one umbrella.
Yeah I dislike the taste of pale lager but adore glass of fine red wine.
3 options here:
This guy is an awkward teenager, who is not getting invited to the cool kids' parties. He took a sip out of an unfinished bottle, that his parents left when they had guests last Christmas.
Option two - he is one of them grown up basement dweller types. Only drinks cola and such, saving his brain cells and sperm quality for the bright never-to-come-future use.
Last option - a very focused, boring and dry guy. Has a plan for life. Clean home. Clean shave. Bank papers and bills are foldered and signed, etc.
