Re: What's your favorite Beer/Liquor?
I don't think there's any hard alcohol I could say I'd be comfortable drinking in all situations. As for beer, I'd be totally embarrassed to be seen drinking Heineken. Beers such as Bass or Sam Adams are probably the beers I could most drink in any situation - that isn't to say they're my favorite beers though. But they're beers you don't get questions about, and are good.
Grey Goose is a great vodka for certain things, but it's terrible in things like martini's... it just has a certain strong taste to it - not like an alcoholy taste, but its flavor. I've discovered Three Olives Vodka is great for martini's. But of course, martini's are not a thing that you could drink in all social situations.
I'm a big fan of whiskey's, and you can drink those in more situations than things like martini's... a good 12 year whiskey like Red Breast is nice...
