You've probably been to that party. The one where it ends up being not quite the party you were expecting? You're all geared up for a evening full of chips and dip, pizza, laughs and loud music, and tall frosty beers. Instead, you show up and there's canapé, light jazz, and pinot grigio. Not that there's anything wrong with a chill time with friends, but not when you were expecting brews and bros.
Hedge your bets like a pro - bring along a beer stein with a built-in wineglass! Too confusing? Lemme 'splain. This beer stein is double-walled, but instead of the inner-wall of glass being shaped like the outside stein, it's actually shaped like a wineglass. Now it looks like you're kinda sorta drinking a glass of wine.
Conversely, if you want all the fun of an Octoberfest with the charm and sophistication of a gallery opening, you can drink your Sauvignon Blanc with gusto and enthusiasm from a comfortable beer stein. With that kind of versatility, you're prepared in any eventuality.
