Drinking on a budget is a balancing act. You want something that tastes good (there are loads of quality affordable wines out there), but you also want something with sufficient alcohol content to keep you at a nice buzz. This is easy enough at the bar, where you order a drink and can reasonably expect that drink to be a standard serving size, but it’s harder out there for the party thrower and home entertainer because alcohol bottles don’t say how many servings they hold.
