A glass of bourbon after a grueling day can be a refreshing thing. So can a nightcap out with old friends. Choosing the right bourbon is half the battle. Fortunately, there’s an app for that. Distiller is like having a whiskey aficionado living inside your iPhone or iPad. You choose the setting of where you’ll be enjoying your drink (on the patio, at a bar, by a fireplace, etc) and your taste preferences, and Distiller creates a tailored list of recommendations, complete with tasting notes and a few other bourbons that may be up your alley. Not a bourbon specialist? You don’t have to be. You’ll have Distiller. It’s free in the iTunes store.
