2. Whiskey Sour

While a Whiskey Sour is typically tart and refreshing, adding a dash of bitters really brings it all together.

A few dashes of bitters can balance the sweetness and enhance the richness of the whiskey, taking this drink from good to great. If we’re being honest, a whiskey sour without bitters is like a Sunday roast without the gravy. Sure, it tastes good but it’s just not the same.
