Winter warmers are a catch-all category for a number of different cold-weather brew styles, but you can expect most to fall between 6-10% alcohol content. The elevated ABVs are responsible for the style’s “warming” qualities; alcohol is a type of vasodilator, meaning the capillaries at your skin’s surface open (or dilate) and brings more blood to your body’s exterior — hence the warming sensation; it’s the same reaction you feel when eating especially spicy foods like hot peppers. The effect is found in other high ABV beers, but the winter warmer’s holiday spices and heavy quality really encourage you to snuggle up on a long winter’s night.
