I know you’re trying to relax, but I’m still going to make you do some math. Ready? Here’s my favorite equation: beer = malt, hops, yeast, and water. Understanding that equation helps you order the right beer in the right circumstance. You in the mood for the flavors of toast or chocolate? Then you want a malt-forward beer like Chuckanut’s award-winning Dunkel. Or perhaps you want to annoy your evolutionary ancestors by opting for the taste of bitter fruit. Then you want a hoppy beer like Aslan Batch 15. Or maybe you want to tantalize your taste buds with the spiciness of pepper or clove. Then you want a yeast-forward beer, like Wander Wild Warehouse. But what about that last ingredient – what about water? Well, you want your beer to be in liquid form, right? Then water is the key. But water plays a more interesting role in beer than simply making it a liquid. And today of all days, it’s appropriate to pay homage to the role of water in brewing, because water is the reason why we drink stout on St. Patrick’s Day.
