John Deboer created this beer layering tool so beer lovers can create these combinations easily at home.
The secret is to have a bottom beer that’s denser than the one on top. A stout and a lager are the traditional combo, but there are lots of variations that balance different flavors, like a cider and stout. With the tool in place on your pint glass, all you need to do is pour slowly.
These layered drinks are often called a “Black and Tan,” but that term is controversial for some because it conjures up a dark time in Irish history. The “black and tan” were British paramilitary troops with uniforms of those colors, and they violently suppressed the Irish a century ago. If you ever find yourself in Ireland, it’s best to use the more respectful term “half and half.”
Whatever you call these combinations, making them is now as easy as enjoying them.
