If you’re a beer drinker, you probably have had, and have enjoyed, Delerium Tremens (the beer, not the horrific side effect to alcohol withdrawal).
This is a Hail Mary approach for dad, as it’s expensive, high alcohol, comes in a wine-bottle-sized-bottle, and has a funny non-English name.
It’s a big risk that your dad might immediately shoo-shoo it, but if he doesn’t he’ll get one of the best Christmas beers on the market, and you’ll be able to buy Delerium Tremens bottles as last minute Father’s Day presents that dad’ll actually like.
