Sleepytime Lager

The concept here: a black lager with an extra midnight-y nudge in the direction of bed. I’ve made sleepytime beer before, using a more standard ale approach, but this was a chance to experiment with a slightly more complicated mashing process and pretend I’m a real brewer. Proof that I don’t entirely know what I’m doing, however: I fucked up and added some old, ridiculously bitter wormwood from an herbal supply company for an extra relaxing effect, but the clean taste of lager allows little room for error, and I think this recipe is better without that bitter edge, so I’ve fudged and left it out. Otherwise, it turned out fine, taking advantage of an unusually cool May and June here in the UK to ferment and age at room temperature (there’s no cellar). So if you’re a homebrewer with minimal equipment like me, don’t be intimidated by most of what you read about the supposed finickiness of lager yeast. It’ll be fine.

Don’t use too much valerian, because it has kind of an unpleasant odor, but lavender and chamomile are both very nice and go well together.

A black lager with hops and other soporific herbs. Add herbs ~10 minutes before flameout. I did a step infusion mash with a half-hour rest at 132F/55C before bringing it up to saccharification range for another half hour. I didn't use Pilsner malt simply because I didn't have any on hand.
