Long before hops found their way into beer, they were quietly doing something else entirely. Something slower. Something nocturnal.
Humulus Lupulus — the common hop plant — has been cultivated across Europe for over a thousand years. Most people associate it exclusively with brewing, and fair enough. But the relationship between hops and human rest predates the pint glass by centuries, and it's one of the more charming stories in European herbal tradition.
The hop fields of old Europe
The earliest documented use of hops as a calming agent comes from medieval Central Europe, where Benedictine abbeys grew hop gardens not just for brewing but for their medicinal properties. German and Czech herbalists recorded its use as a treatment for restlessness and nervous agitation as far back as the 9th century.
But the most compelling evidence came later, and from an unexpected source — the hop harvest itself.
Workers picking hops by hand across the fields of Bavaria, Bohemia, and Kent reported an unusual drowsiness that couldn't be explained by the physical labour alone. They tired faster, slept longer, and woke more slowly than workers in other harvests. Herbalists of the time noted this carefully. The plant, it seemed, had opinions about rest.
Hop pillows — a folk tradition that still exists
Across rural Germany, Austria, and the Czech Republic, the tradition of filling small pillows with dried hops flowers and placing them inside a pillowcase persists to this day. The gentle, bitter-green scent released by the plant as you lie on it was believed to encourage sleep. Pharmacies in Bavaria still sell hop pillow sachets alongside more conventional sleep aids.
Whether the effect is primarily aromatic or something more complex is still debated, but the tradition has survived long enough to suggest it's doing something right.
So what's actually happening?
Modern research points to a compound called 2-methyl-3-buten-2-ol, which forms when the alpha acids in hops oxidise. This compound has demonstrated mild sedative properties in studies, appearing to interact with GABA receptors — the same pathway involved in regulating calm and sleep in the central nervous system.
Interestingly, this is also why hops work differently in a tincture than in a pillow. When taken orally, the active compounds enter the system directly. When inhaled from a hop pillow, the mechanism is different but the folk observation — that hops and sleep are old friends — holds up either way.
And the beer connection?
Hops were added to beer primarily as a preservative and to balance the sweetness of malt. But there's a reason a hoppy pint makes some people sleepy in a way that, say, a glass of wine doesn't quite replicate. The sedative compounds are present, albeit in small quantities after the brewing process. It's not a medicinal dose. But it's not nothing either.
The Germans have a word — Bierschlaf — meaning beer sleep. The nap after a quiet afternoon pint. Hops have always been in on that particular joke.
Hops in Noddfa Nos
We use a Hops Flower Tincture in Noddfa Nos because a tincture preserves and concentrates what the dried flower offers, without the beer. Two pumps in warm milk at bedtime. The Bavarian farmers would probably approve.
Nos da.
