    Farm to bottle

    We know which room, and which week.

    We grow Lion's Mane and Reishi on our farm in Oswestry; Chaga is hand-foraged from wild birch in the Scottish Highlands. We dry every batch slowly on the farm, send it sealed to a specialist UK extractor who dual-extracts and bottles to our spec, and check, label and release every bottle back in Oswestry.

    II. The Ratio

    1:3, not 1:5.

    More mushroom in every drop.

    The number that matters most on a tincture is usually the one you can't see: the extraction ratio. It tells you how much mushroom went into the bottle in your hand. Most mushroom tinctures are made at 1:5, one part dried fruiting body to five parts finished liquid. Ours is 1:3. That is two-thirds more mushroom in every millilitre.

    What that means for you

    A dense, properly loaded extract, not a lightly flavoured liquid with a mushroom on the label. More of our own Oswestry-grown Lion's Mane and Reishi, and our Highland-foraged Chaga, in each bottle you buy. More mushroom for your money.

    Why it isn't the norm

    A denser extraction is slower, yields less liquid from the same harvest and costs more to make. That is why 1:5 became the norm. For us, 1:3 is the only ratio we are willing to put our name to: more mushroom, made the slow way, by the people who grew it.

    1:3 refers to extract strength: the ratio of dried fruiting body to finished tincture.

    III. Our principles

    More than a wellness brand.We are growers first.

    The functional mushroom category is, for the most part, a global powder trade. Most of what's on a UK shelf is mycelium grown on cereal grain in an overseas factory, dried into a flour that is largely starch by weight, shipped in bulk, white-labelled and pressed into capsules by people who have never met the people who grew it. We do the opposite. We grow the fruiting body ourselves on a certified organic urban farm in Oswestry, dry it slowly on the same site, and know exactly which room and which week every batch came from. Wellness is what the bottle does for you. Growing is what we do to earn the right to put it there.

    01

    First flush only

    We harvest only the inaugural fruiting, the most potent, bioactive expression of the mycelium. Like extra virgin oil, the first press is the truest.

    02

    Grown on our urban farm

    Our urban farm sits in the centre of Oswestry, Shropshire, a working farm with the room and rhythm to grow everything we need. Lion's Mane and Reishi for the tincture range; alongside grey oyster, yellow oyster, pioppino, golden enoki, black pearl oyster, shiitake and a rotating cast of others for chefs, the café bar and what comes next. Chaga, which refuses cultivation, is hand-foraged by a trusted Scottish partner from wild silver birch in the Highlands.

    03

    Fruiting body, never mycelium

    We extract from the fruiting body alone, where the beta-glucans and triterpenes live. No grain fillers. No marketing tricks.

    04

    Certified organic

    From substrate to harvest, every step is organically certified. What enters your body should be as honest as what enters our soil.

    “The first flush is the mushroom at its most articulate - everything we make begins, and ends, there.”

    Paul Murray · Founder & Cultivator

    IV. The Café

    A drinks room in Oswestry.

    Our café is the working library of the brand: a quiet drinks room where tinctures are paired with single-origin coffee, cacao and chai. Theme evenings, and the people who grew the fungi in your cup.

    Overhead view of mushroom-infused drinks at the Shrooma café: matcha and beetroot lattes, espresso, and a cold brew, with mycology books.
