Slow by design

We pour sixty jars at a time. Nothing is extracted, nothing is rushed, and everything that is left over goes back into the garden bed it came from.

  • Fermented, not extracted

    Moss and fern sit in glass for nine weeks. It is slow and quiet, and it is why the mist feels the way it does.

  • A refill loop

    Post the empty jar back in the pouch it came in. We wash it, refill it and send it out again, up to twelve times.

  • Soil-safe all the way

    Paper labels, compostable wrap, no microbeads, and a formula that rinses into a garden bed without complaint.

How a jar is made

From the north slope to your shelf, and back.

  1. Gather

    Moss and ferns come from the farm’s shaded north slope, a few handfuls at a time, always leaving the colony.

  2. Ferment

    Nine weeks in glass at a steady 18 degrees, tasted, smelled and logged by hand every Friday.

  3. Blend

    Small batches of sixty jars. Each one is labelled with the date it was poured and the tank it came from.

  4. Grow back

    Return the jar, plant the packaging, repeat. The loop is the product.

Join the grove

A monthly note from the greenhouse: what is fermenting, what is flowering and when the next batch of sixty is poured. First access to every small drop.
