How to make hash (dry-sift basics)

Hash is concentrated trichomes — the resin glands that hold most of the cannabinoids and terpenes. The simplest, solvent-free method is dry-sift: separating those glands with cold and a fine screen, then pressing them.

This is an educational overview. Solvent-based extraction (using butane, etc.) is dangerous and is deliberately not covered here.

The easy route: your grinder's kief catcher

Many grinders have a fine screen and a bottom chamber that collects kief (loose trichomes) over time. That powder IS unpressed hash. Collect it, then press (below).

Dry-sift with a screen

1. Freeze your flower and a fine mesh screen (a clean silkscreen or a fine kitchen sieve) for ~30 minutes — cold makes trichomes brittle and easy to knock off.
2. Place the screen over a clean, smooth surface (a mirror or glass works well).
3. Gently roll and tumble the cold flower across the screen. Fine blond powder falls through — that's your sift.
4. Don't overwork it; the whiter and finer the powder, the purer it is. Greenish dust means plant matter is getting through.
5. Gather the powder with a card.

Pressing it

1. Wrap the powder tightly in parchment paper.
2. Apply gentle warmth and firm pressure — a warm (not hot) bottle rolled over it, or pressing between warm palms.
3. It binds into a small slab as the resin softens and sticks together.

• Quality depends entirely on starting material and how clean your sift is.
• Store cool and dark; heat and light degrade it.
