I.
Preheat a saucepan filled with water. Roughly chop the CBD flowers.
II.
In an airtight jar, combine the grapeseed oil and the flowers.
Place your jar in the saucepan to cook the mixture in a bain-marie. Use a cloth to prop up the jar and prevent it from coming into direct contact with the saucepan.
III.
Leave the flowers to macerate in the oil over low heat for 30 minutes. Turn off the heat and let the maceration continue for as long as you like (from 30 minutes up to 48 hours).
IV.
Pour the infused oil into a glass bottle with an airtight seal, filtering it through a sieve.
