How do I use green coffee beans in liqueur without harsh grassy bitterness?

Expanded Explanation

Green coffee has herbal, nutty, slightly peppery notes and can get harsh if over-extracted. Lightly crack or coarsely crush (don’t powder), and use higher-proof spirit (50–60% ABV) to pull aroma efficiently with shorter contact. Start with a small dose—10–20 g per liter—and taste daily.

Timing is the biggest lever: 12–48 hours often gives plenty of character, while 3–7 days can become aggressively bitter and astringent. Once you hit the flavor you like, strain immediately and only then add sweetener. If you want more “coffee” while staying smooth, blend a tiny amount of roasted coffee infusion into the green coffee base.

Common mistakes: leaving beans too long, using fine grounds (muddy filtration), and adding sweetener too early (harder to judge extraction). Flavor impact is herbal coffee‑tea, great with citrus peel, vanilla, or cacao nibs—added in micro-doses. Store dark and cool; green coffee notes fade faster than roasted, so drink within a few months for peak aroma.
