The case for the slow second crack

Most roasters chase the cleanest light roast they can pull off. After a winter on the drum in Trondheim, I’m no longer sure that’s the right ambition.

I spent two weeks last winter rewriting a roast profile I’d defended for almost four years. The bean was a washed Kochere lot we’d been buying since 2022, and I had always pulled it just past first crack — a clean, almost floral cup. In Trondheim, on a borrowed Probat, I let the same lot ride forty seconds longer. The cup that came out was darker, rounder, and stranger. It tasted, for the first time, like a decision.

What we trade away when we chase clarity

The third‑wave orthodoxy — the one I helped repeat for most of a decade — treats development time after first crack as a kind of debt. In practice, what I’ve found at the cupping table is messier: the lots we pull early are legible, but they’re also interchangeable. Push the same green into the slow second crack and the cup stops being a tasting exercise and starts being a drink — something with body, with finish, with the kind of warmth that survives a long walk home in February.
