Description
Built for Belgian dark strong ales, with clove, pepper and a tart phenolic edge that deepens the warmer it runs. The published working range is narrow and hot, so plan for temperature control at the top end. It copes well with high-gravity worts and finishes dry enough to carry rich malts or fruit additions.
