Cafés in London/Manchester pouring a World-class roaster or a Top roaster.
World-class roaster — recognised at world level — a world championship title or two world finals won with its coffee, or strong recognition from two sides at once, one of them worldwide.
Top roaster — one strong sign — a national title or roasting placing, its people at a world championship, three auction lots, a place on the reference list of great roasters, or five good cafés that pour it.
