Cast Iron Coffee Roasters operates out of Chichester, West Sussex, sourcing and roasting specialty coffee with a no-nonsense, hands-on ethos. Their lineup runs from single origins like the direct-trade Finca La Colombia from Cafe Lumbus to blends, decaf, and a Black Label Collection for the rare, competition-level lots. They've got a coffee shop in Chichester where you can taste before you buy, plus a barista course if you want to level up your home game. There's a subscription for regular deliveries, and wholesale customers get a workshop invite and La Marzocco gear. Fresh, traceable, roasted to order. Simple as that.
