Hartmann Estate Geisha

Sea Island Coffee are rare-origin specialists based in the UK, sourcing from over 30 of the world's most unusual coffee estates — think St Helena, the Galapagos, Fiji, and wild Kopi Luwak from Sumatra. They're not your everyday roaster; this is the place you go when you want a Jamaica Blue Mountain that Napoleon would recognise, or a low-caffeine Coffea Racemosa that sells out every year. They roast single origins to order, offer whole beans, ground, and Nespresso-compatible pods, plus a subscription that knocks 10% off. The vibe is explorer-meets-purist, backed by a 4.7 rating from a loyal crew of fellow obsessives. No cafe of their own — just the beans, beautifully bagged or tinned, shipped free in the UK.
