Sumatra Organic

Grumpy Mule is a specialty coffee roaster based in Yorkshire, UK, turning out kick-ass coffee with a shrewd sourcing ethic and respectful roasting approach. Their lineup spans single origins, blends, and organic options—like the Top Notch Organic Blend with notes of berries and dark chocolate, or the Kick Ass House Blend with caramel and milk chocolate. They emphasize doing coffee right through certifications, environmental care, and support for local farming communities. Customers rave about the smooth, rich flavours and total lack of bitterness. You can snag their beans through their online shop, with a subscription option for regular deliveries, or grab bundles for extra value. Straight-talking Yorkshire coffee with a conscience.
