What Is Grumpy Mule?
Grumpy Mule is a Yorkshire-based organic and Fairtrade certified coffee brand roasted in Harrogate. The distinctive illustrated mule packaging has made it recognisable across UK supermarkets — you'll find it in Waitrose, Ocado, and independent delis alongside the Sainsbury's organic range.
What distinguishes Grumpy Mule from other organic UK brands is the range: instead of one or two blends, they stock several single-origin and blended options at different roast levels. The Ethiopia Yirgacheffe, in particular, is the sort of coffee that belongs in a specialty cafe rather than a supermarket shelf.
Taste Test
Organic Colombia brewed as cafetière: clean, sweet, with caramel and light hazelnut. Not the most complex Colombian you'll find, but easily the best at this price from a supermarket brand. Consistent cup to cup.
Ethiopia Yirgacheffe as V60: this was the standout. Blueberry jam, stone fruit, and a floral finish that lingered. For a natural-process Ethiopian at under £12, this is genuinely impressive.

Not the most complex Colombian available at this price
Yes — all Grumpy Mule coffees are certified organic and most carry Fairtrade certification. The brand is part of Bewley's, an Irish beverage company, but maintains its own sourcing relationships and organic credentials. For UK buyers wanting certified organic coffee at supermarket prices, Grumpy Mule is one of the most accessible options.
Where is Grumpy Mule Coffee roasted?
Grumpy Mule is roasted in Harrogate, North Yorkshire. The roastery is part of the Ringtons group, one of the UK's oldest tea and coffee merchants. Despite being distributed nationally through major supermarkets, the roasting remains in Yorkshire.
Which Grumpy Mule coffee is best?
The Organic Colombia is the most popular and versatile — a medium roast with caramel and hazelnut notes that works well as espresso, pour-over, or cafetière. The Ethiopia (natural process) is the most interesting cup for specialty fans — jammy, fruity, complex. The House Blend is the best everyday option for those who want something reliable and consistent.
