What Grumpy Mule sells, what it costs against the rest of the market, and who should buy it.
This is an assessment of Grumpy Mule as a brand rather than a live price list — for current prices on every product, the Grumpy Mule hub is the page you want. Here we look at how the range is shaped, where it sits on value, and what we would buy instead.
Live prices for every Grumpy Mule product are on the Grumpy Mule brand page. This review is the analysis that sits alongside it.
The range
Grumpy Mule sells whole bean and ground in the UK. We currently track 11 products, in 500g, 1.2kg and 200g. A brand that spans several formats is usually worth judging format by format — the same name can be excellent value in one and poor in another.
What Grumpy Mule coffee costs
We track 11 Grumpy Mule products, spanning £0.24 to £0.59 per cup — a 2.5× spread within one brand. The cheapest is Kick-Ass House Blend Whole (500g); the most expensive is Honduras La Labor Organic (200g).

|---|---|---|---|---|
| Kick-Ass House Blend Whole | whole bean | 500g | £0.24 | £13.20 |
| Peru Café Feminino Organic | whole bean | 500g | £0.45 | £24.88 |

| Honduras La Labor Organic | ground | 200g | £0.59 | £33.00 |
Pack prices run from £5.50 to £33.95. As always, the pack price is the least useful number here — the per-cup column is the one that compares.
Best value in the range
Kick-Ass House Blend Whole is the strongest value Grumpy Mule currently offers: at £0.24 per cup it sits about 49% below the median cup price for whole bean coffee across everything we track. That is a comparison against the whole market, not against Grumpy Mule's own list prices.
Who it suits
- Home espresso and cafetière drinkers, if the large-format bags are within your six-week window.
- Anyone comparing against supermarket own-brand on price per cup rather than on the label.
- Anyone who wants a repeatable cup rather than a rotating single origin.
Value for money
On our own test — cost per cup against the median for the same format — Grumpy Mule has at least one genuinely strong product in the range. That is a better result than most brands manage, and it is concentrated in the larger pack sizes.

Alternatives worth comparing
Before buying, put Grumpy Mule next to the wider format list. The comparison hubs sort every brand we track onto the same per-cup basis, which is the only way to see whether a brand premium is buying you anything.
