Black Donkey Intenso review: a robusta kilo sold on strength

Black Donkey Intenso is a cheap, strong espresso kilo, and the fact that decides whether it suits you is printed on the listing: 80% robusta, 20% arabica. Robusta brings caffeine, body and crema, and it brings more bitterness than arabica does. If you drink espresso or milk drinks and want a coffee with some force behind it, 31p a cup is a fair price for that. If you want a cup that is sweet and pleasant black, the ratio is working against you.

What 80% robusta does to a coffee

Almost everything worth knowing about Intenso follows from its ratio. Robusta, Coffea canephora, carries nearly twice the caffeine of arabica on the standard figures (around 2.7% of the bean against 1.5%), brews strong, full-bodied and earthy, and is usually more bitter. It is also cheaper to grow, which is part of how a kilo lands at £17. Good robusta has a long-standing job in Italian espresso blends, where it is there for body and a thicker crema.

Put four parts robusta to one of arabica and you get a coffee built from that list. On those textbook averages an 80/20 bag holds roughly 60% more caffeine per gram than an all-arabica one. Black Donkey's own tasting line reads spicy and intense, with toasted bread and a lingering cocoa aftertaste. On their in-house strength chart it scores 8, where the 100% robusta Devil's Roast scores 11 and the arabica Delicato 7. That scale is Black Donkey's rather than an industry one, but it places Intenso fairly: strong, and not the strongest thing they sell.

What the listing says, and what it leaves out

We could not find a website for Black Donkey, so the Amazon listing is the fullest statement of what is in this bag. It is more specific than most value brands manage about the blend, and vaguer than it first looks about origin.

Read the two origin rows together. The five-country list sits in a bullet about Black Donkey's beans in general. The line that is specifically about Intenso, in the comparison chart further down the same listing, says Brazilian arabica and natural robusta, and gives no country for the robusta. Since the robusta is 80% of the bag, the honest summary is that you know the species, the roast and the country it was roasted in, and not much else.

The listing never mentions a roast date. It promises that the valve keeps the beans fresh for 24 months after packing, which tells you how long the bag stays saleable rather than how recently it was roasted. Why a roast date tells you more than a shelf life

Espresso, milk and bean-to-cup

This is an espresso and moka pot coffee first. The things robusta brings (body, crema, caffeine) are the things that show under pressure and survive steamed milk, which is why Italian roasters put it in espresso blends at all. In a cappuccino or a flat white, a robusta-heavy shot is more likely to hold its own against the milk than a mild arabica is. Black Donkey's grind guide covers every brewer, but black, from a cafetière, is where the extra bitterness has nowhere to hide. If that is how you drink coffee, most of this page is an argument for a bag with more arabica in it.

Bean-to-cup owners have one more thing to check. De'Longhi tell owners of their automatic machines to avoid beans that are too oily, caramelised or coated, and surface oil is a dark-roast trait: it rises as the roast goes darker. Intenso is dark, which counts against it. Its ratio counts for it. Green robusta holds around 10% lipids against roughly 15% for arabica, according to a published review of coffee bean lipid research, so a robusta-heavy dark roast has less oil to push to the surface than an all-arabica bean taken to the same colour.

That is a tendency, not a guarantee, and nobody has reported on how these particular beans look out of the bag. So look when yours arrives. If they are visibly shiny or leave a film on your fingers, keep them out of an automatic machine's hopper.

Who has reviewed it: nobody we could find

We looked for anyone independent who has brewed this coffee: blog reviews, Reddit and UK forum threads, YouTube, deal sites. What turned up was resellers repeating the listing copy word for word. That is a finding in its own right. Every flavour word on this page is Black Donkey's, and the rest is arithmetic and the chemistry of the two species.

The listing carries plenty of buyer star ratings, and this site does not treat those as evidence. So treat a kilo of Intenso as a bet on a specification rather than on a reputation. At 31p a cup it is a cheap bet, and the specification is at least unusually candid about the robusta.

What it costs, and how to pay less

At 31p a cup on an 18g dose, Intenso costs about half the 63p median for whole bean coffee on this site. That puts it level with the cheap end of the Italian-style espresso kilos rather than below them: Lavazza Qualità Rossa and Black Donkey's own Devil's Roast are both 32p in our data.

Subscribe & Save was taking 5% off the listing when we checked at the end of September 2026, which brings the kilo to about 29p a cup. That is the only direct discount we saw.

The bigger saving is not letting the end of the bag go stale. A kilo is about 55 doses. Black Donkey say it tastes best within four weeks of opening, which a two-cup-a-day household will just about manage and a one-cup-a-day drinker will not. If you are the second, tip half the beans into an airtight container the day the bag arrives and leave that container shut until the bag is empty.

Who should skip it, and what to buy instead

Skip it if you drink coffee black and like it sweet, because four parts robusta is not built for that. Skip it if you want to know where your coffee was grown. And skip it if you would rather buy something other people have already vouched for, because at this price there are kilos with far more written about them.
