Naki RoastIn defence of Robusta (and why The Mule kicks)
Walk into enough specialty coffee shops and you pick up the rules. Single origin or nothing. Light roast or you're a philistine. And whatever you do, don't say Robusta out loud. It's the bean that built instant coffee, the one the snobs treat like a swear word.
We put a quarter of it in The Mule on purpose. Here's why.
Why a mule?
A mule is a hybrid. Donkey crossed with horse. It's not glamorous, and it's not trying to be. It's the animal you want when there's actual work to do: strong, sure-footed, hauls the load all day without complaint. Stand behind one and it kicks.
That's the bag. Seventy-five percent Arabica for the flavour, twenty-five percent Robusta for the punch. Four origins in one cocktail: Colombia, Mexico, Brazil and India. A workhorse you can pour every morning, with a bit of kick in the back end.
The bean nobody brags about
What the snobs leave out: Robusta isn't some fringe ingredient. It's nearly 40% of all the coffee grown on earth. It's in a fair chunk of the espresso you've had in Italy. It built the instant aisle. The world drinks oceans of the stuff. It just doesn't get printed on the label.
What Robusta actually does
Arabica gets all the love, and fair enough. It's where the sweetness, the fruit and the bright notes live. But Robusta isn't a cheap pad-out. It earns its quarter of the bag.
| Arabica | Robusta | |
|---|---|---|
| Caffeine | ~1.2% | ~2.2% (close to double) |
| In the cup | sweet, fruity, bright | earthy, bittersweet, dark chocolate |
| Body & crema | lighter, finer | heavier, thicker crema |
| The plant | high, fussy, delicate | low, hardy, stubborn |
In the cup that does three jobs. It's where The Mule gets its kick, close to twice the caffeine of a straight Arabica shot. It's where the crema comes from, that thick golden layer on a good espresso. And it lays down a bittersweet, dark-chocolate backbone that doesn't wash out the second you add milk.
"But isn't Robusta harsh?"
Bad Robusta is. So is bad anything. The rubbery, burnt-tyre reputation comes from the cheapest beans going: picked unripe, over-cropped, roasted to charcoal and freeze-dried into a jar. That's not the bean's fault. That's the bottom of the barrel.
Roast it like you mean it and it's a different animal. There's even a grading standard for the good stuff. The Coffee Quality Institute scores "fine robusta" on the same 100-point scale as specialty Arabica, and 80-plus earns the badge either way. We're not burying ours under a scorched dark roast. It's in there because we want you to taste it.
The 75/25 call
Why a quarter and not half? Because a kick is a kick. Past a point the Robusta stops being the backbone and starts being the whole conversation. Twenty-five percent is the sweet spot: enough for the punch and the crema, not so much that it bulldozes the chocolate-and-nut sweetness the Arabica brings.
Our Robusta leans on India, where about 70% of the crop is Robusta and they've been growing it for well over a century. The Arabica does the talking through Colombia, Mexico and Brazil. We slapped it together and hoped for the best. Somehow it worked.
Where it shines
The Mule was built for milk and built for mornings. Pull it as an espresso and the crema and body cut clean through a flat white instead of vanishing into it. Run it through a plunger or a moka pot on a slow Sunday and the bittersweet edge keeps it honest. And on a proper early start, a dawn shift or a drive around the mountain before the cloud lifts, the kick is the whole point.
It's not a delicate washed Ethiopian, and it's not pretending to be. It's the cup you reach for when you need the coffee to actually do something.
One bag, one roaster.
Like everything here, The Mule is roasted in small batches and hand-stamped with its batch and roast date, so you always know how fresh your bag is. We roast it and get it to you as fresh as we can: that's the whole reason we do this ourselves. Give it a week or two off the roast to settle into its stride. Right now it's the one bag awake on the lineup while the others sleep between batches.
If word got to you, grab a bag of The Mule before the roaster goes quiet again.
Where this comes from: the Coffee Quality Institute on fine robusta, the International Coffee Organization on how much of it the world grows, and Coffee Board of India figures on who grows what. We just roast it.
