Using Ground Coffee in Nespresso & K-Cup Machines
Reusable/refillable pods let you brew any ground coffee - including your own - in a Nespresso or K-Cup machine. Here's how they work and what to fill them with.
Pod and capsule machines are built around single-use pods, which is exactly why so many people search for a way around them - "ground coffee for Nespresso machine," "ground coffee for K-Cup," "ground coffee for reusable pods." The good news is this isn't a workaround, it's a well-established product category: reusable (refillable) pods and reusable K-Cup filter baskets are designed specifically to let you fill a capsule-based machine with any ground coffee you like, including your own.
How Reusable Pods Work
A reusable pod is a small metal or food-grade plastic capsule shaped to fit your specific machine - Nespresso-compatible pods for Nespresso-style machines, K-Cup-shaped reusable baskets (sometimes called a K-Cup filter or K-Cup basket) for Keurig-style machines. You open it, spoon in ground coffee, tamp it down lightly, close it, and brew as normal. The machine can't tell the difference between a reusable pod and a disposable one - it just pushes hot water through whatever's inside.
Brands like Ekobrew make stainless steel reusable pods aimed at exactly this use case, and pod-based espresso machines like the Francis Francis X1 (an Illy-designed machine) are commonly searched alongside "ground coffee for pod machines" by people looking to use their own coffee rather than proprietary capsules. We can't speak to the specifics of any one product's fill capacity or compatibility - check the pod manufacturer's own listing for that - but the general mechanism is the same across brands.
How Much Ground Coffee Goes In
Reusable pods are small, generally sized to hold a single shot or single cup's worth of grounds - think somewhere in the range of one to two tablespoons, though exact capacity varies by pod design and machine. It's worth slightly under-filling on your first attempt and tasting the result, then adjusting up or down, rather than assuming a specific gram measurement without checking your particular pod's guidance.
What Grind Size to Use
This is the part people get wrong most often: don't reach for an espresso-fine grind by default. Pod machines generally push water through under lower, more consistent pressure than a traditional espresso machine, and a too-fine grind in a small reusable pod tends to channel - water finds a path of least resistance through the puck instead of passing evenly through it, giving a weak, uneven shot despite a fine grind. A medium-fine grind, a touch coarser than pure espresso grind, is the safer starting point for most reusable pods and K-Cup baskets. From there, go finer only if your shots are running too fast and weak.
Why Bother With Reusable Pods
Beyond the environmental angle (less single-use packaging), the real draw is choice and freshness: disposable pods are sealed at the factory and can sit for months before you buy them, while a reusable pod filled fresh from a bag you control lets you use a blend and roast you actually like, ground and used within weeks rather than however long a sealed capsule has been on a shelf.

A reusable pod or K-Cup filter turns any capsule machine into one that brews your coffee, not just the manufacturer's - the machine doesn't care what's inside the capsule, only that the grind and fill amount are right.
