ESE pods, the standard that survived

What ESE actually is

Easy Serving Espresso: a paper pod 44 mm across holding about 7 g of ground coffee, tamped at the factory, with the grounds sealed between two layers of filter paper. The standard was published in 1998 and deliberately left open, so anyone could make pods and anyone could make machines that take them.

That is the whole difference with a capsule. A capsule is a system owned by somebody. A pod is a size.

What it does better

Waste. Paper and coffee, both compostable, with a small foil sachet to throw away. No aluminium, no plastic shell, no recycling scheme to sign up for.

Dose. Seven grams against five. Not a double, but noticeably more coffee than a capsule, which shows up as more body.

Machine choice. Any machine with a pod basket takes any brand of pod, which includes a lot of ordinary portafilter machines. You are not tied to a catalogue.

Price. Typically 15 to 25 cents, against 35 to 50 for a capsule.

What it does worse

Freshness. A paper sachet is a weaker oxygen barrier than sealed aluminium, and pods are usually bought in boxes of fifty or a hundred that then sit open in a cupboard. Most of the disappointment people report with pods is stale coffee rather than the format.

Choice of roaster. The specialty world skipped pods almost entirely. The selection is Italian, traditional and mostly medium to dark.

The cup itself. Seven grams pre-tamped at a factory into a soft paper puck does not extract like 18 g you ground four minutes ago, and it never will.

Who should still use them

Someone who has a pod-capable machine, drinks one or two a day, wants no ritual and no plastic, and buys small boxes often. In that situation an ESE pod is the most sensible convenience format on the market, and it has been quietly true for twenty-five years.

Someone chasing the best possible cup is in the wrong aisle, and that is fine: the format never claimed otherwise.
