Bulk Ground Coffee

Ground coffee is the format most often specified loosely and most often disputed on arrival. Almost all of that traces back to one misunderstanding about what a grind setting actually describes.

Quick answer

Ground coffee may be supplied in bulk where the destination cannot grind or the application requires it. Grind is specified as a target application plus an agreed reference sample, not as a single number, because every grinder produces a distribution of particle sizes rather than one size.

A grind is a distribution, not a number

No grinder produces particles of a single size. It produces a spread — a large population around the target, plus fines at the bottom end and boulders at the top. Two grinders set to the "same" medium grind can produce meaningfully different distributions, and the fines fraction in particular changes extraction behaviour sharply.

This is why "medium grind" on a purchase order is not a specification. It names a region of a curve without saying anything about its shape, and it gives neither party anything to measure against when a delivery is questioned.

Grind ranges by application
ApplicationGrind descriptionWhat tends to go wrong
EspressoFineSmall changes in distribution move extraction time significantly
Moka / stovetopFine to medium-fineOften confused with espresso grind in specifications
Filter — drip and batch brewMediumThe broadest category and the most loosely specified
Pour-overMedium to medium-coarseFines cause the bed to stall
French pressCoarseFines pass the mesh and muddy the cup
TurkishPowder-fineRequires a purpose-built mill, not a fine setting on a standard one
These are indicative ranges for orientation. The contractible specification is the reference sample plus the stated application, not this table.

How to specify grind so it holds

  1. 1State the application the coffee is going into, and the equipment if it is known.
  2. 2Agree a reference sample of the actual grind, retained by both parties.
  3. 3Where either side has particle-size instrumentation, record the distribution and the method used to measure it — sieve stack and mesh sizes, or laser diffraction. The two methods do not produce comparable numbers.
  4. 4State the acceptable variance against the reference between production batches.
  5. 5Confirm the packing, which for ground coffee is not a separate question — see below.

Packing has to work harder for ground coffee

Grinding exposes an enormous internal surface area to air, and it releases much of the retained CO₂ at once. Both effects run in the same direction: ground coffee stales faster than whole bean, and it stales fastest in the days immediately after grinding.

  • Barrier material rather than plain kraft — aromatics and oxygen both move through paper.
  • Valve, flush or vacuum, because passive sealing alone does not hold a useful shelf life.
  • Shorter planned transit and stockholding, built into the shipment schedule rather than discovered later.
  • Grind-to-pack immediacy — the interval between grinding and sealing is itself a specification item.

Availability

Bulk roasted and ground coffee is supplied subject to product specification, origin availability, roasting capacity and commercial agreement. Nothing on this page is an offer or a confirmation of stock — availability, lead time and minimum quantity are confirmed per enquiry.

Frequently asked questions

Can you match a grind from a sample we send?
A physical sample is the most reliable basis for agreeing a grind and it is what we ask for. Whether a specific distribution can be matched depends on the mill, and it is confirmed rather than assumed.
How long does ground coffee keep?
Considerably less time than whole bean, and the figure depends almost entirely on the packing. Barrier material, valve or gas flush, and the interval between grinding and sealing matter more than the roast degree does. It has to be settled before a shipment window is agreed.
Do you supply ground coffee for food manufacturing?
Ground and roasted coffee as a manufacturing input is a legitimate application and is specified differently from a beverage product — extraction yield and particle distribution usually matter more than aromatics. Describe the process and we will tell you what is workable.
