Overview¶

Production scheduling in a coffee roastery is the process of planning and sequencing roasting batches to meet customer demand, manage green coffee stock, maintain freshness, and make efficient use of roasting capacity. It sits at the intersection of inventory management, order fulfilment, and quality management, because roasted coffee has a limited shelf life and must be produced close to the point of dispatch. Effective production scheduling reduces waste, prevents stock-outs, and ensures customers receive coffee within the optimal freshness window.

Key Scheduling Considerations¶

Order lead time and freshness windows: Roasted coffee is typically at its best 3–14 days post-roast for espresso and 1–10 days for filter, depending on the origin, process, and packaging. Production scheduling must ensure that roasted coffee arrives at the customer within this window — meaning roasting must occur close enough to dispatch to be fresh, but far enough in advance to allow sufficient degassing. Most specialty roasteries operate on a 1–5 day lead time between roast date and dispatch.

Demand forecasting: Scheduling requires an accurate forecast of order volume by SKU (specific product/blend/origin) for the scheduling period (typically a week). This is derived from historical order data, seasonal patterns, and known upcoming orders (wholesale accounts, subscription runs).

Batch size and roaster capacity: The production schedule must fit within the roaster's batch capacity and session time: - Total session time = number of batches × average roast time + preheat + cooling + changeover time - Scheduling too many batches in a session degrades consecutive consistency; build in buffer - Order batch sequences to minimise flavour carry-over (e.g., roast lighter roasts before darker; washed before natural)

Green coffee stock availability: The schedule must confirm that sufficient green coffee stock is available for each planned batch. Scheduling is contingent on inventory — if a green coffee lot is running low, the schedule must account for transition to the next lot or a reduced production run.

Freshness rotation: Roasteries operating subscription or standing wholesale orders must produce fresh stock regularly rather than building large reserves. Overproduction of any SKU wastes both green coffee and packaging, and results in stale stock.

Sequencing Batches in a Session¶

The order of batches within a session affects quality and efficiency:

Lighter to darker: Roasting light profiles before dark profiles in the same session minimises smoke and aromatic contamination of the drum. Dark roasts leave heavier oil deposits and aromatic compounds in the drum that can affect subsequent lighter roasts.

Washed before natural/honey: Natural and honey processed coffees produce more chaff and residue in the drum; roasting these before washed coffees in the same session can introduce off-notes. Where possible, roast washed first.

Blend components together: When producing espresso blends from separate-roasted components, scheduling the component batches in the same session and blending post-roast ensures consistent freshness across the blend.
