What it is

Roasting small batches of speciality green coffee on a compact roaster, then packing and posting fresh bags to customers across the UK. Many people start in a garage, outbuilding or small unit.

Your first three steps

  1. Take a roasting course or practise on a small sample roaster, and keep notes on each batch
  2. Source green beans from a UK importer and test three or four coffees with friends for feedback
  3. Set up a simple online shop with a subscription option and a brand name, then launch to friends, family and local social groups
Who pays

Home coffee drinkers, gift buyers and people who want a regular fresh delivery.

How it makes money

You buy green beans in bulk and sell roasted coffee by the bag, with subscriptions giving steadier repeat orders. Margin comes from the gap between green bean cost and the price per bag, after packaging and postage.
