Batch brewing is automatic drip coffee: a machine heats the water and showers it evenly over a bed of ground coffee in a filter, then gravity pulls the brew into the carafe below. It is the most hands-off way to make good filter coffee and the easiest to scale, from a single mug to a full pot for a crowd.

A quality batch brewer keeps water in the ideal 92–96°C range and wets the grounds evenly, so the variables left to you are grind size, dose, and the coffee-to-water ratio. A common starting point is around 60 g of coffee per litre of water, adjusted to taste. Pre-wetting the filter and giving the bed a gentle stir during the bloom both help even extraction.
