Start with your brewing method and the flavours you enjoy. Espresso and filter labels are useful recommendations for how a coffee has been roasted and intended to brew. They do not mean the beans come from two different kinds of coffee plant.
If you mostly drink espresso or cappuccino
For your first bag, choose a coffee recommended for espresso. If you enjoy milk drinks, chocolate and nut tasting notes can be a helpful starting point. For black espresso, decide whether you prefer a rounded cup or a brighter, fruitier one. Neither preference requires choosing the darkest roast available.
Use a recipe to keep your adjustments consistent. For a conventional double espresso, 18 g of ground coffee and 36 g of beverage is one possible starting point, if your basket suits that dose. Treat it as a starting recipe, then adjust for the coffee and your machine.

If you use a V60 or filter machine
A filter recommendation is a practical place to begin. Read the tasting notes and choose something that sounds appealing rather than chasing a particular origin. For a V60, try 15 g of coffee with 250 g of brewing water as an initial recipe, then adjust the grind and taste again.
An espresso grind is usually much finer than a filter grind. If you buy ground coffee, name the actual brewer so the grind can be matched to it.

Make your next bag an easier choice
Keep a brief note of the coffee, recipe and what you liked. Change one brewing variable at a time when experimenting. Tell the KOPI team what you brew with and what worked in your last bag; that is useful information for choosing the next one.
