Yep, we can grind your beans for you. We use an EK43 grinder, and the right grind size really depends on how you brew your coffee. Generally, a coarse grind works great for French Press, medium grind is ideal for something like a Hario V60, and fine grind is best for espresso. However, we recommend not buying pre-ground coffee for espresso since espresso machines vary a lot, and it's tough to nail the perfect grind without knowing your machine. Also, remember that pre-ground coffee loses its freshness faster. If possible, it's worth investing in a grinder to freshly grind your coffee each time.
