BUNN - G1 HD Black 1 lb. Bulk Coffee Grinder

If you want to grind 2 pounds fast it’s the only way to go. You’ll overheat any of the prosumer grinders.

Bunn G1, it's a beast that will outlive us both lol I'm not a fan of the EK43. It's certainly better than the Bunn, but also considerably more expensive but I feel it's less versatile. It'll make you a better V60, but grind a whole lb through it and it gets hot. It gets the grounds hot. The G1 doesn't. In the coffee shop I often have people buying 1, 2, 3 even more bags of beans and they want them ground. I've done 12 1lb bags back to back on the Bunn. Totally fine. I do 1 bag through the EK and it gets hot. So yeah overall I think it's more versatile, indestructible, and good enough for anything other than espresso.

You might research commercial Bunn grinders, G1 or G3. They have a Turkish setting and burr grind/pulverize, but have no idea about microns. They are biggish and not very Kitchen stylish. You can always find some used on FBM or in Restaurant supply houses. It is a purchase for life.

I think this is very doable with some smart shopping. Not sure if it's available to your friend, but a used Bunn G series grinder would be the default option here in the states. Maybe a used HeyCafe 880? When going the used route, it's a great idea to check on replacement burr availability. Nothing worse than checking out a used grinder and smelling the fine aroma of hazelnut wafting from the grind chamber. Those oils can be a real bear to clean up and new burrs may be necessary. ETA: As mentioned, grinding a kilo of coffee for espresso is going to be taxing for most machines and will probably not be the best grind for the customers machine anyway. I would try to avoid it if at all possible.

Agreed. Get a Bunn grinder if your shop grinds beans for customers. Get an EK43 for grind on demand and pour overs
