Honestly, at $13/kg green from BeanGreen, you might want to ship it from him 😉 Or just fork out $20/kg - if you enjoy it, it's what 'entry level' top end greens are retailing for? Assuming you're doing 22gr baskets, it's still only $0.53/cup, or $0.17 for a single espresso (if you're using a single basket)
