I think its a matter of the beans quality
Hi Tim :-)
Sorry to hear you're not happy with the coffee. I did contact you directly to see if I could help you to get better results, but I've not heard from you, so please look for my email if you'd like some help.
I can assure you there's no problem with the quality of the beans, they're all SCA 84 and above, it'll just be a bit of work required with dialing in. Thanks.
