Not sure if it’s been mentioned here, but Sigma Coffee is stocking many ‘highly rated’ roasters from around the world. Currently, they stock Manhattan, Dak, Onyx, Nomad, April, Native and Hydrangea and are looking to stock others soon such as Sey. I’ve tried Manhattan, Dak and April in the past and have been impressed by them all. Just to say this should lower the shipping cost if you’re wanting to try some of the world highest rated green coffee sourcers and roasters (of course this depends on what you like!). I’ve previously ordered a ZP6 grinder from Sigma with no issues at all. There’s also an area to suggest other roasters you’d like them to stock.
