The Library offers such a wide choice of roasters

Sigma are doing a great job making available beans by Arkansas roaster Onyx. This is particularly good if you brew espresso or pour over in such a way that it is important for you to know how the bean is roasted. Most roasters provide no information about this, whereas Onyx are completely transparent about thier roasting process which makes my espressos so much easier to dial in. Sigma's roaster service The Library is such a great concept offering beans to rest or rested beans to use straight away.

Simply the best specialist coffee bean…

Simply the best specialist coffee bean shop in the UK, perhaps Europe - who knows - maybe the galaxy!
The range carried is incredible, and ever changing. He stocks genuinely fresh, small batch coffees from roasters from many locations in the UK and well beyond, only carrying what is good and fresh. You can buy by age as well, so you can buy ready-to-brew, or build up your stocks for the next couple of months.
Not just coffee, though, I've bought a fair bit of equipment, including a manual, and later electric grinder, and several bits of brewing tackle. It's all the top quality gear that he carries. He's clearly a proper coffee enthusiast.
Customer service, should you ever need it, is outstanding. He really bent over backwards to help me out after an order I placed for some expensive kit got despatched to the address I'd moved from a year earlier. I called this my fault, as the Shopify thing autocompleted my old address and I didn't notice. But he took on helping me out, and really went further than I could have expected.
I still have a subscription at one other online seller, but 90% of my coffee now comes from here.

Wonderful service

I recently purchased a set of SSP High Uniformity (Red Speed) burrs from Sigma Coffee UK, and I couldn't be happier with both the product and the customer service. David was incredibly helpful and prompt throughout the process, especially when I needed to arrange a return and swap for the burrs I truly wanted. Communication was quick, clear, and friendly at every step.

I highly recommend Sigma Coffee UK for their outstanding customer service, wide selection, and genuine care for their customers. Thank you, David!

Great company, great customer service.

Great company, good customer service. There was an issue with my order (around the colour of some Timemore nano coffee scales I ordered) but they sorted it out immediately. Very happy with my experience.

Genuine D64 Grinder

Signed up to their mailing list and got a 10% off offer after a few days. Ordered a DF64 grinder Friday afternoon and it was with me by Saturday lunchtime. Replied to my query overnight, excellent customer service. The grinder came in a D64Coffee box (common chinese source I'd guess) and is a quality bit of kit. Would happily do business with sigmacoffee again.

Meraki Espresso Machine

I am very happy to share my experience with you about my purchase.

I was looking for a coffee maker (Meraki) and ended up finding Sigma, and what a pleasant surprise! David was quick and helpful from the very beginning in answering all my questions and providing support for everything I needed. He understood what I needed and did everything possible to ensure everything was resolved in the best possible way.

I am sending this message from the bottom of my heart, because I received incredible support from them.

Once again, thank you David and the entire Sigma team. You have gained a customer for life!

Fast delivery and good range of coffee…

Fast delivery and good range of coffee gear. Great to see Weber Workshops products offered but would like to see the whole range including EG 1. Love the coffee library - had some amazing coffees from a whole host of roasters. Had a few orders from Sigma and its all been flawless, first-class service and very good gear and beans. My go to!

Above and Beyond Service

David, the company owner, went above and beyond to sort out my order, which I had messed up due to no fault of Sigma. David sorted out my return and sent a replacement quickly with no extra charge. I will definitely be using Sigma again and again.
