About us

Who we are

Hot Numbers is an Independent specialty coffee company established in 2011 with two successful coffee shops in Cambridge. Our Roastery was established in 2012 as the next step in our quest to produce the best coffee possible. 

Why Us?

We roast ethically sourced, speciality grade coffee (100% Coffea Arabica.) The aim with our roast process is to tease out all the flavour that the green bean has to offer, without masking any of those notes with bitter burnt or charred flavours you get from darker roasting.

We've removed the guesswork.

We use two state-of-the-art Giesen Coffee Roasters, each roast feeding into Cropster (data logging software). This means we can precisely control every one of the hundreds of variables which affect flavour and always have a record to replicate our results and produce consistently high quality coffee.

Ethically Sourced, Speciality Grade.

We source our coffee through suppliers who deal direct with coffee producers around the world. They select the highest quality Coffea Arabica each origin has to offer, with the most desirable flavour attributes and free of defects. This is what is generally meant by "speciality grade coffee." 

  • Speciality Grade fetches a higher price, reflective of it's higher quality (not determined by global commodity prices which are based on much lower quality and easier to grow coffee like Coffea Canephora,or disrupted by political and economic factors.)
  • Direct trade ensures the money goes into the producers pockets & that farmers are treated fairly.
  • Offering better prices for farmers creates a stronger impetus for improving quality further and helps to safeguard the future of coffee. (which currently is very uncertain.)
  • Better for the environment- higher prices reduce the need for intensive and pesticide reliant farming practices. (The majority of the coffee we roast is organic, even though farms are not always be able to pay for the certification.)
