Ditto to the James's Gourmet and Karimikui - a beautiful coffee, from one of the very best roasters.
It's a lovely idea to try coffee from all the world's great roasters. But, I've heard that flying coffee once it's roasted can do strange things to it (air pressure in cargo holds and all that jazz), and, together with what I imagine must be significant shipping costs, freshness, and transit miles issues, it might be best to try these roasters if ever you happen to be in their home countries... And in the meantime, simply take advantage of so many different, wonderful coffees that have been skillfully roasted more locally in the UK, by those various people mentioned above...
