It depends which high mountain coffee you're looking for...Colombian, Jamaican, Ethiopian??? I've used Hill & Valley for years now, they sell single estate coffees as well as their own blends, all of which are very good. http://www.hillandvalleycoffee.co.uk/
Thank you all for your help. You are better than an internet search. My local tea and coffee supply shop closed down without us knowing and having found a lovely coffee wanted to continue our supply which now we can. Thank you again
