No I am generally not a fan of instant coffee mixes. Sorry, I am coffee purist and Babylonian! But I see nothing wrong with giving these out. Many people will drink instant coffee mixes. You could make a real coffee mix and simply can it, now that would be interesting!
I am not a huge fan of the instant coffee mixes either. They do in a pinch, but would not be my 1st "go to" choice. I do think that would make a good gift for people who drink that sort of thing though. It's too bad I didn't see this earlier.
The only decent instant coffee mix that I ever had was this Asian brand. I believe it was called Vinacafe Instant Coffee. Someone gave me a packet of this stuff and if I had to drink instant, I wouldn't mind this one!
