My son had this Jablum roasted and ground coffee brought back from Jamaica and paid a lot for it.  I have drunk blue mountain for years when I can but this was shocking.  It tasted stale when you opened the bag and even worse when you drank it.  It was definitely off.  He bought 5 bags and every one we tried was the same.  I would never buy another.  We had bought another brand in a tin from Jamaica which was fine.  I think this is a con.  You get all the rubbish about it being tested in Jamaica, well I dont know who tests it but definitely not someone who likes good coffee.  I just dont understand how people say its any good. Maybe having paid so much for it its like the emperor's new clothes.

We received a box of these at work and the whole package was gone moments after opening it up!  Great biscuits and now I am ordering a couple boxes for a few gifts for people I can't figure out what to get...

I keep these on hand for car trips with the grandkids. You can turn a boring bottle of water into a flavorful Kool-Aid drink by just adding a single packet to it. Just open the bottle, pour in the contents of one packet, then close and shake. Each packet contains both the Kool-Aid mix and the amount of sugar that's needed for a single drink. Perfect size for a typical water bottle. We use reusable watter bottles with them, so we can fill them up with water when ever we need something to drink and then add the Kool-Aid.  They taste just like when you mix a regular full sized pitcher of Kool-Aid, just in a single serving size. These single servings work really well for us since we never drink a whole pitcher when me make one, and end up pouring half of it out. These were such a great idea!
