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.

This orange soda is clearly more healthful, and it tastes tangier, although somewhat less sweet, than other orange sodas.  The one big drawback for me was that this drink lacks caffeine.

Drank an instant green tea from a major producer for several years. Then they changed production and began using sucralose which I don't tolerate well. Tried several different teas before I found Stash's instant green tea. I like it best with a little fresh lemon lime juice. I can drink all I want--don't even need sweetener. Plus as I understand it, it's just made from dried, pulverized green tea leaves--no chemical process. Also it's very coolby I get a discount forn having it delivered by monthly subscription. Phil K.
