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.

Not one member of my family, including me, like these extremely salty, much too strong a BQ taste to order more.  I purchased them on a recuring basis and i wish to cancel now.  I have received only one shipment. Cancel further shipments.  Not to our taste at all. These are Lowery pork rinds.

I have a Waring belgian waffle maker and was looking for a good batter to use. I tried this based on reviews and with add my strong recommendation for this mix.  It was very easy to make and the waffles had a wonderful flavor ... loved the malt flavor that came through.  I will definitely be buying more when the current mix runs out.
