This thread has some info, seems most people don't consider it a suitable product to discuss on this forum. In my opinion its a fine enough drink when the weather is hot and your not looking to challenge your taste buds too much.
Waggastew .. Mate I am working of SWMBO says she likes it .. then well lets make it to appease her !! it is all good .. Beer and a happy wife make for a happy life ... ;-)
Had a six pack of Monteiths Summer Ale last week, but got the spiced one! (Is this the one you are talking about?)
Tasted a lot like ginger beer gone very wrong!
