Honey drink

Clearing my Mum's cupboards, I came across this bottle of Glu-Mel. It's the bottle we brought back from a holiday in Portugal over 35 years ago.... My Dad was still alive. They obviously didn't like it very much, but I'm touched my my kept it , even though she had two house moves. It was one of those drinks that didn't travel.... Although this bottle certainly did. I'm not going to drink it however.
