I also made a 50/50 grape & water slurry yesterday, was going through a jar a week. Funny story: I ran out of jelly last year and the wife was going to the Dollar store so I told her two grab 2 jars. She gets there and there's no grape jelly on the shelves, lots of strawberry etc. but no grape. She know the manager and asks why no grape jelly, he tells her "the crazy oriole feeders buy it all, I keep it in the back." She asks him for 2 jars and he gave her 2, she didn't tell him it was for the orioles.
