There is 1 determinate grape that I know of - Sprite. I've only grown it a couple of times and can't tell you the taste as I don't care for red tomatoes.
As far as I can remember, that Aldi orange grape was NOT Zima. I don't know what company it came from. But from another store I got another orange grape called Sunbelle from a company called Sunset. I believe they are a Canadian Greenhouse grower. Similar but not exactly the same.

Someone gave me some Zima seeds and we grew them for the first time last year. But I never even saw them as we were busy and the tomatoes were really weedy last year.
