Grapes varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common grapes varieties compare.

Variety	Best for
Red Seedless	Snacking and salads: sweet, crisp, and easy to eat whole.
Thompson (Green) Seedless	Fresh eating and roasting: mild and sweet, the green supermarket standard.
Black	Fresh eating and roasting: deeper, richer flavour with dark skin.
Concord	Juice, jelly, and jam: bold and jammy with seeds and a slip skin.

Which should I pick?

For snacking and fruit salads, Red Seedless and Thompson (Green) Seedless are the sweet, reliable supermarket defaults. No seedless? Black grapes are richer and work as well fresh or roasted. Reach for Concord when you want a bold, jammy grape for juice and jelly, though it carries seeds and a slip skin.
