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.

VarietyBest for
Red SeedlessSnacking and salads: sweet, crisp, and easy to eat whole.
Thompson (Green) SeedlessFresh eating and roasting: mild and sweet, the green supermarket standard.
BlackFresh eating and roasting: deeper, richer flavour with dark skin.
ConcordJuice, 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.

Frequently Asked Questions

How many cups is one medium grape?
One medium grape (about 5 g) gives roughly 0.03 cups of chopped flesh. A small one (around 3 g) yields about 0.02 cups and a large one (around 8 g) about 0.05 cups, so set the size selector to match the grapes you actually have before you trust the figure. Open grapes converter
How much does a medium grape weigh?
A medium grape weighs about 5 g, with a small one around 3 g and a large one near 8 g. That range changes the weight of any recipe that counts grapes by the piece, so set the size selector to match what you actually have before trusting a cup or gram figure.
How much does an average grape weigh?
An average grape is the same as a medium one: about 5 g. A small grape is lighter at around 3 g and a large one heavier at about 8 g, so the size you actually have changes the total for any recipe that counts grapes by the piece rather than by weight.
Which grapes variety should I use?
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.
How much does a large grape weigh?
A large grape weighs about 8 g, noticeably more than a medium, or average, one at 5 g or a small one at 3 g. Set the size selector to large to convert cups, grams and ounces for the bigger grapes you actually have on the counter.
