Wine Grapes vs Table Grapes

Table Grapes Are Fat and Sassy Table grapes are grown in a way to make them more physically appealing. They are larger, seedless, with thicker pulp and thinner skins to give them that ideal ‘pop’ when you eat them. Table grapes have less acidity and also less sugar than a wine grape.

Wine Grapes Are Lean and Mean Wine grapes are grown to produce the sweetest and most potent grapes. They are smaller, riddled with seeds, have thicker skins and higher juice content (vs. pulp). Wine grapes are delicate and difficult to transport. When you eat a fresh wine grape they ooze apart leaving you with crunchy bitter seeds and chewy grape skin.

Wine grape vineyards commonly use vertical trellises to manage the greenery (aka canopy) and grape exposure to sun. The goal with wine grapes is to concentrate the flavor of the grapes produced.

Table grapes are grown in a way to reduce clusters from rubbing other clusters, stems or leaves. A trellis system that lets the grapes hang independently is better for producing picture table grapes. Table grapes tend to be more vigorous than wine grapes and grow in areas with soils high in nutrients such as river valleys.
