Concord grapes when to pick?

Here are some signs to look for to determine if your Concord grapes are ripe:

* Color: The grapes should have a deep, almost black color.

* Texture: The berries should be firm and plump, not soft or mushy.

* Taste: The grapes should have a sweet and slightly tart flavor.

* Sugar content: You can use a refractometer to measure the sugar content of the grapes. Ripe Concord grapes usually have a Brix level of 18-22.

Important factors to consider:

* Climate: Warmer climates will ripen grapes faster.

* Variety: Different Concord grape varieties may ripen at slightly different times.

* Growing conditions: Proper sunlight, water, and fertilization can affect the ripening process.

Tips for picking Concord grapes:

* Pick on a dry day. This will help prevent mold and mildew.

* Use pruning shears or a grape-picking tool. This will make the job easier and prevent damage to the vines.

* Pick only the ripe grapes. Leave any green or unripe grapes on the vine.

* Store the grapes in a cool, dry place. They can be kept for several days if stored properly.

If you're unsure when to pick your grapes, it's best to contact your local agricultural extension office for advice. They can provide information specific to your region and grape variety.
