Peak
early September through late September — full stalls,
full flavor. This is the stretch to plan around.
Late
Through mid-October — quantity for
preserving, and the stalls start dealing.
Season length
about 9 weeks end to end, shoulders included.
U-pick grapes in Pennsylvania
Bring clean snips and cut whole clusters into shallow trays — tugging shatters the bunch. The picking window tracks the band above: early
trips get clean fields, peak (early September through late September) is the sure bet,
late season is for quantity.
Farm-to-farm variation is real — up to two weeks either side of
the typical window. Plan the trip,
then call the farm before you drive.
Grapes
Look
Full, even color for the type with the powdery white bloom still on the berries and a green, flexible stem.
Feel
Berries should be plump and hold tight to the stem; shriveled stems or showers of loose berries mean old fruit.
Smell
Ripe bunches smell sweet and grapey at the stem end — Concords and muscadines perfume the whole stand.
Tip
Taste a berry from the tip of the cluster — it ripens last, so if the bottom berry is sweet the bunch is ready.
Keeps
Refrigerate unwashed in a vented bag; most grapes keep a week or two.
