Happen to live in the town of Hammonton, NJ, blueberry capital of the world.Grew up pickin, and packing them most of my life (so far). Best tasting and largest variety is the Elizabeth, Blue Ray, and Blue Crop. Unfortunately the first two do not travel well. To get the best you need to get them right off the bush.
Used to pick Blue Ray’s in the soviet fiefdom of Red Hampshire (spit)...the berries were awesome1
And before the mockingbirds get them!
Decades ago my father grew bluberries in Winslow, Camden county, NJ.
