Hmmm...well, I would think that they're underripe. Have you tasted them? What did they look like on the outside? They should be dark red, heavy for their size, and smooth (not withered). They will not ripen after picking.
The ones I've bought so far have been beautiful, but a little musky/earthy. I can't remember if that's normal or not. But the juice has been good, and hopefully they'll make good pomegranate schnapps.
On a related note, have you tried PomWonderful juice yet? O.M.G.!!!! It's soooooo good, especially the plain and the pom-cherry. Expensive, tho.
