I've both crushed and blended fruit & I can tell you that blending it (in a blender) makes for a LOT of sediment in your fermenter. I blended plums once & had over 6 inches of sediment in secondary. You'll lose a lot more of your wine by blending. Crushing allows you to place the fruit in a mesh sack & remove it easily, you hardly lose any of your wine this way. Another option you might consider is juicing the fruit. Thing about juicing is that there are very few recipes out there specifically for juice. You'd have to either adapt a recipe to use juice or develop your own. Makes it tough to use a commercially produced juice, as you have no idea how much fruit makes a quart of juice; and the juice yield varies from 1 type of fruit to another.
Crushing fruit is easy if you freeze it 1st. I used to pit & quarter fresh plums, but now I just freeze them after washing; once they thaw, you can simply squeeze them in your hand to both crush & remove the pit. Freezing also helps to break down cell walls & gives you a higher yield of juice, which translates into more fruit flavor in your wine. Also makes it easy to buy fruit fresh in season & save it for later. I highly recommend using a mesh sack to contain the fruit in the must, like I said, makes it really easy to remove the fruit & retain more wine; though some fruits will turn to mush & can slip through the mesh if you leave the fruit in too long.
Hope that helps. Regards, GF.
