That settles it. What she has is chokeberries, which is good. Because I bought 3 chokeberry bushes in March, 2014. I'm mildly surprised, but there have been no berries yet, three years down the road.
I bottled my chokeberry wine a week or so ago and it was good. Very good. I bottled a little over half of it dry (specific gravity about 1.000) and the rest semi-sweet. Upon one of the early rackings, I topped it with a quart of Tart Cherry juice and that is the dominant flavor.
The recipe I used was 40 pounds of frozen aronia berries in a paint strainer bag. I mashed them by hand in the bag in the bucket. I added a couple of gallons of water to get enough liquid to cover the bag. Some of the water contained 8 pounds of dissolved sugar and was boiled to dissolve the sugar. Then I added more sugar to bring the specific gravity up to 1.100. Everything else was typical. A quarter teaspoon of k-meta and pectic enzyme, 12 hours later 4 teaspoons of yeast nutrient and 1.5 teaspoons of energizer, the sugar, and a packet of Lalvin 71B-1122 yeast. I kept the berries in the mesh bag during fermentation except when I poured the boiling hot sugar water in, I poured it into the bag and then knotted the bag and let it float in the must (punching it down and flipping it over a couple of times a day.) When primary was pretty much done, I squeezed and wrung the bag by hand, then transferred to a carboy. Then, several days later, I racked it into another carboy and topped it up with Just Tart Cherry juice. It has made as good a wine as I've ever made, but I would not do the cherry juice again. Unless aronia tastes just like tart cherry juice, the addition of the juice overpowered the aronia flavor. I didn't expect that with one quart in 6 gallons. I racked it about every 3 months or so, adding .25 tsp of k-meta at each racking, then stabilizing with potassium sorbate before bottling. When I tasted it before bottling, I thought it tasted a little sweet for a dry wine at 1.000. But 1.000 is a high specific gravity for a dry wine.
