Fruit "Wine" Maker
Yes, that's the way it's been done to reduce the cost of those products since 100% Blackberry, and many other berry juices would be prohibitive for most folks.
But, it's worth considering that what you are buying is a mix because so much flavor is lost in the fermentation that if you start with a juice that is only 10%-30% of 'that berry' then you aren't going to have anything in the end unless you add back some juice to back-sweeten, it's going to be a very light flavor.
I ordered a concentrate of Black Currant juice (UK product) that was very good but it too was a mix of Black Currant and other juices as well. I had considered it as a possible source for a Black Currant wine but in the end it is still cheaper to purchase can of Vintners Harvest Black Currant concentrate for my wine base. Unless I want to start another "Berry Patch" of Currants. (Wife might not tolerate that addition very well.)
