@silverbullet07, I am a grower also so I try to use 100% juice and skip water. I could not do this in a food plant since it is too expensive, ,,,, water always costs out as 0 cents per pound product.
My read on a 4 to 5 pound web recipes is that they are fairly good commercial products. 3 pound recipes are the no name type commercial products.
The transition to high fruit means high solids (fruit acid) which can usually be balanced with finishing sugar, and in your berry ALWAYS can be balanced. the problems occure with extremely high acid as cranberry, rhubarb, lemon juice, currant . . . where it tastes fantastic in small dose, but you can't finish a glass in one sitting. Then the option of removing acid with calcium carbonate (powdered limestone) or potassium carbonate is your fix. ,,,,, or add a moderate acid fruit juice as pear instead of water ,,,, or add lots of water to make a sugar wine.
The science fix is to build a wine based on titratable acidity (TA)
