If you are wanting to make wine out ofthen you need to know some facts before you get started. It is true that you can make wine from concentrate but it is important to understand the the acid content of wine concentrate is much higher than that of grapes that come from the vine. You will be making wine that has alcohol in it but it will taste more like than the wine that you are used to drinking.
So you may wonder if there is anything you can do to change this. Yes, you can neutralize the acid before you add the yeast to the mix because this will cut down on the acid content. There are many articles that are free online that will give you the recipe to take grape juice and turn it into wine but if you do not cut down on the acid it will keep that pucker grape juice taste so you need to make that adjustment. Before you ferment the wine you need to cut the acid content to about 50% so that means that you need to cut it with water.
Also you can use antacids to do this as well and using about 500 milligrams for 1.3 liters will do the trick. You just crush the tablets and let them dissolve in the juice and this will neutralize the acid for you.
Remember that making your own wine is not hard to do but you need to take the added step to neutralize the acid so that your homemade wine will not taste like grape juice.
