Tried my mustang grape wine while racking and seems real thin. Any ideas . What can I do to give this more body. Didn't really have enough grapes I think
I doubt that you took a SG when you started, so we don't know where the wine is at right now. You didn't mention adding sugar, so the ABV is likely low...mustang grapes are not very sweet to start with...so, I'm betting you have five gallons of very thin tart grape juice.
You got two choices now. 1. Leave it alone, easy, you're almost done...just let it sit six months and bottle....it will be what it is, a thin wine.
2. You can tweak the heck out of it! You can buy a can of concentrate wine making juice. You can chop up and throw in a box of rasins or currants. Add sugar...we have no idea how much, but if you did not add any to start with, you could a couple of pounds now...make a simple syrup 2 part sugar, one part water and boil until clear, cool, and add it. You can dump in cans of frozen juices grape, apple, whatever as long as it is preservative free...you could add a couple of cans per gallon....where did I get that number? I just figure it'll work...we don't know where we started, we don't know where at now, so it's either a crap shoot or a work of art in progress! Short story...add more stuff to restart the fermentation and keep on trucking.
I WOULD TWEAK IT! It may never be a great wine. But, it can be a wine you learn a lot from. Good luck!
