You will ruin good gin ( I will assume that all you have is good gin) and good raisins. I have tried it and it was too nasty. It might work, but, for me, it was not worth it. Cherry juice is much more palatable. I use tart cherry juice that is not from concentrate. I have used curcumin as well. Different stuff works for different people. Whatever you use, you have got to be patient, it takes a while.
