Frozen Juice Concentrate to flavor alcohol base before bottling?

I was wondering if juice concentrate would go bad if I used it to flavor an alcohol base and then bottled it? The only ingredients other than water and juice in the can are citric and ascorbic acid...preservatives. This will pretty much be mixed with water, ethanol, and sugar and then be bottled in gl to sit for a few months. But will the juice go bad at a temp. of about 60-70 degrees if it is bottled and sealed?
