I am going to make some Zin from frozen grapes and was wondering what should I adjust the specific gravity to I have gone on the internet and see that some Zins can go above 15%. Thank you in advance.

There's no telling where the SG will be with frozen grapes. There can be quite a bit of variation depending on where the grapes were grown and how ripe they were at harvest.
Many commercially produced California wines have 16 percent or higher alcohol. For most wines, this is a bit much. The alcohol can be a bit too "expressive" when the percentage is that high. To have 16 percent, they would have had to start at around 1.120. I strongly suggest starting out at or near a more reasonable 1.090.

You will have to bring the gravity up to 1.115 to get around 15%. You can adjust the gravity by adding sugar. Here is a link to WINECALC. Here you can use either the gravity or brix to find how much sugar you need.

I hope this helps it did help me.
