Adding creme de cassis to my mead

[pineapple]

I want to add Creme de Cassis to a small batch of my mead at the time I bottle it. My question is, will the increase in sugar cause the mead to carbonate or will the increase in alcohol have an adverse affect?. Any input would be most helpful, thanks

If you want to avoid any potential sugar content issues, many brew suppliers carry black currant extract flavouring. We've added this to our beer when we bottle with great results.

Thanks for the great information
