Vile Vintage

You touch a bottle of wine and imbue its contents with dark magic, turning it into a powerful ingested poison without altering its appearance or scent. Any creature that drinks the wine must make a Constitution saving throw or take 6d6 poison damage and be poisoned for 24 hours. On a successful save, a creature takes half damage and is not poisoned.

If a successful dispel magic is cast on the bottle, its contents turns back into normal wine. Alternatively, destroying the bottle has the same effect, even if the bottle was emptied beforehand.
