Is Mad Dog 20/20 Red Grape Wine Gluten-Free?

It is correct to use gluten-free as an adjective, like gluten-free wine. If you say, "Is the wine gluten free?", there is no hyphen. This is why college is important, morons.

It is gluten free.

Can you help? Is mad dog 20/20 red grape wine gluten-free?
