Have you tried black garlic?

If you have, maybe you get why I’d have a go at fermenting it into a drink. It’s got a deep, dark, smoky, molasses-like flavour.

This experiment is something @savage.craic enthused me into! It’s black garlic, unrefined sugar and a lot of ginger bug. I whizzed mine up with an immersion blender. Within 24 hours of leaving I could hear the tiny bubbles doing their thing.
