I quit drinking in my 30s, it was interfering with my Ketracel White addiction and had to go.
It’s just really sweet. Too sweet for me. The root flavor is hard to describe really, I can understand the toothpaste comparison, but I wouldn’t say it tastes like toothpaste.
I come from a country that uses artificial mint taste for toothpaste. That’s what I have associated with toothpaste. But I know other countries have other flavors too (like spearmint and such), which taste very different. We also have Malta which is extremely sweet non alcoholic malt beverage. The taste is not strong but I associate it with overly sweet drinks.
