Ethanol and not the best flavor. This bottle has been open for months. Its 1/3 gone. I’ve hoped this bottle would open up. Nope. I know they are batch dependent. This one is a dud. Lots of enthanol, even after sitting in the glass a while. Flavor is meh. Im probably giving the rest away. Maybe a friend will like it. If they do, I have a back up. They can have it. Same batch too, 275402.09.
