I know a bit about the Diacetyl issues in vaping but this article is interesting. I didn’t realize that it is found in nature and already in custard type of flavors. I’ve been buying flavor concentrates that don’t have Diacetyl ADDED which doesn’t mean there won’t be some naturally in the flavor concentrates.
Any way some people new to DIY might be interested.
