When I first tried this a couple years ago at my local, my first impression was that it tasted remarkably like Chartreuse... Finally bought a bottle today (12 Jul 2025) and tried it side by side with Chartreuse Verte. Though it's similar on the nose, the strength and peppery spice of the latter sets them far enough apart. I do agree that it'll sub in quite nice for Chartreuse Jaune. I'm not convince that it makes a mark in small doses in a drink. Do let it express itself.
