Chartreuse is the only naturally green liquor (from the chlorophyll of the herbs). And it's 110 proof. (There is also a milder, 80-proof yellow chartreuse made with honey.) It smells like Vitalis.
collinsmom said it tasted like cough syrup.Actually, it tastes quite a bit like Jaegermeister, though not as heavy. It has a spicier flavor, and with the extra proofage is decidedly more ethereal. All in all, rather tasty, though not for slurping: I had a mere finger's worth, and I wondered if I would be able to finish it.
collinsmom observed that if you took a sip and held it in the back of your throat for a moment before swallowing, it would clear your sinuses in no time.I quite liked it. (Interested sippers see me for a private tasting.)
