What are you drinking right now?

Guys, I'm in a pickle. My recently beloved "Moroshi" wasn't available at the nearest store where I usually buy it, and at another store, it was suspiciously cheap, so I had to choose from a variety of unfamiliar vodkas. I chose "Drova," and I wasn't really disappointed.
The taste is quite mild, with a bitter but original and pleasant aftertaste (oak?), the smell is weak and not at all harsh. The only problem is that a few seconds after a sip, it gives you a slight headache.
I recommend drinking it with a delay, not immediately after a sip, but after a couple of seconds. This way, you'll feel the original taste and avoid the aforementioned headache.
Overall – 7/10 for 300 rubles.
The vodka comes in three versions – with oak, walnut, and birch charcoal. The oak version also includes oak bark, the birch version includes birch sap, and the walnut version also has something else. I took the oak version; next time, I'll try the birch one.
