Am I right about this?!

Am I right about this?

I have seen a question that has been answered incorrectly. The question asked was about vodka double wine. It does, or at least did, in fact, exist, but all it means is really strong vodka. My question is can anyone find any links or info to back this up. This is the info I found.



Vodka was generally referred to as wine and divided into types: normal vodka was called simple wine, the best of this type being called vino dobroye (good wine); still higher was vino boyarskoye (boyar's wine); finally, higher still was vino dvoynoe (double wine), which was extremely strong.
