Trust me on this one... if you want to make your first drink your last drink that you remember, get a 190 Octane with an extra shot of Everclear. 190 Octane gets its name from the 190 proof alcohol they use in it (meaning 95% alcohol by volume... to put it in perspective, Bacaradi 151 is only 151 proof or 75.5% alcohol). The extra shots aren't a full shot glass (they come in smaller vials), but for the price of only $1 each, why not splurge and get 2 (or 3)?
