I have a Specs close by I'll check it when I get the chance.
Couldn't open the link to pisco porton or find what TJ offers, but accorsing to Ken it is "Pisco of the Gods" which is unknown to me.
I plan on providing a couple bottles from my own. How much more dare we talking about. I have no clue how many people are coming and planning on drinking. Pisco Sour requires more volume than drinking it on its own, I guess 8-12 glasses of pisco sour per bottle (I make it strong, but we can titrate). Of course we can also serve smaller shares, since it can be treacheous.
