I think last year Voodoo had a January 2016 release of GNVP. Anyone know if it's a similar timeframe for 2017?
I could be wrong but I do not believe any barrel aged beers that Voodoo produces get released on a re-occuring schedule. The only exception to this would be caution contains real pumpkin which has been released twice now for pumpkin beer season.
I think if you post this in the Great Lakes forum you might get some better hits on this as Voodoo only does brewery only releases for GNVP. I know they released it twice this year (b1 and b2 of 2016) so it could be awhile but I also have 0 info on the topic. It had been a few years prior to this years releases ( I think around 2013).
They don't announce releases until the day of usually. Following them on social media is the best thing you can do for info on releases.
