Note: the latest vintage (2018) released is cognac barrel aged: https://www.ratebeer.com/beer/struise-pannepot-grand-reserva-cognac/880159/, earlier versions were calvados. "Vintage 2005" description: Our PGR has aged for 24 months on oak barrels and has been bottled for the first time on the 27th of December 2007. The main difference with the Pannepot Reserva is that PGR matured the last ten months on Calvados oak barrels, adding extra complexity to the beer. We dedicate this beer as a tribute to Jeppe & Michael of Ølbutikken in Denmark. Those gentlemen were the first to discover our beers on an International basis back in 2004 and are responsable somehow for our beers being all over the globe since then. As a token of gratitude towards Jeppe & Michael, the first shipment of PGR was scheduled to Ølbutikken so they could be the first to launch its commercialisation.
