Zignum Platinum is the un-aged expression bottled straight from the distillery without aging. It is considered to be the purest expression of the agave.
The Beverage Testing Institute said in 2010 that Zignum blanco was "a very clean, stylish and mixable mezcal that successfully eschews traditional smokiness for approachability." They reiterated in 2011 by calling it "Very polished and modern styled, along the lines of an artisan white rum."
Zignum mezcals are part of the new distillery designed for mezcal production in Oaxaca. (Mezcal and the more well-known tequila are both agave based Mexican spirits. Mezcals are produced outside of Jalisco and can be made with varieties of agave other than the Blue Weber, which is required for tequila.) The Casa Armando Guillermo Prieto Distillery was founded in 2008 and is part of an investment by Coca Cola of over $48 million, according to the write-up at Narco News. It is described as a modern facility, leveraging technology for highly efficient and clean manufacturing processes as opposed to the more traditional, peasant-driven, artisanal production of many mezcals.
