My old job consisted of non-stop batching of fresh margaritas for festivals & distributor meetings; where fast, consistent spicy margs were in high demand. I was introduced to a BEER growler keg that used a tedious C02 tap adapter to force out the NON-carbonated cocktail.  It was great; until it wasn't. I noticed an obvious need for a new type of cocktail container that didn’t rely on CO2. Everyone used glass jars & threw away their leftovers. I needed something better; something different but I didn't have the need for complicated setups nor C02 cartridges that weren’t reusable. 

And just like that, the Pump Keg was born...
