What is a nitrogen flush?

EVCLO is nitrogen flushed to ensure the freshness of the oil while it travels before it is opened.  Nitrogen flushing simply means that nitrogen is vacuum pumped into the neck of the bottle after filling the bottle with oil. Flushing oil filled bottles with nitrogen protects against oxidative damage by removing the oxygen from the upper unfilled portion of the glass bottle and replacing it with inert, food grade nitrogen.  Remember that air consists of 78% nitrogen so it is very natural.  Many extra-virgin olive oils as well as naturally fermented raw wines and apple cider vinegars are nitrogen flushed to maintain freshness.
