Never pasteurized, classic honey is cold-extracted, filtered, and liquefied at low temperatures to preserve the aromas and properties of the honey while maintaining its liquid texture. Liquid honey conservation advice Raw honey lasts indefinitely! We recommend consuming it within two years of harvest. However, liquid honey will crystallize over time to return to its natural crystallized form. This crystallization of honey is normal and natural, occurring in all unpasteurized honeys. It can happen within 4 to 8 weeks, depending on the type of honey.
