Judean date palm human-assisted germination of a seed (the claim in 2012 of a 32,000-year-old arctic flower involved fruit tissue rather than a seed). The palm, named Methuselah (not to be confused with a bristlecone pine tree of the same name), was about tall in June 2008. , it is reported at high, having been transplanted from pot to earth. By May 2015, the palm was tall and was producing pollen. Even if the pollination of a female Judean date palm, grown of a seed from the same batch, with Methuselah's pollen should succeed, the resulting fruit would not represent the recreation of
Palm wine the sap to prevent it from fermenting. "Neera", similar to fruit-juice products. is relatively rich in potassium. In India, palm wine or toddy is served as either "neera" or "pathaneer" (a sweet, non-alcoholic beverage derived from fresh sap) or "kallu" (a sour beverage made from fermented sap, but not as strong as wine). Palm sap contains natural yeasts, which perform the fermentation of glucose to alcohol, as well as acetobacter, which subsequently converts the alcohol to acetic acid (vinegar). Optimal consumption time is one day after tapping, when the vinegar content is minimal; beyond this time, it becomes increasingly sour.
