Based on these verses in Leviticus 19:
23 And when ye shall come into the land, and shall have planted all manner of trees for food, then ye shall count the fruit thereof as forbidden; three years shall it be as forbidden unto you; it shall not be eaten. 24 And in the fourth year all the fruit thereof shall be holy, for giving praise unto the LORD. 25 But in the fifth year may ye eat of the fruit thereof, that it may yield unto you more richly the increase thereof: I am the LORD your God.
a ceremony in which the vineyard has its sanctity transferred in the fourth year so the crops can be used is performed.
And as the poster informs us, this Wednesday at 4 PM, you're invited to the vineyards of Shiloh to participate in the ceremony sponsored by Meshek Achiyah which produces olive oil and as well owns vineyards.
