Answer:
Good Question. No. he holy grail was the grail Jesus drank out of during the last supper. He told his apostles, "Drink this; For it is my blood." But it wasn't really blood, it was actually just red wine. So no.
****************
Christ also added the words"Do this in remembrance of my blood which was shed for you". What He was telling the brethren was that the future church was to remember him by the symbolic drinking of His blood at a Sacrament to be held each Sabbath day. In todays chuches water or unfermented wine is used.
