He also called it 'juice/wine':

Mat 26:29 But I say unto you, I will not drink henceforth of this FRUIT OF THE VINE, until that day when I drink it new with you IN MY FATHER'S KINGDOM. http://www.blueletterbible.org/tsk_b/Mat/26/29.html Which He did!
Act 10:41 Not to all the people, but unto witnesses chosen before of God, [even] to us, who did eat and drink with him after he rose from the dead. http://www.blueletterbible.org/tsk_b/Act/10/41.html . Which means we have been living in the Kingdom of God/'millennium' [thank you whoever pointed out the misspelling of 'millennium'. I will never do THAT again!] lo, all these almost 2,000 years.
I'm not an expert on this, and although raised Lutheran, I alays had a problem with transubstantiation. It always seemed like cabbibalism to me. Furthermore, there were severe admonitions AGAINST drinking blood:
Lev 3:17 [It shall be] a perpetual statute for your generations throughout all your dwellings, that ye eat neither fat nor blood. *** http://www.blueletterbible.org/tsk_b/Lev/3/17.html
Lev 7:26 Moreover ye shall eat no manner of blood, [whether it be] of fowl or of beast, in any of your dwellings. *** http://www.blueletterbible.org/tsk_b/Lev/7/26.html
Lev 7:27 Whatsoever soul [it be] that eateth any manner of blood, even that soul shall be cut off from his people.
http://www.blueletterbible.org/kjv/Lev/Lev007.html#26
http://www.blueletterbible.org/tsk_b/Lev/7/27.html
There were LOTS of admonitions on that subject in Leviticus 17. http://www.blueletterbible.org/kjv/Lev/Lev017.html#10
Futhermore, God entered into the Holy of Holies ONCE AND FOR ALL for the removal of sin. I don't believe He meant to be a sacrifice over and over. After all, did He not say, 'It is FINISHED'?
1Cr 11:25 After the same manner also [he took] the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink [it], IN REMEMBRANCE [not SACRIFICE!] of me. http://www.blueletterbible.org/tsk_b/1Cr/11/25.html
Therefore, since God is the same yesterday, today, and forever, I'm inclined to believe the wine was SYMBOLIC of the blood. However, you might want to check out the commentaries [I like Matthew Henry and JFF&B], letter 'L', and see what they have to say. [I haven't done that.]
'TESTIMONY OF DONATION' - what does it mean? Anyone?
'cabbibalism' = cannibalism [did I get it right that time?]
