I drank some grape sap

[Mr Skeptic]

Earlier today, my grandma asked me to cut down a grape vine. When I did, I noticed a largeish quantity of sap flowing out. I tasted a drop, and it tasted like water but with a very subtle flavor. Intrigued, I put a glass under it and gathered about a glassful, and drank it. It seemed more refreshing than plain water, with a subtle but interesting taste.

 

So now I'm curious about the composition of grape sap. I'm fairly sure its not poisonous as both grapes and grape leaves are edible, plus I'm not dead. But what sort of things does it have? As for season, the vine did not yet grow its leaves but I suppose would have fairly soon.

It's pretty much just water and sugar, with some associated minerals, nutrients, hormones, etc.

I already drank grapevine sap when I accidentally pruned the vines a bit too late...it must be full of benificial properties! Curiously enough, my grape vines produced more that year...

Wood typically contains potassium and magnesium. Sugars are likely xylose perhaps some acids or something. If you gather a glassful it was probably mostly water.
