One last hurrah!

It is autumn isn't it?  This young Pinot grigio vine doesn't seem to think so.  Working in the vineyard this afternoon, removing clothes-pegs in preparation for removing the bird-netting, I looked up to see this shoot (which has 5-6 inch tendrils a little further down) reaching for the sun.  And sunny it is.  And warm.  It hasn't been below 66° F all week.  I'm loving it.
Now, young vines tend to remain a tad more enthusiastic later into the season than their more mature row-mates, but this is a little unusual for this far along in the year.  Grapevine shoots do not form a terminal bud like some plants, so technically they may continue to grow if there is sufficient heat (yup), available nutrients (apparently so) and adequate soil moisture (questionable).  However, with the onset of veraison a shoot's apical meristem dies back because now there in a new source-sink (point of usage) in town - the sugar hungry cluster.  I did cut the fruit off this vine quite early on in the season, so evidently it took it upon itself to redirect it's photosynthates.  Very enterprising of it, but it isn't half going to be surprised when we get our first frost.  Ouch!
