Shoot and Inflorescence Development--Part 3

I started keeping a better photographic record of the Eichhorn-Lorenz Shoot and Inflorescence Development which is the first main stage taking the vine from bud break to stage 16. The first of these posts was on May 14, Modified Eicchorn-Lorenz: Shoot and Inflorescence Development when our varieties were between stage 4 and 9.
The next update a week later on Saturday, May 22, I posted Shoot and Inflorescence Development--Part 2, with photos taken on May 21, showed that the vines were between stages 9-15, with the Barbera leading the way.
To keep up with the consistency, yesterday, May 28, I took photos of the vines and this is what they look like now:
Variety Photo
Auxerrois
Chenin Blanc
Chardonnay
Cabernet Sauvignon
Cabernet Franc
Barbera
At this time, the Auxerrois, Chardonnay and Barbera are the leaders of the pack and the Chenin Blanc, Cabernet Sauvignon and Cabernet Franc are a bit behind. The contrast between the photos taken on May 21 and yesterday, May 28 shows that the vines are growing rapidly. We began disbudding on May 12 and finished on May 24. We are making another pass through the vineyard, our current canopy management is shoot thinning.
Last night, we had the first big rainfall since May 10th. The rain is much welcomed and should help with the shoot elongation stage that the vines are in now. But, that also means that we need to get moving on the shoot thinning!
