I have continued to be very bullish on Mourvedre for our colder continental climate here in Kansas City area. The Mourvedre is on 101-14 rootstock which I continue like versus 3309C. The reason is one, the vines are not as aggressive in growing wild and pushing excessive folage. It seems that 3309 rootstock is so vigorous that the vine continues to grow so excessively that you have to trim the vine every three weeks. According to the book released by Michigan State entitled, "Winter Injury to Grapevines and Methods of Protection", the lower vigor rootstocks such as 101-14 and Ripara Gloire are more desirable because they impart low to moderate vigor and this is often considered desirable to control vine size and to minimize the risk of winter injury to vines. Here is Mourvedre as of July 16th, 2008.

Most vinifera grapevines that I grow have a maximum two clusters per shoot. So from a fruiting bud, the shoot (it is later called a cane) that emerges will have fruit clusters. Normally, you will have two clusters that are on the fruiting canes and that is it! Since my Petit Verdot is on its third leaf, we have a full trellis of fruit. As I was observing the fruit a few weeks ago, I noticed that some of the fruiting canes had 3 clusters. I thought, wow, this must be an aberration! So I gave a call to my friend Ron Barrett from Kinkeadridge in Ohio. Ron used to manage the Erath vineyards in Oregon before moving to Ohio to challenge himself with growing vinifera in a colder climate. Ron grows vinifera and makes some damn good wine. Ron said it is common to have three clusters on Petit Verdot. Here is a picture that may show on close examination the reality of three clusters.
