Purpose:
Using different leaf pulling protocols to get a petit manseng with a better balance of brix and pH with the overall goal of producing a dry PM.
Methods:
Three rows of a 0.6-acre block of Petit Manseng (101-14) with East/West exposure had leaf pulling on the north and south exposure on 6/30/2014. The remainder of the block had leaf pull on only the northern exposure, also on 6/30/2014. Differences produced from the two protocols were evaluated by maturity sampling (Figure 1).
Figure 1
Results:
No significant differences were found in any of the maturity control variables.
