Technological potential
Exalta B clusters are moderate to large size. The berries are small to moderate size with a fairly thin skin and juicy pulp with a slightly muscat flavor and a very pleasant floral character. The clusters must be well exposed in order to obtain good coloration; non lignified grape seed tissues are present but not very noticeable. This variety is not very sensitive to shattering and is suited for conservation and travels well.
