Comments

'Supreme' is the primary black colored fresh fruit cultivar in south Georgia. 'Supreme' has a very large berry size and good flavor. Among 'Supreme's' primary quality attributes are a crisp edible skin, and a firm pulp.

There are some negative issues with 'Supreme' including a somewhat low vine vigor which can lead to stressed vines when crop sizes are large. Some vineyards have had trouble with dead arms or vine death with 'Supreme', this problem is more pronounced the more north you go in the state.

'Supreme' is a proven leading cultivar in south Georgia, but may not be well adapted outside of this region.
