'Carlos' was released by the W.B. Nesbitt, V.H. Underwood, and D.E. Carroll in 1970 from the North Carolina Agr. Expt. Station in Raleigh, N.C. 'Carlos' was selected in 1954 from the cross Howard x NC 11-173 (Topsail x Tarheel). 'Carlos' was released as a bronze juice and fresh market cultivar with a flavor similar to 'Scuppernong'.


'Carlos' is the predominant bronze colored juice grape grown today. Dry scars and even ripening facilitate the use of mechanical harvesting with 'Carlos'. In the past, 'Carlos' was considered a dual purpose wine/fresh fruit cultivar. However, the relatively small size of 'Carlos' makes it difficult to use as a fresh fruit cultivar in the current market. Our vines were healthy, and yields were good. The biggest problem we have had with 'Carlos' is berry rots, which have reduced juice quality in some years, and in others have nearly ruined the crop. 'Doreen' may be a suitable replacement the southern muscadine region, as it was selected for high fruit rot resistance. However, 'Doreen' is very late ripening and has more of a wet scar than 'Carlos'. 'Carlos' occasionally shows signs of Pierce's disease development.
