| Alden |
| reddish-blue variety with very large clusters and large berries. Berries have firm texture and an adherent skin with a mild labrusca and muscat flavor. |
| Almeria |
| green-skinned, small-seeded, medium-large fruit with firm, juicy flesh, and tangy sweetness. Ripens late midseason, fall through mid-winter. |
| Aurore |
| (Seibel 5279) The most widely planted non-labrusca grape in New York. Processors have used Aurore to extend the harvest season since the fruit matures in late August and early September, before most other varieties are ripe. The vine is productive and vigorous, and produces large bunches of amber colored berries. Bird damage and fruit rot are often a problem. Wine quality is poor and it is being replaced by interspecific varieties of higher quality. The major use has been for bulk wine production, frequently blended with V. labrusca varieties. |
| Autumn Royal |
| blue-skinned, seedless, medium to large oval fruit with a crisp, sweet-tasting flesh. Ripens late mid-season, fall through early winter. |
