Once the natural progression of age alters Sherry's profile, new kinds of Sherry wines emerge. These wines no more fit neatly into one of the two broad groups. Various types of wine may be made by purposefully sweetening the drink. Wines made from sherry grapes fall into one of three categories: dry, naturally sweet, or sweet. Dry Sherry wines are those made entirely from grape juice that have undergone full fermentation, resulting in a low residual sugar level. Sherry wines that are naturally sweet are created by halting the fermentation process, which preserves the majority of the grape's natural sugar rather than processing it into alcohol. Sweet wines are created by mixing the aforementioned varieties. Theoretically, the possible alternatives are infinite.
