Я не люблю давать ссылки на википедию, как кладезь истинно верных знаний, но просто как одно из мнений:
Fino is the most delicate form of sherry and should be drunk within a year of bottling, although some argue that fino should not be older than six months. Once opened it will immediately begin to deteriorate and should be drunk in one sitting for the best results. If necessary it can be stored, corked and refrigerated, for up to one week after opening.
