首先,“Sherry / Jerez / Xèréz”一詞有受到很明確的法定產區保護(PDO)。即使產自西班牙,也只有生產於「Jerez de la Frontera、El Puerto de Santa María、Sanlúcar de Barrameda這三個城市連線之間的區域(以下簡稱『雪莉三角』)」且符合特定製程規範的加烈葡萄酒,能在D.O. Jerez的定義下被稱為Sherry。(註:今年(2021)5月中旬有針對製造區域和熟成區域達成新的協議,所以預計產區範圍未來是有擴張的可能性的。)相較之下,”Sherry cask”一詞則沒有這麼明確而嚴謹的使用限制,並且也正是相關產業近年來持續試圖透過官方去加以規範的。
舉個例子。例如:Oban Distiller’s Edition,我們知道它是使用來自Montilla的Fino桶來過桶,而Montilla位在雪莉三角外將近200公里的另一個城市,換言之,其所生產的葡萄加烈酒是不能被稱之為Sherry的。然而,當我們實際在網路上進行搜尋時,就會發現有標註”Montilla Fino Cask Finish”的介紹,同時,卻也有標註”Montilla Fino ‘Sherry’ Cask Finish”的介紹。
