The term Sherris sack later gave way to sherry as the English term for fortified wine from Jerez. Since sherry is practically the only one of these wines still widely exported and consumed, "sack" is commonly but not quite correctly quoted as an old synonym for sherry. Most sack was probably sweet, and matured in wooden barrels for a limited time. In modern terms, typical sack may have resembled cheaper versions of medium Oloroso sherry. Today, sack is sometimes seen included in the name of some sherries, perhaps most commonly as the Williams & Humbert brand "Dry Sack".
Origin of the term
The Collins English Dictionary, the Chambers Dictionary, and the Oxford English Dictionary all derive the word "sack" from the French sec, "dry". However, the OED cannot explain the change in the vowel, and it has been suggested by others that the term is actually from the Spanish word sacar, meaning "to draw out", as in drawing out wine from a solera, which led to sacas. The word "sack" is not attested before 1530. Julian Jeffs writes "The word sack probably originated at the end of the fifteenth century, and is almost certainly derived from the Spanish verbsacar. In the minutes of the Jerez town council for 1435, exports of wine were referred to as sacas."
Historical background
The Duke of Medina Sidonia abolished taxes on export of wine from Sanlúcar de Barrameda in 1491, allowing both Spanish and foreign ships. English merchants were given preferential treatment in 1517, and distinction was upheld between second-rate wines, so-called "Bastards", and first-rate wines which were known as "Rumneys" and "Sacks". Málaga, formerly in the Kingdom of Granada, also took to using the name sack for its wines, which were previously sold as “Garnacha”. This wine was similar to another wine known as 'malmsey', made from Malvasia grapes.
