Full disclosure...we borrowed this trivia from an online source ( and we have some experts that beg to differ with the results. One of our vineyard crew members informed us earlier that there is a single california company that produces 62 million gallons, as gave us the correct number for California production. He also mentioned that 800 vines per acre must be an older number because vines were more spread out then and today they are a lot closer together because there is farming equipment build small enough to go between thinner rows.

In addition, one of our WillaKenzie Estate friends wrote us to shed some light on the following...

"When was the corkscrew designed?

I believe the answer of mid 1800's is incorrect.  The first American patent was  mid 1800's but there were functioning corkscrew designs many years earlier.   

The English were the first to seal wine bottles, using cork imported from Spain or Portugal.  Obviously, corkscrews were invented as an easy way of removing the cork from a bottle. In England corkscrew Patent No 2061 was granted to Samuel Henshall, Princes Street, Parish of Christchurch, Middlesex, on August 24, 1795.

Corkscrew historian Ron McLean from the "The Virtual Corkscrew Museum" says:

"It is unknown when and who made the first corkscrew. The first corkscrews were derived from a gun worme, a tool with a single or double spiral end fitting used to clean musket barrels or to extract an unspent charge from the barrel. By the early 17th century corkscrews for removing corks were made by blacksmiths as using a cork to stopper a bottle was well established."
