This is an investment in pleasure, it’s something one shares, wine is all about sharing. – Steven Spurrier
One of my French friends taught me that time is relative. The 1345 completion of the Notre Dame Cathedral in Paris was something she considered recent history, while knowing that our country was discovered in 1521 makes me think otherwise.
That said, having a momentous event in wine history happen 50 years ago may seem like it only happened yesterday, but a lot has transpired in California winemaking since then (including the 10th anniversary of my published article on the topic).
