I live in the "old world" and my cellar goes through natural temp fluctuation from about 10°C to 18°C, with a few short term spikes from time to time. But to me that is normal.
Brave? Interesting perspective. From the current market driven world, where consistency is more important that uniqueness, I guess that is brave.
Today.
But there was a time each vintage was a vintage because it was unique. And it was special. That was kind of the implied point and definition of "vintage" after all, versus
a consistent wine from year to year. Making a vintage wine can be difficult. After all, one year may make a lousy wine, and sales can suffer. But not making a vintage wine means one may loose the delight when a wine will shine in a stellar year.
Oh, how the world has and is changing. Quarterly corporate results more important than long term quality.
Personally, I prefer each yearly wine as a vintage, even it fails, versus hedging one's bets and going for the consistent mediocre year and year out, year after year.
