business news in context, analysis with attitude

The Los Angeles Times has a story about how climate change is affecting the US wine business.

"Climate change is not some abstract, distant worry," the Times writes.  "It’s creeping into their vineyards right now.

"And that’s a big deal. The United States is the world’s fourth-largest wine producer behind Italy, France and Spain, and California produces 80% of the nation’s vino. Retail sales top $40 billion, and the industry employs more than 30,000 Californians directly in growing grapes and producing wine and many more in related jobs. Here, as in other wine-growing regions of the world affected by climate change, there won’t necessarily be less production in coming years. But growers are switching varieties, tinkering with techniques and moving to higher elevations."

As far back as 2011, the story says, "a Stanford University study predicted that the amount of Northern California land suitable for growing premium grapes could shrink by half as early as 2040, due to increased heat.

"That’s bad news for the cabernet grape. Too much heat can mean the berry develops sugar before it has developed its full character, throwing off balance and coloring."
