Cyclical or structural? That was one of the most-asked questions in the wine business when everyone gathered for the Unified Wine & Grape Symposium in Sacramento last year.

Was the decline in sales due to a structural change? There were a lot of structural shift theories including generational change (bye-bye, boomers), heightened health awareness, affordability (a hot term right now), and more.

Other analysts, however, viewed the problem more in cyclical terms. The wine industry experiences periodic booms and busts. And consumers go through life-cycles, drinking less wine when young, more as they mature, and then less again when they start to “age out” of the market. Maybe we are just caught in the down-cycle and things will turn up if we give them time.

The Deion Sanders Theory: Both

A year later the answer looks clear to me. Structural or cyclical? The answer, which I am stealing from a 1995 Pizza Hut television commercial starring Deion Sanders and Dallas Cowboys owner Jerry Jones, is simple: Both. [Click on Deion’s image above to see the video.]

This looks to be the most serious global wine industry crisis in at least a generation, so maybe it is no surprise that it isn’t the result of a single force, but the “perfect storm” phenomenon. Certainly all of the structural shift concerns are at work and warrant attention and I’m not sure we have fully figured them out yet.

But this year attention has turned to the cycle problem in part because we can see it happening right in front of our eyes. But can we do anything about it? The problem is that the existence of large inventories has discouraged wineries from buying grapes and making wine. Vines are being grubbed up in California and around the world in response to the production decline.  Inventory cycles may even result in a shortage of wine grapes in a few years, which will be a strange sight after the recent surplus. A shortage? Read on.

Econ 101 and All That

The role of inventories in the phenomenon of business cycles was part of the syllabus when I first studied macroeconomics. The logic went like this:  Suppose there is an exogenous shock that reduced overall demand (see structural shift above). This leaves businesses holding unplanned excess inventories. They respond by reducing new orders (which deepens the decrease in demand) until stocks are depleted.

One characteristic of decentralized markets, and the factor that tends to make cycles repeat themselves, is the phenomenon of overshooting. When firms draw down inventories, they tend to wait too long to stop, creating a shortage. And when they build up inventories again they overshoot on the up side, too. This isn’t a strategy. It’s just what happens when you have to guess where the bottom and the top of the cycle are. And that’s a serious concern now, that today’s surplus could turn into a shortage in a few years.

Stocks and Flows

Right now we have large inventories in many parts of the wine market. Some wine producers have so much unsold inventory from previous vintages that they made very little (and sometimes none at all) in 2025. They won’t fully return to the grape markets until those surplus stocks either sell out or “age out.”

And, to be honest, some wine consumers have accumulated pretty big inventories, too, and don’t really need to buy a lot of wine in the short run. Wine production (which economists call a flow variable) won’t start to rise until inventories (a stock variable) have fallen for consumers, retailers, distributors, and producers. When that will happen is hard to predict, but it is the biggest question confronting the industry today.

The impact of high inventories and relatively low sales is a wine problem, but not just a wine problem. Jim Beam, the famous Bourbon producer, recently announced that it was pausing production for a year (a year!) to allow time for excess  inventories to decline to a sustainable level. And apparently there is a glut of Scotch whisky, too.

What Would Deion Do?

What will the market look like when stocks and flows are back in equilibrium? Not like it did before. That’s because of the structural shifts that have taken place. The U.S. wine market will be smaller and different, but it will still be there.

So what should we do? Focus on the structural elements as many did last year? Or try to guess how the cycle will play out and develop strategies accordingly? I don’t know what you are going to do, but I think I can guess how Deion would answer that question.

Both.
