Unreserved Wine Talk 370: Wes Pearson: What Happens When the World's Most Expensive Wines Are Tasted Blind
What really happens when the world's most expensive wines are tasted blind, without their labels or reputations? Why is the Len Evans Tutorial considered such a valuable experience in the wine world? How did Grenache go from a filler grape to one that producers take seriously?
In this episode of the Unreserved Wine Talk podcast, I'm chatting with Dr Wes Pearson, a senior research scientist at the Australian Wine Research Institute in Adelaide.

Key Takeaways
The current vintage of the Romanée-Conti Grand Cru, or that vineyard, is about $15,000 on release. They're not wines that are generally bought and drunk. They're bought as investments. And they're kind of these holy grail wines that you would never get a chance to see otherwise. And not only is it great to taste them, but you taste them blind.
The Len Evans Tutorial is a one-week immersive tasting session with the world's greatest wines. Not just Australian wines. You have a bracket of Pinot Noir, and within that, you've got DRC and you've also got all of the great Australian examples as well. It's meant to set your benchmarks for what is the world standard and what is the Australian standard.
Historically, Grenache was the filler in blends. Grenache loves the heat so you can leave it out in the vineyard. The Shiraz has to come in first. "We'll get the Grenache later when we have some space in the winery." It was used to fill up the blends. It had lots of flavor. It always had lots of alcohol as well. Then around 2010, a few producers started saying, we've got some pretty good resource here. Maybe we should think about investing a bit more time and effort into what we've got with Grenache.
