And so it perspired water faster than acid, concentrating sugars at low brix. I've never seen anything like this in my life. And I remember tasting and thinking to myself, we have to capture this now! The pH was perfect. Everything was perfect. A lot of people were talking about irrigating to plump up the grapes, but we’re a whole-cluster house and try to use whole bunches whenever we can instead of destemming. We don't irrigate because it yields resinous, sappy stems. And so we picked then and it was the single best decision that we made. I love that vintage so much. We had a similar situation with 2022 and made a call. 2022 is buoyant, fresh and light but also denser than 2017. You get this concentration, but at low ethanol levels.
Can you talk about why you decided to go 100 percent, or nearly 100 percent, whole cluster in your fermentation?
For me it's the aromatics. I think what attracts me the most in wine is the aromatics – when you smell a wine with complexity, nuance and depth. If a wine is mute aromatically but texturally complex and amazing, I'm not as enamored by it. It goes back to a visit I did in Burgundy and Bordeaux with my grandfather [Robert Mondavi]. He wanted to show us what he saw in ‘62 that gave him this fire in his belly. On that trip, we visited Anne-Claude LeFlaive [of Burgundy’s Chardonnay producer Domaine Leflaive], who is one of my heroes. I always say the women of Burgundy changed the way that the world farms, because it was Anne-Claude really pushing biodynamics before anybody. I just fell in love with her vision and farming. And our second stop was with Aubert de Villaine [of Domaine Romanee-Conti] who is another one of my heroes in wine, and we visited the vineyards. Absolutely beautiful. Remarkable. Then we dropped down into the cellar and the wines were explosively aromatic. I couldn't get over the aromatics – the rose petal, the tea, the lift – and the thing they were doing different was whole cluster. So when Dante and I began RAEN, I thought, can we can make a liquid that has this lift and this buoyancy and this freshness?
This is why we've selected hillside sites – well-drained sites. Because I don't think whole cluster does well in all vineyards. And it doesn't do well in all circumstances, all vintages. Whole clusters also allow you to to pick earlier, with 12.5 percent to 13 percent potential alcohol, but there’s usually so much total acidity that if you destemmed it, it would be angular and abrasive. Because of the clusters, there's a little potassium in the stems that binds to the tartaric acid, forming potassium bitartrate, raising the pH slightly and giving this incredible texture. You get all of these dimensions: aromatic lift, freshness and brightness and then texture and richness on the palate, which I love.
