Kloeckera and Friends

Prologue: "In wild yeast fermentation, Kloeckera and Saccharomyces compete for nutrients, thereby generating unique, yeast-specific, secondary metabolic compounds including fatty acid esters that are important in the ultimate quality of the wine"...by Dr. Mark Herold, Joseph Phelps Winery Research Enologist. [Whew !]

The Rest of the Story: Rather than using a single yeast strain, more California winemakers are letting wild yeasts in on the act to add complexity. My tasters thought they could taste some of those "yeast-specific metabolic compounds" in the 1994 Napa Valley Joseph Phelps Cabernet Sauvignon...a brilliant sunburst of rich flavors. In fact, at our last tasting we selected the $20+ wine that delivered the most bang for the buck. For each wine, the total votes (the BANG) were divided by the retail price (the BUCK) and the Phelps Cab won.

Postscript: Although undetected at the time, Kloeckera and its buddies were fermenting grape juice 7,000 years ago. My palate is very pleased that they're making a comeback.
