All sparkling wine is made by fermenting it twice, the second time in a pressurized environment.
Most Lambrusco is made using the Charmat or Martinotti method. A still wine is made. It’s then transferred to a pressurized tank where a second fermentation is provoked. The resulting CO2, a byproduct of fermentation, is captured and it’s what gives the wine its bubbles.
The classic method (also called the Champagne method in Champagne) calls for the second fermentation to be carried out in a sealed bottle. It has to be done by hand and it’s much more time-consuming and costly. And the resulting wines are among the most compelling in the world.
Taste our metodo classico Lambrusco tomorrow, Saturday, July 28, at Jaynes Gastropub in San Diego where our blog master Jeremy Parzen aka Do Bianchi will be leading a walk-around tasting.
