Shared Notes Wines, plus Coffee too

Bibiana Ravé

Bibiana Ravé, winemaker and co-owner of Shared Notes, joins Dan Berger and Daedalus Howell on California Wine Country.

Bibana has been on CWC twice, first on this episode of August 29, 2019, to talk about her own wine brand Alma de Cattleya. Then, on April 5, 2023, Bibiana and her husband Jeff Pisoni were on this episode, to talk about Shared Notes.

Bibiana grew up in Medellin, Colombia and studied enology in France. They are tasting a wine from Shared Notes, a winemaking project that she shares with her husband Jeff Pisoni. It is a blend of Sauvignon Blanc and Semillon. The blend is a bit different from year to year, depending on how the Semillon tastes.

French Winemaking in California

Bibiana practices French winemaking techniques in California. She describes winemaking as a personal experience. During her time in France, she stayed there and focussed on French wines only. She didn’t even study Italian or Spanish wines.

CWC is brought to you by Deodora Estate Vineyards. Visit Deodora to discover 72 acres in the Petaluma Gap that are producing exceptional Chardonnay, Pinot Noir and Riesling.

Her wines are “bone dry” with no residual sugar. They are on the low-to-middle alcohol level. She believes that it is truly all in the vineyard. They work with great vineyard sites. Their Sauvignon Blanc comes from the Ridge Vineyard, which Dan says is one of the best. The vines are 60 years old and have a low yield per acre. She ways that she could not make the wine that she does, if the growers were not as committed as she is. Dan Berger says this wine shows the ancient style with all the dry flavors that it requires. “Very few people in this world make wine that you want to open when your child is 21.” These wines will support 20 years in the bottle.

[12:38] Dan Berger: “Most people don’t realize, in the olden days, they would make a wine that was one of the greatest wines in the history of mankind and the next vintage they would make something that was undrinkable. Because they didn’t have the science behind them to tell them what they needed to do! Now we have science, so we can do what we need to do to make great wine every single year.”

Every choice is a force on the vector

There is a limit to letting the land and the vineyard speak for themselves. There are choices such as what to plant and where, how many vines per acre? For example, the difference between 848 vines per acre and 2420 vines per acre can completely determine the concentration, the phenolic ripeness and the quality of the fruit. Bibiana describes how she and Jeff wanted to produce wines in California in a way that many people thought could not be done. Dan says that this kind of project takes vision because there is no guarantee that anyone in this country will even understand these wines.

[min. 20] Bibiana describes her arrival in Sonoma County in 2005 and she was making wine at the same facility as Jeff, for different labels. They became friends and then got married.

Shared Notes Colombian Coffee

[min. 23] Bibiana has also brought some special Colombian coffee. It is 100% hand grown single origin. The roast is done properly so the smell of coffee is permeating the room. Her two sons are 8 and 10 and she wanted something to connect her family to something positive from her home country. Coffee fits that perfectly. She thought they should start importing green coffee beans and roasting in California. That started in 2019, then in 2022 they started roasting coffee at the winery in Rhonert Park.

Acidity is important for both coffee and wine. Also, both depend on fermentation, since even coffee beans have to be fermented to get the husks off. “I’ve never smelled a light roast with this kind of character,” says Dan Berger.
