Whole cluster fermentation imparts unique characteristics in Pinot Noir and all red wine, as it allows the grapes to create some alcohol in their cells without the addition of yeast (referred to as “intracellular fermentation”), giving them distinct fruity aromas. ATPGroup has a range of products that can be used at.
Carbonic maceration-fermentation without remove stem. You can gain light wine with good color and low tannin. Thermovinification-whole cluster is treated by hot air or steam. Because color polymerize and precipitate in bottom, long aged wine has no benefits; 10 (No Transcript) 11 (No Transcript) 12 (No Transcript) 13 Must Correction. 1.Acidity problem.
This creates CO2, which then tapers off the traditional fermentation and results in carbonic maceration of the remaining grapes. Generally speaking, the resulting wines are very fruit, light in acidity and short lived. In whole cluster fermentation there is a certain percentage of whole clusters present during the initial stages of fermentation.
Objective: To explore the organoleptic differences between a whole-cluster fermentation versus the same amount of stems added back. Summary: We fermented one tank with 25 percent whole-cluster (75 percent destemmed) and an identical tank with 25 percent stems added back (100 percent destemmed). In each case, the stems or whole clusters were at.
Carbonic maceration is a winemaking technique, often associated with the French wine region of Beaujolais, in which whole grapes are fermented in a carbon dioxide rich environment prior to crushing. Conventional alcoholic fermentation involves crushing the grapes to free the juice and pulp from the skin with yeast serving to convert sugar into ethanol.

We analyzed the effect of whole cluster fermentation (WC) at rates of 50% (50% WC) and 100% (100% WC) and of dried stem additions (DS) on Pinot noir (clone 777) from the Edna Valley AVA of California Central Coast. Wines were produced at industrial scale with treatments replicated three times in two consecutive vintages.
Part V: Winemaking Process. STUDY. PLAY. 1. What effect(s) can acetic bacteria have on wine?. Adopting the same concept as whole cluster pressing used for the production of white wine, whole cluster fermentation is used for red wine grapes. what step is skipped in the Whole cluster (bunch) fermentation process compared to the whole bunch.
Whole Berry fermentation. This episode is all about the use of whole berry fermentation in red winemaking. I used this opportunity to make a solo podcast and go over what whole berry fermentation is, the reasons a winemaker would want to employ this technique in a winery, and also the multitude of challenges that it presents.
Whole cluster pressing (foregoing the step of crushing and destemming the grapes) is most often done to make high-end white wines. The technique creates a more delicate and less astringent wine by reducing the contact time with the stems and skins. Jason Burrus is the Winemaker for Chrysalis Vineyards in Middleburg, Virginia. He has a master’s degree in viticulture and enology from UC-Davis.
Every step in crafting our Pinot Noir is done with careful consideration. The grapes are harvested at night to fully capture their elegant fruit flavors and hand sorted to insure only the finest fruit goes into the fermenter. We use a gentle method of whole berry and whole cluster fermentation to maximize fruit aromatics and complexity.
