Pigeage is a traditional French winemaking technique used during fermentation, especially for red wines. It involves the manual “punching down” of the grape skins that float to the top of the fermentation vessel. This process helps submerge the skins back into the liquid, allowing for better extraction of color, flavor, and tannins. By ensuring the skins remain in contact with the fermenting juice, winemakers achieve a deeper, richer flavor profile in the final wine.
The term pigeage comes from the French verb “piger,” which means “to punch.” Historically, winemakers used long poles or paddles to punch down the cap, which is the layer of grape skins, seeds, and stems that forms during fermentation. Nowadays, the process may still be done manually in small-scale or artisanal winemaking, or through mechanical means in larger wineries.
Why Is Pigeage Important?
During fermentation, carbon dioxide is released, causing the grape skins to rise to the top of the fermenting vat. If left undisturbed, this cap can dry out and lead to poor flavor extraction. It can even develope unwanted bacteria. Punching down ensures that the cap stays moist and that the wine absorbs the maximum amount of desirable compounds from the skins.
The frequency and intensity of pigeage vary depending on the style of wine that you make. For lighter wines, winemakers might punch down the cap gently and less frequently, while for more robust wines, the process happens several times a day with more force. The result is a wine with greater structure and complexity, making pigeage a crucial step in producing high-quality red wines.
In modern winemaking, some producers opt for alternative methods, like pump-overs, where you pump the wine over the top of the cap. However, pigeage remains a preferred method for those aiming for traditional, handcrafted wines with deep flavors and rich textures.
