Full Definition
Batonnage (lees stirring) involves agitating settled yeast cells back into wine using a stick or mechanical device. This releases mannoproteins and other compounds, adding body, creaminess, and complexity. Common in white Burgundy and quality Chardonnay production. Excessive batonnage can create heavy, oxidized wines.
