Bâtonnage, also known as lees stirring, is the practice of gently stirring the wine while it rests on its fine lees (dead yeast
cells) during barrel aging, using a long metal rod called a "bâton" to suspend the lees and increase their contact with the liquid, thereby promoting autolysis and the release of mannoproteins that enhance mouthfeel, texture, and aromatic complexity; this technique is most commonly applied to white wines, particularly Chardonnay and Sauvignon Blanc, as well as to some red wines, and it can add creamy, nutty, and biscuit
notes, while also preventing reductive off-aromas; in poetry, bâtonnage can symbolize the act of revisiting and revising, gently stirring the sediment of memory or language to bring buried meaning to the surface, a patient, rhythmic labor that transforms the wine's body over time, much as careful editing strengthens
a poem's final form.
