Trépail is most famously known for its vast vineyards. The vineyards in Trépail are dominated by Chardonnay. Trépail shares the Chardonnay dominance with three of its neighbouring villages: Vaudemagne and Billy-le-Grand just below the slope, and Villers-Marmery, located to the north/northeast along the slope. This area is sometimes called the Perle blanche, and Trépail is probably the most well-known village of the area. The current vineyard surface in the Trépail commune is just under 700acres. As of 2013, it is made up of about 90% Chardonnay and 10% Pinot Noir.
