Which pruning system is exclusive to Meunier and adapted for spring frosts?

• A. Vallee de la Marne
• B. Chablis
• C. Cordon de Royat
• D. Guyot

Answer: (A)

Pruning systems that protect against spring frosts must influence when and how buds break, especially for Pinot Meunier, which is particularly frost-prone in some Champagne areas. Vallée de la Marne is a Meunier-specific approach developed in the Marne Valley to guard against late frosts. It uses a very open, cut-back form that limits how many buds can break and delays shoot growth, so the vulnerable young growth is less exposed to freezing temperatures. This adaptation leverages Meunier’s growth characteristics and the local climate, making it distinct from other pruning styles. The other terms refer to different pruning or training concepts that aren’t exclusive to Meunier or specifically tailored for frost protection. Cordon de Royat is a cordon training system used with multiple varieties; Guyot is a general pruning system applicable to many grapes; Chablis is a renowned wine region, not a pruning method.
