The single-vineyard 2022 Nervi-Conterno "Vigna Valferana" Gattinara has not yet been released. Roberto Conterno maintains a strict, extended wood and bottle-aging program for the crus, meaning the estate is currently releasing the flagship 2022 Gattinara blend, while the 2021 Valferana remains the current single-vineyard release on the market. When it eventually debuts, expect Valferana's signature austere, hyper-vertical profile—driven by its high iron and manganese volcanic soils—showing a more rigorous tannic structure and deeper mineral core than the standard bottling.
