With 15,000 bottles made, the 2017 Alto Adige Sauvignon Castel Ringberg is a well-priced and reasonably accessible white wine that delivers on a promise of freshness and varietal purity. Sauvignon Blanc from Alto Adige has those zesty aromas of passion and tropical fruit, but it never reaches the pungent levels of aromatic intensity that you see in this grape from New Zealand, for example. Most of this wine is made in stainless steel with brief lees contact, whereas only 15% is fermented in oak.
