The red and white grapes for Sergio Germano’s Alta Langa sparkling wine, and almost all of his white grapes, come from plantings in an entirely separate area from the rest of his vineyards. Some years ago, Sergio went looking for an area not too far from his vineyards in Barolo, but better suited to white and sparkling wines, and he found it just outside the village of Cigliè, at the southern tip of the Dogliani appellation. The vineyards here are at 500 meters (1,800 feet) or more above sea-level, steeply sloped, and consist of almost white limestone-rich clay with a lot of stones. He now has more than 10 acres of vineyards in Cigliè and is making vibrant and intriguing wines from grapes grown there and transported back to Serralunga, about 30 minutes away, to be vinified. (Higher altitude tends to bring cooler nights, which allows the fruit to retain more acidity, making it perfect for fresh whites and sparkling wines.)
