Our Winemaking Philosophy Our winemaking philosophy at O’Shaughnessy Estate winery is to produce wines that express the unique character of our Estate vineyards and their appellation. The winemaking style is contemporary, utilizing cutting edge fermentation equipment paired with natural, hands-on winemaking. Our emphasis is on balance; the concentrated nature of the grapes from our estate vineyards needs to be in balance with the flavors and aromas in order to produce the most harmonious wine.
