Tasting of different vintages of the same wine, known as vertical tastings, provide a wealth of information in regards to how the wine ages, from which extrapolations into future ageability can be made.
Rosewood Estates had its first vertical tasting of the last five (also the first five) Semillon vintages, to which I was recently invited. This white grape, known for its low acidity and oiliness, is used in production of dry or sweet wines and is commonly grown in places like Bordeaux and Australia and to lesser extend Chile and South Africa. Though Rosewood Estates, together with Angel’s Gate and Stratus Wineries are the only three wineries growing Semillon in Niagara thus far, this variety has undoubtedly set its root-in-the-door and is determined to remain. Planted in 2003, Rosewood began harvesting Semillon in 2006, but it wasn’t until 2008 when a single varietal wine was made.
