When selecting a wine, you will always notice a year like 2018 or 2020 printed on the label. This is the Vintage, which denotes the exact year the grapes were harvested. Unlike mass-produced spirits, a wine's profile and quality fluctuate based on annual agricultural patterns.
Grapes are delicate berries. Excessive rain during harvest dilutes sugars and softens tannins, leading to lighter wines. Conversely, years with abundant summer sun and cool nights allow grapes to reach optimal maturity, yielding Great Vintage bottles with exceptional concentration. These vintages have dense structures suitable for decades of aging.
While Old World wine regions (e.g., Bordeaux, Burgundy) show high vintage variability due to climate fluctuations, New World regions (e.g., California, Australia) enjoy more stable climates, resulting in consistent profiles year after year. Checking vintage charts can help you identify outstanding harvest years for your favorite regions.
