Ice wine is a gem in the wine world, famous for its sweet and powerful flavor, as well as its complex production process. Originating in cold climates, this type of wine stands out for its unique production method, which involves harvesting frozen grapes to achieve a concentrated and unparalleled flavor. In this article, you’ll learn what ice wine is, its origin, the different types that exist, and how it’s produced. We will also address some frequently asked questions about this exquisite wine.
Definition and Origin of Ice Wine
What is Ice Wine and How is it Made?
Ice wine, also known as “Eiswein” in German, is a sweet wine made from naturally frozen grapes on the vine. These grapes, when frozen, concentrate their sugar and flavor content, resulting in an intensely sweet must when pressed. For a wine to be considered “ice wine,” the grapes must be harvested at temperatures around -7°C or lower, ensuring they are fully frozen.
The production of ice wine is a delicate and high-risk process, as it greatly depends on climatic conditions. When harvesting and pressing the frozen grapes, only the water remains in the form of crystals, while the sugar and other components remain in the must, resulting in a sweet and concentrated wine.
History and Origin of Ice Wine
Ice wine production originated in Germany in the late 18th century, in the Franconia region, where grapes were not harvested before the arrival of winter. Winemakers took advantage of this opportunity to press the frozen grapes, and to their surprise, the resulting wine had exceptional sweetness and complexity. This method was perfected in Canada, where cold temperatures consistently allow for ice wine production every year.
Types of Ice Wine
White Ice Wine
White ice wine is the most common type, made from white grapes such as Riesling, Gewürztraminer, or Chardonnay. These wines have a sweet and fruity flavor, with notes of honey, peach, and apricot, due to the high concentration of sugars in the frozen grapes. White ice wine is ideal for pairing with desserts or as an aperitif wine.
Red Ice Wine
Although less common, red ice wine also exists, made from red grapes like Cabernet Franc or Merlot. This wine has a sweet character with notes of red fruits like cherries and raspberries, along with spicy hints. Its production is more limited, making it a more exclusive and appreciated option among wine lovers.
Ice Wine Production Process
How are Frozen Grapes Grown and Harvested?
The process begins in the vineyards, where grapes are left on the vine until the first frost. This means that winemakers must take the risk of possible damage to the grapes due to adverse weather conditions. The grapes are harvested by hand at dawn, when temperatures are low enough to keep them frozen. This process is arduous and requires speed to avoid the grapes thawing before being pressed.
Fermentation and Aging of Ice Wine
After harvesting, the grapes are carefully pressed while still frozen. Only a small amount of concentrated must is extracted, which makes ice wine so valuable and expensive. This must then undergoes a slow fermentation process due to its high sugar content. After fermentation, the wine can be aged in oak barrels to add complexity to its flavor, although many producers prefer to bottle it young to preserve its freshness and sweetness.
Characteristics of Ice Wine
Ice wine is characterized by its natural sweetness, high acidity, and complex flavors. Notes of ripe fruit, honey, and flowers are predominant, making it an ideal drink to pair with desserts or to enjoy on its own. The high sugar concentration gives it a dense and silky texture on the palate, while its acidity balances the sweetness, preventing the wine from feeling cloying.
Additionally, this wine has exceptional longevity, meaning it can be stored for many years without losing its unique characteristics.
