The style of Cabernet Sauvignon is strongly influenced by the ripeness of the grapes at harvest. When more on the unripe side, the grapes are high in pyrazines and will exhibit pronounced green bell peppers and vegetal flavors. When harvested overripe the wines can taste jammy and may have aromas of stewed black currants. Some winemakers choose to harvest their grapes at different ripeness levels in order to incorporate these different elements and potentially add some layer of complexity to the wine.

When Cabernet Sauvignon is young, the wines typically exhibit strong fruit flavors of black cherries and plum. The aroma of black currants is one of the most distinctive and characteristic element of Cabernet Sauvignon that is present in virtually every style of the wine across the globe. Styles from various regions and producers may also have aromas of eucalyptus, mint and tobacco.

As the wines age they can sometimes develop aromas associated with cedar, cigar boxes and pencil shavings. In general New World examples have more pronounced fruity notes while Old World wines can be more austere with heightened earthy notes.

Pairing with food

Cabernet Sauvignon is a very bold and assertive wine that has potential to overwhelm light and delicate dishes. The wine's high tannin content as well as the oak influences and high alcohol levels associated with many regional styles play important roles in influencing how well the wine matches with different foods. When Cabernet Sauvignon is young, all those elements are at their peak, but as the wine ages it mellows; possibilities for different food pairings open up. In most circumstances, matching the weight (alcohol level and body) of the wine to the heaviness of the food is an important consideration. Cabernet Sauvignons with high alcohol levels do not pair well with spicy foods due to hotness levels of the capsaicins present in spices like chili peppers being enhanced by the alcohol with the heat accentuating the bitterness of the tannins. Milder spices, such as black pepper, pair better due to their ability to minimize the perception of tannins—such as in the classic pairings of Cabernet Sauvignon with steak au poivre and pepper-crusted ahi tuna.

Fats and proteins reduce the perception of tannins on the palate. When Cabernet Sauvignon is paired with steak or dishes with a heavy butter cream sauce, the tannins are neutralized, allowing the fruits of the wine to be more noticeable. In contrast, starches such as pastas and rice will have little effect on tannins. The bitterness of the tannins can also be counterbalanced by the use of bitter foods, such as radicchio and endive, or with cooking methods that involve charring like grilling. As the wine ages and the tannins lessen, more subtle and less bitter dishes will pair better with Cabernet Sauvignon. The oak influences of the wine can be matched with cooking methods that have similar influences on the food-such as grilling, smoking and plank roasting. Dishes that include oak-influenced flavors and aromas normally found in Cabernet Sauvignon—such as dill weed, brown sugar, nutmeg and vanilla—can also pair well.

The different styles of Cabernet Sauvignon from different regions can also influence how well the wine matches up with certain foods. Old World wines, such as Bordeaux, have earthier influences and will pair better with mushrooms. Wines from cooler climates that have noticeable vegetal notes can be balanced with vegetables and greens.

New World wines, with bolder fruit flavors that may even be perceived as sweet, will pair well with bolder dishes that have lots of different flavor influences. While Cabernet Sauvignon has the potential to pair well with bitter dark chocolate, it will not pair well with sweeter styles such as milk chocolate. The wine can typically pair well with a variety of cheeses, such as cheddar, mozzarella and brie, but full flavored or blue cheeses will typically compete too much with the flavors of Cabernet Sauvignon to be a complementary pairing.
