Factors Influencing Acidity
Several factors contribute to the acidity level in wine, from vineyard practices to winemaking techniques. Understanding these factors can help you appreciate the nuances of acidity in different wines.
Grape Variety
As we’ve already seen, certain grape varieties are naturally higher in acidity than others. Sauvignon Blanc, Riesling, Albariño, Grüner Veltliner, Pinot Noir, Sangiovese, and Barbera are just a few examples of grapes known for their tartness.
Climate
Cooler climates generally produce grapes with higher acidity. In warmer climates, grapes tend to ripen more fully, resulting in lower acidity and higher sugar levels. This is why regions like the Loire Valley (for Sauvignon Blanc), Germany (for Riesling), and northern Italy (for Barbera) are known for their high-acid wines.
Harvest Time
Harvesting grapes earlier in the season will result in higher acidity levels, while harvesting later will lead to lower acidity and higher sugar levels. Winemakers carefully monitor the acidity and sugar levels in grapes to determine the optimal harvest time.
Winemaking Techniques
Certain winemaking techniques can also influence the acidity of the final wine.
- Malolactic fermentation (MLF): This process converts malic acid (a tart acid) into lactic acid (a softer acid), reducing the overall acidity of the wine. Some winemakers choose to block MLF to preserve the wine’s natural acidity.
- Acidification: In warmer climates, winemakers may add tartaric acid to the wine to increase its acidity and improve its balance.
- Blending: Winemakers can blend wines from different vineyards or varietals to achieve the desired level of acidity.
Pairing High-Acid Wines with Food
High-acid wines are incredibly versatile when it comes to food pairing. Their refreshing acidity cuts through richness, cleanses the palate, and complements a wide range of dishes.
Here are some general guidelines for pairing high-acid wines with food:

What makes a wine acidic?
Wine acidity is primarily determined by the presence of organic acids, such as tartaric, malic, and citric acids, naturally found in grapes. The concentration and balance of these acids contribute to the wine’s perceived tartness, crispness, and overall structure. Factors like grape variety, climate, vineyard practices, and winemaking techniques all influence the final acidity level in the wine. Warmer climates generally result in lower acidity as the grapes ripen, converting acids into sugars, while cooler climates tend to produce grapes with higher acidity.
Winemaking processes, such as malolactic fermentation (MLF), can also alter the acidity. MLF converts the sharper malic acid into the softer lactic acid, resulting in a smoother and less acidic wine. Conversely, adding tartaric acid during winemaking is a legal practice in some regions to boost acidity in wines lacking it naturally. The total acidity and pH of a wine are key indicators of its stability, aging potential, and sensory profile, influencing how it pairs with food.
Which white wines are typically the most acidic?
Several white wine varietals are known for their high acidity levels. Sauvignon Blanc, originating from the Loire Valley in France, is a prime example, often exhibiting vibrant citrus and herbaceous notes with a refreshing zing. Riesling, particularly those from Germany’s Mosel region, showcases a striking balance of sweetness and high acidity, capable of aging beautifully for decades. Albariño, a Spanish white wine from Galicia, offers a bright and zesty character with pronounced acidity, making it a fantastic food pairing option.
Other notable acidic white wines include Grüner Veltliner from Austria, known for its peppery and citrusy profile, and Pinot Grigio, which, while sometimes neutral, can display considerable acidity, especially when grown in cooler climates like Alto Adige, Italy. The acidity in these wines contributes to their crispness, balance, and overall refreshing nature, making them enjoyable on their own or as accompaniments to various cuisines, particularly seafood and salads.
Are there any red wines that are considered high in acidity?
While red wines are generally lower in acidity than white wines, some stand out for their relatively higher levels. Pinot Noir, especially from cooler regions like Burgundy, France, or Oregon, USA, can exhibit notable acidity alongside its delicate red fruit flavors and earthy undertones. Sangiovese, the primary grape of Chianti Classico in Tuscany, Italy, is another red wine known for its pronounced acidity, contributing to its savory character and ability to pair well with tomato-based dishes.
Additionally, Barbera, a red grape variety from Piedmont, Italy, is characterized by its vibrant acidity, low tannins, and bright red fruit flavors. These red wines’ acidity provides structure and balance, complementing their other characteristics and enhancing their aging potential. The perception of acidity in red wines can also be influenced by other factors, such as tannin levels and fruit concentration.
How does acidity affect the taste and mouthfeel of wine?
Acidity plays a crucial role in shaping the taste and mouthfeel of wine. It contributes to the wine’s perceived tartness, crispness, and refreshing qualities. High acidity can create a mouthwatering sensation, stimulating saliva production and enhancing the perception of flavors. It also provides structure and balance, preventing the wine from feeling flat or flabby on the palate. Acidity interacts with other components, such as sweetness and tannins, to create a more complex and harmonious sensory experience.
In wines with high acidity, the flavors tend to be brighter and more pronounced, with citrus, green apple, or gooseberry notes often dominating. The mouthfeel can be described as zesty, lively, or even tingling. Conversely, wines with low acidity may feel softer, rounder, or even bland. The appropriate level of acidity is essential for creating a balanced and enjoyable wine, influencing its overall character and ability to age gracefully.
How does climate impact the acidity levels in wine grapes?
Climate significantly influences the acidity levels in wine grapes. In cooler climates, grapes tend to retain higher levels of acidity because the lower temperatures slow down the ripening process. This allows the grapes to accumulate sugars gradually while preserving their natural acids, such as tartaric and malic acids. The resulting wines often exhibit crisp, refreshing qualities and a vibrant acidity that contributes to their overall structure and balance.
Conversely, warmer climates tend to produce grapes with lower acidity. Higher temperatures accelerate the ripening process, causing the grapes to metabolize malic acid into sugars. This leads to a decrease in acidity levels and an increase in sugar content. Wines from warmer regions are often richer, fuller-bodied, and may have a softer, rounder mouthfeel due to the lower acidity. Winemakers in warmer regions may sometimes use techniques like acid addition to balance the wine’s flavors.
Can you taste the difference between different types of acids in wine?
While it’s difficult for the average wine drinker to pinpoint the exact type of acid present, experienced tasters can often discern subtle differences in the perceived acidity based on the dominant acid. Tartaric acid, the most abundant acid in grapes, contributes a crisp, clean, and slightly bitter taste. Malic acid, often associated with green apples or underripe fruit, has a sharper, more tart flavor. Citric acid, while present in smaller amounts, provides a bright, refreshing citrusy note.
Lactic acid, a product of malolactic fermentation, is softer and creamier than malic acid, imparting a rounder, more mellow character to the wine. Acetic acid, while not desirable in high concentrations, can contribute to a vinegary or sour taste if present excessively. The overall perception of acidity in wine is a complex interplay of these different acids and their interactions with other components like sugars, tannins, and alcohol, creating a unique sensory experience.
How does the acidity of wine affect its food pairing potential?
The acidity of wine is a crucial factor in determining its food pairing potential. High-acid wines work particularly well with rich, fatty foods, as the acidity cuts through the richness and cleanses the palate. This is why crisp white wines like Sauvignon Blanc and Riesling are excellent choices for pairing with seafood, creamy sauces, and fried dishes. The acidity provides a refreshing contrast and prevents the palate from becoming overwhelmed.
Conversely, lower-acid wines may be better suited for lighter, more delicate dishes. Red wines with moderate acidity, like Pinot Noir, can complement earthy flavors and pair well with roasted meats and mushrooms. The acidity in wine also helps to balance sweetness and spiciness in food, making it a versatile tool for creating harmonious and enjoyable dining experiences. Matching the acidity levels of wine and food can enhance the flavors of both, leading to a more satisfying overall experience.
