Chardonnay is a dry white wine that can taste overly acidic or tart to some palates. While Chardonnay is not meant to be an overly sweet white wine like Moscato, there are still several methods you can use to add a touch of sweetness and smooth out the acidity in Chardonnay if desired.
Simple Syrup
One of the easiest ways to sweeten Chardonnay is by using simple syrup. Simple syrup is just equal parts sugar and water heated until the sugar dissolves. When cooled, the syrup can be mixed into Chardonnay a teaspoon at a time until the desired sweetness level is reached.
Simple syrup is flavorless, so it will not alter the overall taste of the wine outside of reducing acidity and adding general sweetness. The amount needed can vary depending on the dryness level of the particular Chardonnay, but a good rule of thumb is starting with a teaspoon of simple syrup per 5 ounces of wine.
Pros
- Very easy to make at home
- Allows customized sweetness
- Does not interfere with wine’s flavor
Cons
- Can water down wine slightly if overused
- Adds empty sugar calories
Fruit Juice
Fruit juice is another easy way to sweeten Chardonnay. White grape juice, apple juice, peach juice and apricot nectar are all good options. Start by adding juice a spoonful at a time until the sweetness tastes balanced.
Fruit juice will add some subtle fruit flavors in addition to sweetness. This pairs especially well with buttery, oaky Chardonnay. The fruitiness helps balance the complexity. Stay away from citrus juices like orange since the acidity will clash.
Pros
- Enhances fruit flavors
- Adds natural sweetness
- Easy to control sweetness level
Cons
- Can dilute wine’s flavor at high amounts
- Natural sugars may ferment over time
Honey
Honey is an all-natural way to sweeten Chardonnay. The floral sweetness and viscosity of honey can help smooth out bitterness and acidity. Stir in honey a half teaspoon at a time until the desirable sweetness is reached.
Pick a honey variety that pairs well with the notes in the Chardonnay. Lighter honeys like wildflower or orange blossom allow the wine flavor to still come through. Bolder honeys like chestnut or buckwheat lend more flavor of their own.
Pros
- Natural source of sweetness
- Varied flavors from different honeys
- Adds texture and body
Cons
- Can overpower wine flavor if added excessively
- Sediment issues if not fully incorporated
Sugar
Plain white sugar can also be used to sweeten dry Chardonnay. Use plain granulated sugar rather than brown sugar. The molasses notes of brown sugar do not pair well with white wine.
Stir sugar into Chardonnay a 1/2 teaspoon at a time until the desired sweetness level is reached. The granules will dissolve with stirring. The maximum recommended amount of sugar is around 1 tablespoon per 750 ml bottle.
Pros
- Readily accessible ingredient
- Easy to add precise amount
- Does not alter other flavors
Cons
- Less complex sweetness than honey or fruit juice
- Potential for overly sweet result
Glycerin
Food-grade glycerin is an odorless, flavorless liquid sugar alcohol that can give added body and sweetness to wine. It occurs naturally during wine fermentation. Adding extra glycerin also helps smooth out bitterness and acidity.
Glycerin will not dilute flavors like plain sugar. Start by adding 1 teaspoon of glycerin per 750ml bottle, tasting after each addition until the desired sweetness is reached. Maximum addition is around 1 tablespoon per 750ml.
Pros
- Does not alter flavors
- Adds smoothness and body
- Helps balance acidity
Cons
- Can have a slick or oily texture if overused
- Not a natural product
Fruit Preserves
Stirring a small spoonful of fruit preserves into Chardonnay can impart natural sweetness along with complementary fruit flavor. Peach, apricot, pear, cherry, and raspberry are good pairings with buttery Chardonnay.
Use preserves that are 100% fruit, without added pectin or filler ingredients. Add just a 1/2 to 1 teaspoon at a time, tasting until the desired sweetness is reached. The chunky fruit texture gives an interesting twist.
Pros
- Provides fruit flavor complexity
- Preserves are easily accessible
- Natural source of fruity sweetness
Cons
- Fruit chunks can be unappealing to some
- Higher calorie than other options
- Potential to negatively affect wine’s clarity
Grape Must
Unfermented grape must or juice added to wine before bottling, called süssreserve in German, imparts natural grape sweetness along with the fruit flavors. White grape must is the best option for sweetening Chardonnay.
Grape must additions must follow certain alcohol and acidity regulations. Home winemakers can add a spoonful of canned or bottled grape must for a similar effect. Concord grape must has very intense sweetness.
Pros
- Natural grape sweetness
- Preserves fruity wine characteristics
- Used in some commercial sweet wines
Cons
- May alter original wine flavor at high amounts
- Less precise sweetness control
- Fresh must availability can be limited
Other Wine Varietals
Blending in a splash of an already sweet wine like Moscato or ice wine can bump up the sweetness level of a Chardonnay. Use a ratio of about 10-15% of the sweet wine to 85-90% of the original Chardonnay.
Complementary fruit flavors like peach, apricot and honeydew melon pair well in sweet blending wines. The added flavors create a complex blend that highlights the original Chardonnay’s character.
Pros
- Complex sweetness and flavors
- Blending allows perfect sweetness control
- Mimics commercial blending methods
Cons
- Need access to appropriate sweet wines
- Can dull Chardonnay character if overblended
- Added fermentation risk from blending

| Sweet Wine | Significant | Complex flavors added | Moderate |
Ideal Sweetness Level
When sweetening Chardonnay, add the sweetening agent gradually and taste as you go. The ideal added sweetness level can vary according to personal preference. In general, just look to take the edge off the tartness rather than make the wine overtly sweet.
For a 750ml bottle, most people enjoy the result after adding around 1-3 tablespoons total of their chosen sweetening agent. Adding too much can make the wine unbalanced and syrupy.
It helps to have a specific sweetness level in mind. On the typical wine sweetness scale, Chardonnay falls around 0-3, with 0 being completely dry and 10 being very sweet. Bumping Chardonnay up to around a 4-6 on the scale by adding a touch of sweetness takes the edge off the acidity without fundamentally changing the wine’s dry character.
Stabilizing Sweetened Chardonnay
Once the desired sweetness of the Chardonnay is reached, the added sugars will need to be chemically stabilized to prevent refermentation in the bottle. There are a couple methods to stabilize sweetened wine:
Potassium Sorbate
Potassium sorbate is a wine stabilizer that inhibits yeast activity and fermentation. To use it, first sweeten the wine to the target level. Next, measure out potassium sorbate at a dosage of 1/2 teaspoon per gallon of wine (2 gallons per 750ml bottle). Dissolve the measured potassium sorbate in a bit of water or wine first, then stir thoroughly into the finished wine. After 24 hours, the wine is stabilized.
Potassium Metabisulfite
Potassium metabisulfite works similarly to stabilize sweetened wine. First, sweeten the wine to the desired level. Then, measure out potassium metabisulfite to a dosage of 1/4 teaspoon per gallon. Stir thoroughly into the wine and seal for at least 24 hours before bottling. The sulfites will prevent refermentation.
Both potassium sorbate and potassium metabisulfite are readily available winemaking additives that inhibit yeast activity once the desired sweetness level is achieved. Following dosage recommendations and allowing proper reaction time provides stable sweet wine.
Storage of Sweetened Chardonnay
Once sweetened and stabilized, Chardonnay should be treated like any other bottled wine for storage. Optimal storage conditions are a cool, dark place around 55°F and 75% humidity. Under these conditions, the wine should retain optimal flavor and aroma for 1-2 years.
As with all wine varietals, sweetened Chardonnay is best consumed shortly after sweetening for maximum freshness and flavor. The additions can shorten the wine’s shelf life slightly compared to completely dry Chardonnay.
Bottles should be stored carefully on their side, not upright, to keep the corks moist and prevent excess oxygen exposure. Consume sweetened Chardonnay within a few months and avoid long term aging for best quality.
Serving Sweetened Chardonnay
Sweetened Chardonnay makes a pleasant, smooth sipping wine that pairs well with a variety of foods. Fruit-forward seafood like scallops or crab cakes works nicely. It also complements spicy Asian dishes well by countering heat. Foie gras and other rich meats make a classic pairing too.
Since residual sugar masks subtle flavors, avoid overly complex dishes that fight with the wine. Simple preparations allow the wine’s fruity sweetness to shine. Serve chilled at 50-55°F.
For entertainment, sweet Chardonnay is enjoyable on its own as an aperitif wine. Its fruity profile and smooth drinkability make it a crowd-pleasing pre-dinner wine. Consider making a spritzer with juice and soda water for warm weather occasions.
Other White Wines to Sweeten
While this article focuses on sweetening Chardonnay, the same methods can work well with other dry white wine varieties too. Good white wine candidates for sweetening include:
- Sauvignon Blanc
- Pinot Grigio
- Riesling
- Chenin Blanc
- Pinot Blanc
- Verdicchio
- Trebbiano
When sweetening any white wine, aim for balance. The sweetness should complement the wine’s inherent flavors, not overwhelm them. Tart, light bodied whites tend to work best with a touch of sugar or other sweetener.
Conclusion
Chardonnay can easily be made sweeter at home by using simple additives like syrup, juice, honey, or sugar. Gradual additions allow perfect sweetness control. chemically stabilizing the wine prevents re-fermentation in the bottle so the sweetness lasts. Serve chilled and enjoy the smoother, fruitier profile.
