Powdered Grape Tannins: Enhance Structure and Complexity in Your Wine

Powdered grape tannins are an essential additive for winemakers looking to enhance the structure, mouthfeel, and aging potential of their wines. Derived from grape skins, seeds, and stems, these tannins play a crucial role in balancing flavours, adding astringency, and improving the overall complexity of your wine. Whether you’re making a robust red or a delicate white, powdered grape tannins can help you achieve a more refined and well-rounded final product.

How Powdered Grape Tannins Are Used

Powdered grape tannins are typically added during the fermentation or aging process, depending on the desired effect. When added during fermentation, they can help stabilize colour and provide a firmer structure to the wine. When used during aging, they contribute to the wine’s body and enhance its ability to age gracefully. The tannins also help protect the wine from oxidation, ensuring it remains fresh and vibrant over time.

Key Benefits

• Enhance Structure and Body: Tannins contribute to the wine’s structure, giving it a firmer, more substantial mouthfeel.
• Improve Aging Potential: By adding tannins, you can help your wine develop more complexity and character over time, making it ideal for long-term aging.
• Balance Flavour Profile: Tannins add astringency that can balance out the sweetness and acidity in your wine, resulting in a more harmonious flavour profile.
• Stabilize Colour: Particularly in red wines, tannins help stabilize the colour, ensuring your wine retains its rich, vibrant hue.

Dosage and Application

The amount of powdered grape tannins to use depends on the style of wine and the desired outcome. As a general guideline:

• Red Wines: Use 1/4 to 1/2 teaspoon per gallon (3.8 litres) of wine during fermentation or aging.
• White Wines: Use a smaller amount, around 1/8 to 1/4 teaspoon per gallon, as whites require less tannin structure. Dissolve the tannins in a small amount of warm water or wine before adding them to the batch, ensuring even distribution.

Why Use Powdered Grape Tannins?

Powdered grape tannins are a valuable tool for winemakers who want to create wines with greater depth, structure, and aging potential. Whether you’re enhancing a robust red or adding a touch of complexity to a white wine, these tannins help bring out the best in your brew.
