When it comes to sweet vermouth, the alcohol content is slightly higher than most wines. This is because vermouth is fortified with additional alcohol, typically grape brandy. The addition of this alcohol boosts the overall alcohol content of the vermouth. However, even with this fortification, sweet vermouth still remains moderately low-proof.
On average, sweet vermouth has an alcohol content of about 15-18% alcohol by volume (ABV). This means that for every 100 milliliters of sweet vermouth, there would be approximately 15-18 milliliters of pure alcohol. To put it in perspective, a typical glass of wine usually has an ABV of around 12-14%, so sweet vermouth has a slightly higher alcohol content.
When enjoying sweet vermouth, it is commonly mixed into cocktails or served on its own over ice. One popular mixed drink is the classic Negroni, which combines sweet vermouth with gin and Campari. Another common serving method is to top sweet vermouth with soda water, creating a refreshing and lower-alcohol beverage.
When you stir sweet vermouth over ice and top it with soda, the resulting drink will have a lower alcohol content compared to drinking it neat or in a cocktail. This is because the addition of soda water dilutes the vermouth, lowering its overall alcohol concentration. As a result, the drink clocks in at approximately 8-10% ABV, making it a lighter option compared to stronger spirits or full-strength wines.
It's worth noting that the alcohol content can vary slightly between different brands of sweet vermouth. Some may have a slightly higher or lower ABV, but the general range tends to be around 15-18%. It's always a good idea to check the label or product description for specific information regarding the alcohol content of a particular vermouth brand.
In my personal experience as a sommelier and brewer, I have found sweet vermouth to be a versatile and enjoyable drink. Its moderate alcohol content makes it suitable for sipping on its own or mixing into a variety of cocktails. The balance of sweetness and herbal flavors in vermouth adds complexity to drinks and pairs well with a range of ingredients.
To summarize, sweet vermouth typically has an alcohol content of about 15-18% ABV. When mixed with soda water, the alcohol content of a drink made with sweet vermouth is reduced to approximately 8-10% ABV. Whether enjoyed in a cocktail or on its own, sweet vermouth offers a flavorful and moderately low-alcohol option for those looking for a refreshing beverage.
