What is the Typical Alcohol Content in Mirto?
The alcohol content in Mirto, expressed as Alcohol by Volume (ABV), is not a single fixed number but rather a specific range defined by tradition and regulation. For Mirto di Sardegna, the protected geographical indication (GI) specifies an ABV range of 28% to 36%. However, it is most common to find commercial Mirto bottled at around 30% to 32% ABV. The final percentage is influenced by several factors, including the sugar content, the type of spirit used for maceration, and the production process itself.
Historically, homemade Mirto recipes, which are cherished family traditions in Sardinia, often resulted in a higher alcohol content. Artisanal producers also have more flexibility within the legally defined GI range. The balance between the potent, fruity-herbal infusion and the final proof is what gives each brand or batch its unique character.
Factors Influencing Mirto's Alcohol Strength
The alcohol content of Mirto is not determined by a single variable. A combination of the following elements contributes to the final potency of the liqueur.
Commercial vs. Homemade Production
- Commercial Mirto: Producers of commercial Mirto must adhere to strict regulations, especially for products bearing the "Mirto di Sardegna GI" designation. This ensures consistency in the final product's quality and alcohol content, which is typically standardized for the market. Mass-produced versions are often sweeter and smoother to appeal to a wider audience, which can sometimes result in an ABV on the lower end of the official range.
- Homemade Mirto: Those who create their own Mirto, a common practice in Sardinia, have full control over the recipe. They can use a higher ratio of myrtle berries to alcohol or less sugar, resulting in a more potent, and sometimes more rustic, finished product. These variations are a testament to the drink's deep cultural roots and the personal touches passed down through generations.
Production Method and Ingredients
- Maceration Process: Mirto is produced by macerating myrtle berries (for Mirto Rosso) or leaves (for Mirto Bianco) in ethyl alcohol. The duration and temperature of the maceration period affect how much of the plant's essential oils and flavor compounds are extracted, which in turn influences the final liqueur's character and potency.
- Sweetening: After maceration and filtration, a sugar syrup or sometimes honey is added. The amount of syrup added directly impacts the final ABV. Less sugar results in a stronger, drier liqueur, while more sugar creates a sweeter, less alcoholic product.
- Aging and Variation: Some Mirto varieties are aged in barrels, which can also affect their final character and alcohol level. Barrel-aged versions, like Mirto Barrique, may have a higher ABV and a more complex flavor profile.

This range is legally defined for products with the protected Mirto di Sardegna GI. The precise strength is influenced by the production method—whether it is a commercially standardized product or a high-proof homemade batch—as well as the specific ingredients and the ratio of berries to spirit.
