This balance of old and new ensures vermouth remains a versatile and evolving craft.
1. Past Aging Methods
Storage Techniques
Traditionally, vermouth was aged in oak barrels, a practice that dates back centuries. French producers were among the earliest to notice that ageing vermouth in oak after fortification improved both its stability and flavour depth. The porous nature of oak allowed for gradual oxidation, which not only enhanced the drink's complexity but also helped maintain its quality over time.
The climate of the region played a big part too. In places like the United Kingdom and northern Europe, cooler temperatures slowed down the ageing process. This slower maturation resulted in subtler flavour integration, allowing the herbs and spices to blend harmoniously with the base wine. It was this slow and steady process that gave traditional recipes their distinctive character.
Herb and Spice Effects
Older vermouth recipes took a more focused approach to botanicals, with wormwood being the star ingredient. Unlike many of today's recipes that use a wide array of botanicals, earlier versions were much simpler. As Badenhorst observed, traditional vermouths were often "quite simple probably - fruit-based, with one or two spices".
Ageing allowed the botanicals to fully integrate with the wine base. The oak barrels created an ideal environment for the herbs and spices to merge into a cohesive flavour profile. This careful integration was crucial for balancing the medicinal qualities of the botanicals with the overall taste.
Taste Results
Ageing in oak barrels added layers of flavour, including hints of vanilla and caramel, while the slow oxidation process rounded out the palate. Traditional vermouths were known for their oak-induced complexity, pronounced spice notes, and a smoother texture, all of which set them apart from unaged versions.
Though it required a lot of time and effort, barrel ageing was seen as essential for crafting high-quality vermouths. This painstaking process laid the groundwork for the standards of excellence that continue to inspire modern vermouth production.
2. Current Aging Methods
Storage Techniques
In modern vermouth production, stainless steel tanks have become the go-to choice. Unlike oak barrels, which can introduce oxidation and alter flavours, stainless steel preserves the fresh botanical essence of the vermouth. These tanks are often temperature-controlled, allowing producers to maintain precise conditions that prevent spoilage and ensure consistent maturation.
Herb and Spice Effects
Today's vermouth makers use advanced techniques to extract flavours and carefully time macerations, resulting in complex and distinctive profiles. Some recipes feature an impressive mix of botanicals, with ingredient counts ranging between 30 and 47.
Take Badenhorst, for example. They use Chenin Blanc and Muscat de Frontignan as the base wines, blending them with up to 47 botanicals. Their solera system incorporates 20% of older batches, striking a balance between seasonal variation and consistency.
Local sourcing is another focus for some producers. James Christopher Tracy, for instance, sources 30–45 ingredients from within a 13–16 kilometre radius of their winery. This approach combines respect for tradition with a commitment to seasonal and locally inspired practices. These advanced extraction and sourcing methods play a key role in shaping the final flavour.
Taste Results
The result of these modern aging methods is vermouth with cleaner, more defined flavours. Stainless steel storage allows the base wine and botanicals to take centre stage, free from the influence of oak. This controlled process also enhances the stability and shelf life of the product.
Producers like Asterley Bros in London are blending modern precision with traditional techniques, creating vermouths that stand out and appeal to today’s more discerning drinkers. While these contemporary vermouths retain their freshness for longer, proper storage is still essential. Refrigerating the bottle after opening helps preserve the intricate botanical flavours crafted through these refined aging methods.

FAQs
How do traditional and modern ageing techniques influence the flavour of vermouth?
How Ageing Methods Influence Vermouth's Flavour
The way vermouth is aged has a huge impact on its flavour, with traditional and modern techniques each bringing their own character to the drink.
In the past, vermouth was often aged in large wooden casks. This method encouraged the development of deep, oxidised flavours like dried fruit, nuts, and warming spices. The result? A rich, layered profile that showcased the craftsmanship and time-honoured techniques of its era.
Modern ageing takes a different approach, often using stainless steel tanks. These tanks are designed to maintain the freshness and vibrancy of the botanicals, resulting in vermouths with brighter, more aromatic flavours. This technique produces a lighter, more contemporary style that appeals to those who enjoy a fresher taste.
Both methods bring something special to the table, offering distinct sensory experiences to suit a variety of tastes. Whether you prefer the complexity of tradition or the brightness of modernity, there’s a vermouth style for everyone.
