The Intricate Art Of Cologne Notes: Understanding Fragrances Better

what are cologne notes

Cologne notes, or fragrance notes, are the individual components of a cologne that, when combined in a certain concentration, create an overall scent. These notes are classified into three categories: top notes, middle notes (heart notes), and base notes. Each note plays a specific role in the cologne's development and longevity, with top notes being the scents you smell first, heart notes forming the heart of the cologne, and base notes providing depth and warmth. Top notes usually consist of lighter and smaller molecules, such as citrus or fruity scents, while heart notes are full-bodied and aromatic, and base notes are rich, heavy, and long-lasting.

Top notes: the first scents you smell after spraying, usually citrus or floral

Top notes are the first scents you smell after spraying a fragrance. They are also known as head notes and they form the top layer of a fragrance. These scents usually consist of lighter and smaller molecules and evaporate quickly, lingering for only the first five to fifteen minutes. Their main purpose is to give off an initial scent and then transition smoothly into the next part of the fragrance.

Citrus scents are commonly used as top notes, such as lemon, orange, and bergamot. These scents can be combined with herbal or woody notes to create a brighter and more modern scent. Bergamot, in particular, is an integral part of the classic Eau de Cologne formula. Other popular top notes include light floral scents like lavender and rose, as well as basil and anise.

Top notes play a crucial role in setting the first impression and shaping the overall story of a fragrance. They are carefully selected by perfumers to create a pleasing and harmonious olfactory experience.

Heart/middle notes: the 'heart' of the fragrance, appearing after the top notes fade

Heart notes, also known as middle notes, are the scents that emerge as the top notes start to fade, usually after a few hours of wear. They are the 'main character' of a perfume, making up around 40-80% of the final fragrance. They are the longest-lasting notes, typically remaining evident for the full life of the fragrance, and lingering on the skin for 6 to 8 hours post-application. Heart notes are often a mix of full-bodied, aromatic floral oils such as jasmine, geranium, neroli and ylang-ylang, as well as spices like cinnamon, pepper, cardamom and pine.

Heart notes are crucial in shaping the perfume's character and allure. They build on the initial impression of the top notes, retaining some of their aroma while introducing new scents to deepen the experience. They also act as a buffer for the base notes, which may not smell as pleasant on their own.

For example, a floral fragrance will have floral heart notes such as rose, jasmine or lily of the valley. Clive Christian's Vanilla Orchid perfume from the Noble Collection is a beautiful illustration of this, with its heart of explosive floral notes balanced by a sweet vanilla base and woody undertones.

Base notes: the foundation of the scent, providing depth and warmth

Base notes are the foundation of a fragrance, providing depth and warmth. They are rich, heavy, and long-lasting, lingering on the skin for six hours or more. These notes kick in after about 30 minutes, working with the middle notes to create the scent's essence. They are the final layer of a fragrance and the ones that sink into your skin, leaving a lasting impression.

Base notes include vanilla, amber, musk, patchouli, moss, and woody notes like sandalwood and cedarwood. These notes are deep and rich, appearing more prominently once the top notes have dissipated. They are less volatile than the other notes, meaning they are less likely to evaporate quickly.

The base notes are crucial in creating a balanced perfume. While the top and middle notes are more noticeable, the base notes provide an underlying aroma that enhances the other notes and gives the fragrance a longer lifespan.

The base notes are carefully selected by perfumers to ensure the fragrance smells pleasant and evokes a particular experience. They are an essential part of the perfume-making process, adding depth, warmth, and longevity to the scent.

Citrus notes: fresh and uplifting, often found in top notes

Citrus notes are inspired by or recreate the scent of citrus fruits. Their zesty, refreshing character makes them ideal to wear in the spring and summertime. These scents are generally captured by extracting the essential oil from the fruit's peel, its leaves, or its blossom. Citrus notes are rather volatile and are often used in the top opening notes to add freshness to a fragrance.

Citrus fragrances are typically combined with other fragrance families such as floral or woody to add more layers of complexity and to anchor the citrus perfume notes, as they tend to have a volatile nature. The floral fragrance family is the most used in perfumery, taking essential oils from a huge variety of flower varieties. When citrus notes are paired with florals, they make a great spring-like perfume through the combination of the freshness from the citrus and the sweetness of flowers, evocative of the blossoming time of year. Woody notes are useful to combine with citrus notes due to their heavy weight, which 'anchors' the more volatile citrus notes. Combining citrus and woody notes create a perfume that is zesty and fresh yet deep, exotic, and sophisticated. These perfumes are perfect if you are fond of citrus scents but want something that lasts longer at cooler times of the year.

Citrus notes are often referred to as hesperidic accords, in reference to the Garden of Hesperides in Greek mythology; a garden where magical golden immortality-giving apples grew, guarded by the daughters of Hesperus, or the God of Evening, the Hesperides. Native to China and Southeast Asia, citrus fruits were brought to Southern Europe by the Arabs. They quickly became a popular ingredient in perfumery, especially in the 18th century with the invention of Aqua Admirabilis in Italy (a blend of bergamot, neroli, lavender, and rosemary) and its better-known successor, the traditional Eau de Cologne.

Citrus-based fragrances are easy to wear and are equally suited to men and women. They range from pure lemony citrus blends to more complex blends featuring woody, floral, or even oriental notes. Bright and crisp, citrus fragrances are perfect for spring and summer.

Woody notes: warm and earthy, often found in base notes

Woody notes are an essential component of colognes and perfumes, adding depth, warmth, and an earthy tone. They are derived from various parts of trees and plants, including bark, roots, resins, and leaves. Woody notes are typically found in the base notes of a fragrance, providing a long-lasting impression. Their rich and heavy nature makes them a popular choice for men's colognes, but they are also used in unisex and women's perfumes.

Woody notes can be categorised into several subfamilies, each with its own unique characteristics:

  • Dry Woods: This subfamily includes notes like vetiver and cedarwood, which offer a dry, earthy, and sometimes smoky scent. Cedarwood, extracted from coniferous trees native to regions like the Mediterranean and the Himalayan Mountains, has a distinctive woody and resinous aroma. It is a staple in men's fragrances and adds a grounding quality to perfumes.
  • Mossy Woods: Oakmoss and patchouli fall into this category, providing a damp, rich, and slightly sweet aroma to the fragrance.
  • Resinous Woods: Notes such as frankincense and myrrh belong to this subfamily, adding a balsamic, sweet, and often slightly spicy undertone to the cologne or perfume.
  • Creamy Woods: Sandalwood is the prime example of this subfamily, known for its soft, smooth, and milky scent. It is a versatile base note that blends seamlessly with floral, oriental, and fresh compositions. Indian Mysore sandalwood, though rare and precious, is highly prized in high-end perfumery.

Woody notes play a crucial role in crafting memorable and enduring fragrances. They provide a foundation that harmonises with other notes, creating complex and long-lasting scents. Whether it's the creamy smoothness of sandalwood, the exotic mystery of oud, or the earthy richness of vetiver, woody notes add depth and sophistication to colognes and perfumes.

They usually consist of lighter, more volatile molecules and evaporate quickly. Common top notes include citrus scents like lemon and bergamot, as well as light floral scents. Heart/middle notes make up the "heart" of the cologne and appear as the top notes start to fade. They last longer than top notes and can include full-bodied floral oils like jasmine and cinnamon. Base notes are the longest-lasting notes and provide depth and warmth to the cologne. Examples include woody scents like sandalwood and musk.

You can identify cologne notes based on the time passed after applying the cologne. Top notes are the ones you smell immediately, heart/middle notes kick in after the top notes start to fade, and base notes are the ones that linger for the longest.
