And then you have time to come to grips w/ the more 'mature' smell of your jacket. 
and another:Leather smell (typical)
Caused by bark tannage, formerly the main tanning method, i.e. tannage by vegetable tanning agents such as extracts of oak, chestnut, pine, quebracho, mimosa, myrobalans or gambir. As they were mostly used in combinations, the leather smell was a more or less strong mixture of one or other of the tanning agents used.
A further odour was introduced by the additional use of natural fatliquoring agents such as train oil, degras, moellon, neatsfoot oil or tallow. Chrome tannage as well as synthetic fatliquoring agents and retanning agents have been used to a greater extent over the past decades, especially for furniture and uphostery leathers.
As a result many fastness properties of the leathers were improved, but the typical smell of leather was lost. Many attempts have been made to bring this smell back into the leather without using vegetable tanning agents. A great number of odorous substances of the cosmetic and perfume industry was used, e.g birch tar oil, pine oil, spruce turpentine, pine-needle oil, wood turpentines, camphor oil, bitter almond oil, cedarwood oil, benzaldehyde and special leather covering perfumes of unknown composition.
The most favourable method of treatment is spraying odorous substances onto the grain and flesh side of the leather prepared for finishing. Addition to top coats is also possible. Application in wet processes (fatliquoring, retanning, dyeing) has not proven useful as the volatility of the odorous substances is increased by subsequent hot air drying.
The amount to be used depends on the desired intensity of smell. All odorous substances have in common that they possess a more or less pronounced vapour tension, meaning that they are always volatile. It may take some days or at best some weeks until the smell has disappeared completely, depending on the adsorbing properties. Since a lasting effect has not yet been observed, there are natural limits to the use of odorous substances.
This makes it difficult to re-create using a topical application.Leather has undergone a huge transformation since Babe Ruth grabbed a ball glove or Buffalo Bill threw a leg over a saddle. The tanning processes of the old days were found to be quite environmentally unsound, so new leather preparation techniques had to be developed. As it turns out, what most of us think of as that "leather smell" is not really the leather itself, but was the residue of the old tanning processes; when the processes changed for environmental reasons the smell went away, so the scientists had to find a way to artificially re-introduce that familiar, friendly smell of leather.
English Leather? 
Well you know how they used to cure leather!
