One of the questions we receive surprisingly often is:
“Which rosin should I use?”
Many players expect us to recommend a WARCHAL rosin.
The truth is—we don’t make one. And, at least for now, we have no plans to.
That may sound unusual coming from a company that develops strings. But there is a simple reason behind it.
Whenever we decide to create a product, our goal is not simply to add another item to our catalogue. We want it to stand among the very best available. Developing strings has been our passion for decades, and that is where we believe we can contribute the most to musicians.
Rosin is a different story.
The market already offers an astonishing variety of excellent products, each with its own character and strengths. Rather than investing years into developing another rosin, we believe our customers are better served by us identifying and recommending the finest rosins that already exist.
Our Recommendations Have Changed
Long-time readers may remember our Big Rosin Test from many years ago, where we tested forty different rosins.
Since then, the market has evolved considerably.
New manufacturers have appeared. Existing products have been refined. Some of our own experiences have changed after years of working with thousands of musicians in every imaginable climate and playing situation.
As a result, our recommendations have changed as well.
Today we intentionally keep our selection very small.
Not because there aren’t many good rosins—but because we only recommend products we know well enough to trust.
Why We Care So Much About Rosin
One of the most common questions we receive—both from WARCHAL users and players using other string brands—is how to improve a particular aspect of their instrument’s performance.
Sometimes they’re looking for more projection. Sometimes they want a quicker response. Others are trying to reduce scratchiness, improve articulation, or simply make their instrument feel easier to play.
Unfortunately, diagnosing these issues remotely is rarely straightforward.
The instrument itself may be responsible.
The bridge. The soundpost. The strings. The bow. The rosin.
Or simply the way these factors interact with each other.
There are far too many variables for anyone to identify the true cause through email alone.
However, if we can confidently eliminate at least one important variable, finding the real cause becomes much easier.
That is exactly why we invested so much time into evaluating rosins.
Our goal was not to find products to sell, but products we could recommend with complete confidence. When we know a player is using a rosin we trust, we can focus our attention on the many other factors that influence tone and playability.
Our Budget Recommendation: Sandrine Raffin
If we had to recommend just one outstanding value-for-money rosin, it would be Sandrine Raffin from Paris.
It has impressed us with its consistency, reliability and versatility.
Beyond its great tonal qualities, we have consistently found it to perform exceptionally well in environments with very high humidity—conditions where many rosins begin to struggle.
Rather than being highly specialised, it performs well across a wide range of instruments and playing conditions, making it an excellent choice for the vast majority of players.
It offers remarkable performance for its price and represents one of the best bargains currently available.
Our Premium Recommendation: Leatherwood
Finding a single premium rosin that genuinely works equally well for violin, viola and cello is surprisingly rare.
That is one of the reasons why we decided to recommend Leatherwood Rosin.
From Leatherwood’s range, we currently recommend two formulations.
Leatherwood Concerto
Concerto is our most universal premium recommendation.
It provides excellent grip, clear articulation, strong projection and outstanding responsiveness while remaining remarkably consistent under a wide range of conditions.
For players seeking maximum performance and versatility, it is difficult to overlook.
Leatherwood Bespoke 75% Supple
Our second recommendation is the 75% Supple Bespoke formulation.
Compared to Concerto, it sacrifices only a small amount of projection, but rewards the player with a noticeably more forgiving feel.
Many musicians appreciate its smoother attack and reduced tendency towards scratchiness, making it particularly attractive for recording sessions and players looking for a more refined, relaxed response.
There Is No Universal Rosin
Just as there is no string that suits every instrument, there is no single rosin that works perfectly for every player.
Individual instruments behave differently.
Bows differ.
Climate matters.
Playing style matters.
Personal preference matters.
Nevertheless, after years of testing, listening and working with musicians around the world, these are the rosins we trust enough to recommend to our own customers.
Sometimes the best way to serve musicians isn’t by creating another product.
Sometimes it’s by recommending the right one.
