As a long term user of a competitive cello rosin, it was not easy to convince me to try the Kolstein Cello Rosin.

“I love my Kolstein Cello Rosin!  I use it on both my fine bows with my classical cello, and on all four of my carbon fiber bows with my electric cello, with traditional horse hair and synthetic hair.  The grip is wonderful and the cake is a wonderful size.  I also love the beautiful gold packaging!”

tom martin“Dear Barrie,
Just a note to thank you so much for the rosin.
I can see that you really put your heart and soul into perfecting it and I think it is great.
I find it leads one into a slightly different way of bow/string contact which makes playing easier.
I hope this finds you well.”

“I´m using Kolstein rosin with great pleasure. It works very well with all kinds of different repertoire. I´m using it while playing in an orchestra and also when playing concertos.
It gives you a great “bite” but also sensitive and colourful sound.”

From the strongest attacks to the most nuanced articulations this is the rosin that will help provide the greatest range of expression for the music. I use it every day with great confidence and have enjoyed watching it expand my students abilities for many years.”

“I have had a most rewarding experience with the Samuel Kolstein Ultra Bass Rosin – Soft grade. From the the first application to my bow, I was extremely happy with the total response and full-bodied sound I was producing. It has been a long time since I felt this confident about rosin. You don’t need much and it last for days. I am also impressed with the unique packaging with the rubber casing that just rolls down the cake of rosin for easy accessibility then zips back to protect the cake keeping the mold of rosin intact. As you all know, there are tons of rosin to buy, but if you care how you sound, you’ll want to check out the Kolstein Ultra Bass Rosin – Soft grade. ”

“I find the Kolstein violin rosin to be the best rosin I have used in my 35+ years of being a professional fiddler/violinist. It is very unique in that it pulls a very smooth tone from my 4 and 5 string violins but is also capable of having the bite I need that is very controllable. It has great adhesion to the hair. I get much more playing time before I need to apply rosin again. It produces very little dust. I have tried many different brands, and some of them very expensive, but I find Kolstein violin rosin to be the best for me. May I suggest you try some too.”
David Blackmon

“A cake of your rosin is almost always present on my stand (and my colleague’s stands at the Met). With a four-thousand seat house to play to, we have to be able to crank out the sound, and that requires rosin that is going to grab the string dependably.Your rosin delivers, and that’s all there is to it.

Last summer while serving as principal bass of the NY Philharmonic, I called you from Vail, CO needing some Kolstein rosin to revive my over-used bowhair… You kindly Fedexed some out, and saved the day!

Tchaikovsky 4, if I remember correctly..!”

“I was taking a lesson with Tim Cobb the other day and he put some of your newest soft rosin on my bow and I thought it worked really well. I’ve been playing Principal Bass in Charleston, SC these past two years and am looking forward to this season with some of your rosin. Good Job!Tom Bresnick


“After having tried for decades almost every kind of rosin, from famous to less known ones, I came back to an old ‘love’, Kolstein rosin.

Directness and yet warmth in sound, perfect adherence in sustained stroke as well as suppleness when playing bouncing bow stroke make the Kolstein Ultra Formulation Supreme Rosin a must which I recommend to all cellists including my own students.

Kindest regards,

Mirel Iancovici”
