I’m Isaac Trapkus – NY Phil bassist and rosin developer.
In 2019, knowing nothing about rosin making, I set out to develop a bass rosin that would do three things:
- Excel in winter
- Feel and sound great the whole concert
- Never go bad
Solving all three meant learning everything I could about rosin chemistry and usage in other industries.
After 5 years of development (and 100+ failed versions), I had my Eureka! moment. Winter bass rosin is consistent, stable, and dependable.
Winter is trickier to make than traditional rosin, so I handcraft every cake in very small batches and continually test new and old batches to ensure you get the same quality I use on stage.
Over a year since my last rehair and still feeling good!
(Provided voluntarily, without compensation or incentives)
“For the first time, I feel like I get that spring/fall rosin punch during the coldest time of the year. This rosin is a game changer.
“It’s the first rosin I’ve used that doesn’t have issues with consistency, so I don’t have to overthink when to put it on. Powerful but leaves very little residue on the string.
“Best rosin I’ve ever used in my life. I am able to get the most delicate and raucous of articulations and sound with everything in between.
Gum rosin is 80-90% rosin acids. Traditional bass rosins add tackifiers, softeners and other additives that loosen up these acids to increase grab of the bow on the string.
Over time, traditional bass rosin becomes brittle. The rosin acids oxidize and pack down into a tight structure. You can add solvent to re-soften the rosin, but the tacky rosin acids have undergone an irreversible chemical change.
Winter bass rosin solves this problem by giving the rosin acids the space and protection they need and virtually stops oxidation. Think of them as “free-range” rosin acids!
There’s much more to lasting grab than this, but it’s one of the biggest hurdles.
Q. Can I use Winter bass rosin year round?
Yes, as long as your playing spaces are under 80F. Winter solves the problem of bad bass rosin in cold / dry weather but is still good the rest of the year. I didn’t expect this, but it’s been popular in SoCal, TX and FL.
Q. Is Winter bass rosin best by itself or with another rosin?
You will get the greatest range of articulation and sound using it by itself. Some creative bassists use Winter as a base-layer boost with a swipe of Pops (new or old) on top.
Q. Do you ship international (outside USA)?
Check out the international shipping menu next to the “add to cart” button. More countries coming in Fall 2025.
For now, feel free to email me for any international order inquiry and let’s see what’s possible:

Q. Will there be a Summer bass rosin?
I’ve been working on a stabilized version of a certain popular bass rosin for several years. Dialing it in takes a lot of testing and tweaking. Stay tuned!
Is "Winter" rosin for me?
Buy this if...
Your current rosin needs some help in colder / dryer conditions.
You want easy, clear articulation and tone.
You want more playing time between rehairs.
You are a jazz/folk player who needs their bow ready at a moment’s notice through a long show.
You want that extra gear for big musical moments.
Don't buy if...
Winter playing temp is 76°F (25°C) or above.
You are a true beginner, as you may not yet have the bow control and experience to make the most of this rosin.
You are a powder-style player.
You are looking for a solo rosin.
