“This stuff works!
“For the first time, I feel like I get that spring/fall rosin punch during the coldest time of the year.
“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.
“I am able to get the most delicate and raucous of articulations and sound with everything in between.

Never leave your sound behind.
❄ Same Winter formula – 2/3 the size. Clip it and forget it!
The ultimate “in case of emergency” rosin for students and gigging bassists.
How it works
❄ Quick-clip anchors the container securely to your gear. Leave the container attached and take the rosin/lid with you.
❄ Magnetically snaps onto metal music stands or posts for instant access on stage.
❄ Keeps its shape and won’t get all over your hands before or during a performance.
I’m Isaac Trapkus – NY Phil bassist and rosin maker.
In 2019, I began researching and experimenting with rosin to understand how it worked and if it could be improved. I wanted to create one that would:
Excel in winter
Last the whole concert
Never go bad
The more I studied, the more I appreciated what Pops and Kolstein had accomplished decades ago. The challenge was to refine that same lasting grip and response with greater seasonal stability and control.
Five years and more than 100 failed versions later, I launched Winter in 2025 — consistent, stable, reliable.
Easy strokes
Winter is built for balance and control:
- ❄ No scratchy, weak tone from powder.
- ❄ No “chainsaw” tone from overly aggressive rosin.
- ❄ No more getting stuck digging in on a low string.
Compatibility
Winter is great alone, or as a powerful base-layer for your current rosin:
❄ Winter has a less aggressive start on slow or soft notes and responsive grab that kicks in for loud or fast passages.
❄ Get the familiar start-of-note feel of your current rosin with a lasting boost that prevents rosin failure through heavy passages.
❄ Winter does the heavy lifting, so you can get more miles out of your current rosin.
Gum rosin is 80-90% rosin acids. Traditional bass rosins add tackifiers, softeners and other additives that loosen up these acids to increase initial 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 major hurdles.
