Winter
bass rosin
Long-lasting punchy articulation and clean sound through the toughest conditions.
Get Winter
" This stuff works!
For the first time, I feel like I get that spring/fall rosin punch during the coldest time of the year.
Handled Swiss winter with no problem, including an outdoor Christmas gig in the snow!
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.

"Rosin that lasts forever is a terrible business idea."
— Everyone
Traditional bass rosins dry out in cold/dry conditions, making a clear, powerful sound impossible.
Winter stays good year after year.

The Story
Bassment Rosin
I'm Isaac Trapkus, a bassist in the New York Philharmonic.
Bassment Rosin takes my professional bass career and lifelong habit of taking on overly complicated projects and melts them together.
Watch the demo — hear the difference.
I started researching how rosin works and naively assumed it would be pretty easy to make a great one. I wanted a bass rosin that would excel in winter, last the whole concert, and never go bad.
attempts
There's almost nothing written about making bass rosin, so this was a long process of trial and error based on what I could learn about the endless varieties of resins used in other industries. The more I studied, the more I appreciated what Pops and Kolstein accomplished decades ago.
Winter almost didn't happen. I came up with the formula in late spring 2024 and gave a sample to a friend. It seemed a little too soft during the summer, so I'd given up on it. Then in late fall, my friend calls and says "You gotta try this!" After more positive reviews from my colleagues, I launched Winter — consistent, stable, reliable.
