Say goodbye to
the winter blues
Winter
bass rosin
Long-lasting punchy articulation and clean sound through the toughest conditions.

" 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.

— Everyone
Traditional bass rosins dry out in cold/dry conditions, making a clear, powerful sound impossible.
Winter gives you responsive grip that never gives up.

About Bassment Rosin
I'm Isaac Trapkus — bassist in the New York Philharmonic.
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.
Failed versions. 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 "this is really good — you should sell this one." In January 2025, I launched Winter — consistent, stable, reliable.
