professional grade

I’m Isaac Trapkus – NY Phil bassist, rosin maker, and your cold-weather ally.

I struggled for years with rosin that failed in winter and had to be wastefully replaced every couple months.

After 5 years of research and experiments (and 100+ failed versions), I finally landed on a dependable solution.

I handcraft every cake of Winter rosin and test every batch.

Over a year since my last rehair and still feeling good!

what's special

Disappointing bass rosins:

Bass rosins made by softening gum rosin have short-term grab that quickly dissipates under bowing friction and create clouds of powder – making front-end articulation frustrating in cold / dry conditions.

Great bass rosins:

Leading bass rosin makers know there is much more to sustained grab than softness. Even so, no single formula works for all conditions.

"Winter" bass rosin gives you smooth playability, reliable grip, and clean response — meticulously tailored to excel in colder / dryer playing conditions.
