professional grade

I’m Isaac Trapkus – NY Phil bassist and rosin maker.

Weak sound, scratchy tone, and a bow full of powder with no grab. Bass is hard enough and your rosin isn’t helping.

Say goodbye to the extra rehairs and rosin replacing game once and for all.

After 5 years of development (and 100+ failed versions), Winter rosin is consistent, stable, and dependable when every other rosin lets you down.

I handcraft every cake of Winter rosin and continually test new and old batches so you can count on having the same quality I use on stage daily.

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

what's special

The good news:

Gum rosin is 80-90% rosin acids. Traditional bass rosin adds tackifiers & softeners that loosen up these acids to increase grab of the bow on the string.

The bad news:

Over time, bass rosins become 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 is different!

“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!

This stuff works!
Timothy Cobb
Principal Bass, New York Philharmonic

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.
Glenn Gordon
Assistant Principal Bass, Oslo Philharmonic, Norway

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.
Paul Nemeth
Associate Principal Bass, The Florida Orchestra

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.

Grammy Award-Winning Bassist, Los Angeles
