The Difference Between Craft and Select Wash Rosin

In the world of solventless concentrates, not all rosin is created equal. At Rosslyn, we press every gram with purpose, from the first wash to the final jar, because how something is made determines how it makes you feel.

You’ve probably seen two tiers across our lineup: Craft Wash and Select Wash. Both are pure, water-separated, solventless rosin, but the difference lies in the starting material, the process, and the experience.

The Foundation: Trichome Quality and Micron Selection

Everything begins with ice water hash, the heart of solventless extraction. When we wash fresh frozen flower, trichomes separate from the plant and are filtered through micron screens, typically between 45 and 159 microns.

Each micron range captures a different trichome size and therefore a different texture, terpene balance, and potency.

Select Wash features refined, balanced trichomes that yield high clarity and smooth flavor.
Craft Wash is pressed from premium-grade trichomes selected from smaller micron ranges, often richer in terpenes and resin density, giving you a deeper, more complex dab.

Think of Select Wash as the daily driver and Craft Wash as the reserve edition pressed from the best of the wash.

Process: Pressing With Precision

Once the hash is collected and freeze-dried, it’s time for the press. Every batch of Rosslyn rosin is pressed at controlled low temperatures to preserve the volatile terpenes that define strain character.

Select Wash Rosin is pressed from the full-spectrum hash, a blend of several micron sizes, to deliver consistent flavor, stability, and accessibility.
Craft Wash Rosin is isolated from the highest-yielding, most flavorful micron fractions, often 73 to 120 microns, producing a richer, more nuanced expression of the cultivar.

The difference isn’t just in the yield; it’s in the texture, the clarity, and the flow of the experience.

Why It Matters

At Rosslyn, “Risen from Water” isn’t just a phrase; it’s the core of what we do. Both washes are solventless, clean, and made from premium indoor material. By dividing our process into these two tiers, we can offer purity without compromise and ensure every session fits your flow.

Whether you’re chasing a calm evening or a creative spark, knowing what’s behind your jar helps you appreciate every gram that much more.
