Dry sift hash is produced by gently separating trichomes from dried hemp flowers using fine mesh screens. Trichomes are the microscopic resin glands that contain the plant’s cannabinoids, terpenes and aromatic oils.

When hemp flower is carefully agitated across these screens, the resin heads break away and fall through the mesh as a fine golden powder often known as kief or pollen.

This resin can then be:

• left loose as CBD pollen

• lightly pressed into soft hash

• or refined further into graded dry sift hash

The key advantage of dry sift extraction is that it preserves the natural terpene profile of the hemp flower, producing a concentrate that reflects the character of the original plant.

The Dry Sift Process Explained

The traditional dry sift process involves several key stages designed to collect the cleanest resin possible.

1. Carefully cured hemp flower

High-quality dry sift begins with well-cured hemp flower rich in trichomes. Flowers with dense resin coverage will naturally produce more sift.

2. Gentle mechanical separation

The dried buds are lightly agitated across fine mesh screens. As the material moves across the screen, the brittle trichome heads break away from the plant matter.

3. Resin collection

The resin glands fall through the mesh and collect underneath as a fine powdery concentrate.

4. Grading by micron size

Different mesh sizes are used to separate resin of varying quality and purity.

This is where micron grading becomes important.

What Does 90 Micron (90u) Mean?

In dry sift extraction, the micron rating refers to the size of the mesh used in the screen.

A micron (µm) is one thousandth of a millimetre.

For example:

90 micron screens are widely considered the sweet spot because they allow full resin glands to pass through while filtering out most plant material.

The result is a cleaner, more terpene-rich concentrate with:

• lighter colour

• smoother texture

• stronger aroma

• higher cannabinoid concentration

Why 90u Dry Sift Hash Is Considered Premium

High-quality 90 micron dry sift hash is prized because it contains a high percentage of intact trichome heads, which hold the majority of the plant’s cannabinoids and terpenes.

Compared with lower-grade sift, premium 90u dry sift typically shows:

• light golden colour

• soft, sandy texture

• strong aromatic terpene profile

• clean melt and smooth character

This is why 90u dry sift is often referred to as “full-spectrum resin” — it retains much of the natural complexity of the original hemp flower.

Why Dry Sift Remains a Favourite Hemp Concentrate

While newer extraction methods exist, dry sift continues to be valued for its simplicity and authenticity.

Because the process uses no solvents or chemicals, the final product stays very close to the natural resin produced by the hemp plant.

For many hemp enthusiasts, dry sift offers a concentrate that captures the true character of the flower it comes from.

Final Thoughts

Understanding the dry sift process and micron grading helps explain why certain hash varieties are considered higher quality.

When produced carefully, 90 micron dry sift CBD hash represents one of the most refined forms of traditional hemp resin — combining purity, terpene richness and natural cannabinoid and oil content.

Products like CBD Hash Gold Dry Sift 90u showcase exactly what makes this extraction method so respected: clean trichomes, preserved aroma and a beautifully golden resin profile.
