QX: Protected to preserve polyphenols

QX is a limited release of Quartz Hill's most concentrated, medicinal-grade high-polyphenol extra virgin olive oil.

It is independently lab verified at 793 mg/kg polyphenols - three times what the industry usually celebrates as high-polyphenol (250mg/kg). [see lab reports here]

Quartz Hill are Australian polyphenol specialists and use world-class production and protection techniques. As polyphenols are very fragile they must be protected from degradation long after the lab report is published.

Exclusive limit of 500 monthly subscribers.

  • QX is grown, harvested and bottled in the Macedon Ranges on a single estate.

  • 100ml QX = 1L standard supermarket oil.

  • Daily ritual of 1-2 tablespoons.

WHY FOCUS ON POLYPHENOLS?

Polyphenols are the antioxidant compounds in quality extra virgin olive oil that are linked to cardiovascular protection, reduced oxidative stress, gut health, cognitive health and anti-inflammatory benefits.

The European Food Safety Authority requires a minimum of 250mg/kg polyphenols to claim the anti-inflammatory health benefits of olive oil. QX delivers more than x3 that threshold in a single daily tablespoon.

Small format for freshness

  • The ultimate format

    100ml = 1 week
    Very minimal oxygen exposure before the bottle is finished.

  • High-use households

    250ml = 1 month
    Perfect for high-use households.

  • Fresh oil weekly

    5 x 100ml bottles = 1 month
    Ensures a fresh bottle is ready each week of the month, with a spare to take travelling.

CHAIN OF CUSTODY

Every decision between our grove and your kitchen is made to protect the polyphenol concentration.

Early harvest: picked at peak polyphenol concentration
Cold pressed: within hours of picking
Naturally filtered: settled in stainless steel vats. Gravity settles sediment without mechanical filtering
Stored under inert gas blanket: preventing oxygen from degrading polyphenols before bottling
Temperature controlled: stored, bottled and packed in temperature controlled cellars
Bottled monthly at the estate: not warehoused, not aged on a shelf
Protective dark glass: light degrades polyphenols
Lid: Specialty oxygen reducing pouring lid
Small format: encouages a bottle to be finished within a month.

How to take QX

  • Straight or mixed with a big sqeeze of lemon juice.

  • Blend into your morning smoothie. It also helps the delivery of fat-soluble vitamins in green blends.

  • Use as the base of salad dressings.

THE GROVE

Quartz Hill is grown on the ancient volcanic soils of the Victorian Macedon Ranges, a high altitude, cool-climate region that naturally stresses the olive trees which encourages higher polyphenol production and exceptional freshness.

This produces a more robust, fruity & peppery oil with superior stability.
