Why Organic


Harris Organic - the only certified organic vineyard in Perth.


Why Organic

We believe that our children should have clean air and fertile soil so that even the children of our children and so on can prosper. We believe in the care of animals. We believe that art and science can provide a better future for us and our children.
We believe in caring for the soil our grapes grow in to make the best possible wines. We believe that with minimal inputs, incredible wine can be made.

What is organic wine?

Organic wine starts in the vineyard.

By enhancing soil biodiversity and maintaining its fertility, the grapes can truly thrive. By keeping our estate free of harmful chemicals, pesticides, herbicides, and chemical fertilisers, our land is not only better for the grapes today but also tomorrow. The only irrigation our grapes receive is what’s generously donated by the sky; we don’t use any artesian water on our vines here.
During processing, we only add natural yeast to our ferments and use the lowest possible amounts of preservatives and additives. See this Additive List for the chemicals that we DO NOT use in our wine. Every wine is made with a truly organic approach and is fermented, matured, and bottled right here on the premises.
We love what we do and we’re confident you will taste the difference.

Wine Additives

We never use unnatural wine additives in our wines and that’s why we believe we make the best organic wines.
Our wines are suitable for vegetarians, vegans and low sodium diets.

Our shiraz, malbec, and preservative-free dessert wines are unfined and unfiltered, making them as natural as possible.

All our grapes are also grown to the specification of Australian Certified Organic, so you can enjoy pure wines without any herbicide or pesticide residues.

Though many additives are legal and commonly used in Australian wines, we never use any of the following additives:

  • Activated carbon
  • Agar
  • Alginates, calcium and potassium salts
  • Argon
  • Calcium carbonate
  • Calcium tartrate
  • Carbon dioxide
  • Cellulose
  • Collagen
  • Cupric citrate on a bentonite base
  • Diatomaceous earth
  • Dimethylpolysiloxane
  • Egg white
  • Gelatine

Vegan wines: Vegan wines are generally unfined and unfiltered, with no animal additives and, if filtered, are filtered using only sterile, ceramic filters or cross-flower filters. Be sure to check with the producer about filtering techniques as several mass-produced wineries use sterile filters rather than animal products.

Some wineries use bentonite clay instead of isinglass and other animal products in order to fine protein from white wines. Biodynamic wines can be made in a vegan way when they are unfined, but since the farming process uses animal bones for special compost mixtures, it negates this.

If a wine is certified organic, it doesn’t guarantee it’s vegan. Please ask when visiting any cellar door or read the back label for information.
