If you’ve never heard of Sudachi before, you’re not alone.
This small Japanese citrus is relatively unknown in Australia, but it’s highly prized in Japan for its intense aroma, bright acidity and incredible versatility in the kitchen.
At Vast Harvest Permaculture, Sudachi has become one of our favourite citrus varieties and the star ingredient in our handcrafted Sudachi Marmalade.
What is Sudachi?
Sudachi is a small citrus fruit originating from Japan. While often compared to lemons, limes and yuzu, it has a flavour all of its own.
The fruit is highly aromatic, with a fresh citrus fragrance and a tangy juice that can brighten almost any dish. Its unique flavour has made it a staple ingredient in Japanese cooking for generations.
What Does Sudachi Taste Like?
Sudachi has a bright, tart citrus flavour with floral notes and a refreshing aroma.
Many people describe it as somewhere between a lime, lemon and yuzu, although its flavour is distinctive enough to stand on its own.
The juice is intensely flavoured, meaning a little goes a long way.
How to Use Sudachi
One of the things we love most about Sudachi is how versatile it is.
Use fresh Sudachi juice:
In sparkling water for a refreshing citrus drink
Over seafood and grilled fish
In salad dressings and marinades
In baking and desserts
In cocktails and mocktails
Anywhere you would normally use lemon or lime
The zest is also highly aromatic and can be used to add flavour to cakes, biscuits, sauces and preserves.
The Citrus Behind Our Sudachi Marmalade
Many of our customers first discover Sudachi through our handcrafted Sudachi Marmalade.
The bright citrus flavour of the fruit creates a marmalade that is sweet, tangy and packed with character. It’s delicious spread on toast, served with scones, paired with cheese or used as a glaze for meats and vegetables.
If you’ve enjoyed our marmalade, trying the fresh fruit is a great way to experience the unique flavour that makes it so special.
A Special Harvest in 2026
Like many fruit trees, Sudachi crops can vary from year to year.
Last season we barely harvested any fruit at all, with the birds enjoying most of the crop before we had a chance to pick it.
This year has been a completely different story.
Our trees are absolutely loaded with fruit and, for the first time, we have such a large harvest that we’re able to share fresh Sudachi with our customers.
Fresh Sudachi will be available seasonally through our website and at our local stockist, Crafty Friends.
Grown in Our Food Forest
Our Sudachi trees are grown right here in our food forest at Vast Harvest Permaculture.
Each fruit is grown naturally amongst the diversity of our food forest and harvested by hand when ready.
Because fresh Sudachi is rarely available in Australia, this is a unique opportunity to experience one of Japan’s most loved citrus fruits straight from the tree.
Try Sudachi for Yourself
Whether you’re looking for something different for your kitchen, want to experiment with Japanese citrus, or simply love trying unusual fruits, Sudachi is well worth discovering.
Fresh Sudachi is available for a limited time during the 2026 harvest season, along with our handcrafted Sudachi Marmalade made from fruit grown right here on our farm.
Once you’ve tasted it, you’ll understand why this little citrus has become one of our favourite discoveries.
