Step-by-Step Cold Brew Method

The Classic Immersion Method

This is your foolproof method for home cold brew:

Ingredients:

200g coarsely ground coffee (ratio 1:5 coffee to water)
1 litre cold, filtered water

Instructions:

Grind Your Coffee: Go for a coarse grind like you’d use for French press. If you’ve got a Breville Smart Grinder Pro from JB Hi-Fi, hit settings 25-30 for the sweet spot.
Combine Coffee and Water: Chuck the ground coffee and cold water into a large jar. Give it a good stir to make sure all the grounds get wet.
Steep: Cover it up and let it sit at room temperature for 12-24 hours. Want it stronger? Let it steep longer.
Filter: Strain through a fine mesh with cheesecloth or coffee filters. For super clean results, strain it twice.
Store: Pour into a clean container and stick it in the fridge. Your concentrate will keep for up to 2 weeks.

The Japanese-Style Slow Drip Method

Want to try something different? The slow drip technique creates incredibly smooth cold brew. The Breville Precision Brewer from Harvey Norman has a cold brew setting that does this for you.

Choosing the Right Coffee Beans

Your bean choice makes or breaks your cold brew. Luckily, Australian roasters have some fantastic options perfect for cold brewing.

Best Bean Characteristics for Cold Brew

Origin: Central and South American beans work brilliantly
Roast Level: Medium to medium-dark gives you balanced flavour
Processing: Natural or honey-processed beans add lovely fruity sweetness
Grind Size: Always go coarse to avoid over-extraction

Australian Coffee Roasters for Cold Brew

Heaps of Aussie specialty roasters now do cold brew blends. Check out beans from Melbourne legends like Market Lane or Sydney’s Single O, available through Amazon AU and specialty stores.

Australia’s wild climate affects how you should make and drink cold brew:

Summer Brewing (December-February)

Increase steeping time slightly because of the heat
Go for lighter, more refreshing flavours
Try adding citrus or fruit flavours

Winter Adaptations (June-August)

Try hot cold brew by adding warm water to concentrate
Experiment with spiced variations
Use darker roasts for more warming flavours

Frequently Asked Questions

How long should I steep cold brew coffee?

Sweet spot is 12-24 hours. I’d start with 16 hours and tweak from there. Longer steeping = stronger coffee, shorter = milder. The Breville Cold Brew Concentrate Maker has built-in timers so you nail it every time.

What’s the best coffee-to-water ratio for cold brew?

Go with 1:5 (1 part coffee to 5 parts water) for concentrate, or 1:8 for ready-to-drink. That’s roughly 200g of coffee per litre of water for concentrate. Adjust based on how strong you like it and what beans you’re using.

Can I make cold brew with pre-ground coffee?

Yeah, but freshly ground is way better. If you’re using pre-ground, grab coarse grinds labeled for cold brew or French press. Avoid fine grinds – they’ll make your coffee muddy and bitter. The Breville Smart Grinder Pro from JB Hi-Fi gives you perfect grind control for cold brew.

How should I store homemade cold brew?

Keep cold brew concentrate in airtight glass containers in the fridge for up to 2 weeks. Diluted cold brew should be finished within 3-5 days. Always use clean containers and skip plastic storage – it absorbs odours and messes with the taste.

Why is my cold brew bitter or sour?

Bitter cold brew usually means over-extraction from grinds that are too fine, steeping too long, or dodgy beans. Sour cold brew suggests under-extraction from grinds that are too coarse, not steeping long enough, or wrong ratios. Adjust these one at a time until you hit the sweet spot.
