Oolong FAQs

What is Oolong tea?

A semi-oxidised tea that sits between green and black. Processing and roast create floral, creamy or roasted flavours, and the same leaves can be re-infused several times.

Is Milk Oolong naturally milky?

Quality Milk Oolong has naturally creamy notes from cultivar and processing. If flavouring is used we label it clearly.

How much caffeine is in oolong?

Generally between green and black tea. Actual caffeine depends on the leaf and how strong you brew it.

How should I store it?

Airtight, cool and dark. Enjoy greener styles within two years, if stored correctly; roasted oolongs hold up longer.

Can I cold brew oolong?

Yes — 1 tbsp per 500 ml cold water, refrigerate 6–12 hours, then strain. Great over ice.
