Is Cold Brew Tea Good for You?
Antioxidants, hydration, low caffeine, zero added sugar — the full picture on cold brew tea and health.
Six Health Advantages
Natural Antioxidants
Tea leaves naturally contain polyphenol antioxidants that help fight free radicals. Green tea catechins (EGCG), oolong polyphenols, and black tea theaflavins each offer distinct properties.
Effective Hydration
Water in tea counts fully towards your daily intake. The natural fruit flavours of cold brew tea make hydration enjoyable — research shows flavoured drinks encourage people to drink more.
Lower Caffeine
Cold water extracts caffeine slowly. Each 500ml contains 20–45mg — far less than coffee (80–120mg), making it gentler for caffeine-sensitive individuals or evening drinking.
Zero Added Sugar
Sosia Tea uses only natural tea leaves and fruit botanicals — no added sugar or artificial sweeteners. All sweetness comes entirely from the natural ingredients.
Smooth & Easy to Drink
Cold water extracts fewer bitter tannins, creating a smoother taste. This makes cold brew tea approachable even for those who usually dislike plain tea or coffee.
Natural Ingredients Only
No artificial colours, preservatives, or flavourings. Sosia Tea uses quality tea leaves and real fruit botanicals — you know exactly what you are drinking.
Tea Antioxidants: Cold Brew vs Hot Brew
Tea leaves are rich in polyphenol compounds — natural antioxidants the plant produces to protect itself. The key ones are: catechins (especially EGCG — epigallocatechin gallate) in green tea, oolong polyphenols, and the theaflavins and thearubigins formed during black tea fermentation.
Research is mixed on whether cold brew retains more antioxidants, but the general consensus is that cold brew retains comparable antioxidant levels to hot brew. Some studies suggest cold brew may preserve catechins better, as high temperatures can degrade certain heat-sensitive polyphenol compounds.

Cold Brew Tea & Daily Hydration
Many people struggle to reach the recommended 2000ml of daily fluids — simply because plain water is boring. Research shows that naturally flavoured drinks significantly increase voluntary fluid consumption.
Cold brew tea provides an ideal solution: full hydration value, natural fruit flavours that make drinking enjoyable, and zero added sugar with minimal calories. Keep a bottle in the fridge and hydration becomes effortless.
