Health benefits of green tea when cold brewed?

Postby SmidgeDE » May 1st, '12, 08:07

Hi,

I've been wondering if Green Tea has the same health benefits when brewed cold than when brewing it hot?

With cold brewing I mean putting the leaves into a jar with filtered water and leaving them in a fridge for about 12 hours.

It tastes really good and refreshing, but is it just as healthy?

I have no proof and can only go by my very subjective personal feelings

but imo it is not as beneficial as hot brewed (accounting for my daily lifestyle habits)

I dunno maybe it might have real good efficacy after some strenuous exercise in hotter environment, but I really don't strain too hard if at all so couldn't tell you if this might be the case :mrgreen:

Generally speaking, the hotter the water the more the antioxidants are released from the leaves, that is, if you let tea stand.

Here is some further info I found on the web, if it helps:

"Of course, there are pros and cons to brewing tea this way. Cold-brewing will produce a lighter-bodied tea with less astringency and bitterness, as this method draws out a fewer tannic compounds, which is great for a mellow, even sweet, iced tea.

"Cold-brewing is also more time efficient, since you can make a pitcher of tea and store it in the refrigerator for a few days without having to brew a batch every day.  On the flip-side, it is also suggested that cold-brewing will draw out as little as half of the caffeine and half the beneficial antioxidants derived by hot-brewing, but 'research' can’t speak to that. Some suggest that splashing the tea leaves with a little bit of hot water 'opens up the leaves', helping release stronger flavour, more caffeine and higher antioxidant levels."

Why not try eating the leaves to get the benefits?

It’s common knowledge that drinking green tea offers many health benefits, but did you know that further benefits are offered from eating green tea leaves? Using green tea leaves in salads, blending into smoothies or using as a seasoning for foods is a delicious way of getting the nutritional benefits that green tea has to offer as it takes full advantage of the antioxidants and vitamins in the leaves which are not fully extracted during the brewing process. Some components of green tea leaves are not water soluble at all, meaning that you are missing out on them by simply drinking the tea. To draw a comparison, we are encouraged to eat the vegetable and drink the water when we boil vegetables to ensure maximum health benefit. Why should green tea be any different?

Try saving the leaves next time you brew up and sprinkle them into a stir fry or even sprinkle dried leaves on top of ice-cream for a quick and easy way of incorporating green tea into your everyday diet.

In cold brew, Catechins (antioxidant) is extracted slowly. Even after 10 minutes (in the water of 104F), less than 50% of Catechins can be extracted.

Cold brew is healthy, but hot brew is healthier.
