Can you cold steep rooibos?

[Cofftea]

I've tried it before, and it works great. Am I still getting the nutrients?

Anybody know?

if the flavor is there, so are the health benefits.

I've only done it once and found it doesn't steep well cold. If I'm feeling like a cup I'll make extra and just let it sit and cool, stick it in the fridge (bag in) and transfer to a bigger container in the morning. It's stronger that way.

I've done it a few times for two parties thus far, steeping each batch in the fridge three to four hours before serving/straining. It keeps well when constantly cooled but it does far, far better when steeped similiar to sun teas (mason jar + tea + outside in the sun all day = beauty) as room temperature water become saturated with tea/minerals/etc quicker than chilled as per basic chemistry. Of course, cold steeping in a sealed container gets fewer of the heat-activated ingredients ingrained in other teas though I'm uncertain as to any differences with rooibos as it tastes and looks the same no matter my steeping method. That's a bit of research that I've never searched for nor considered, let alone thinking that a study has been conducted on it. Ah well, there's my experiences.
