Science be damned ... I still like love to brew tea in a big glass jar outside in the sun!
Can't beat the sun for getting this job done!: organic earl grey, mango passionfruit, fusion green & white, and chai green tea (which doesn't need alot of brew time, btw.), red tea chai. Not all at once in the same jar, mind you, but I have tried various mixtures of bags on different brews. Fun!
Do you do-the-brew-outdoors too?
So far I've never been sick making tea this way & I'm talking 35 years here, folks!
Turn that fan to high and lemme sip away!
