Food Engineering/Manufacturing/Iced tea botteling

Question
Hi Jim,

I'm trying to make a ready to drink line of organic iced teas.
I have the blends and the containers ready to go - I tried the hot fill method:
brewing the teas @ 70 degrees C for 30 mins and bottled hot and cap right away.
But was wondering if that's the best and safest way to increase shelf life,  
Or is there a different method I can use?
Would cold brew work in that case? if so how will I go about to pasteurize it?

Thank you!

Answer
Ron,
Hot fill is the way to go.  Equipment prices for aseptic or cold brew are way, way higher.

BTW, when bottle is just filled and capped, make sure it's inverted so the heat sterilizes the cap as well as the container.

You should also cool the filled bottles down to at least 30DegC to keep flavor and color loss minimal.
