I want to start a project and company that serves English tea to the
masses, without the need of tea bags.

I am thinking urns are the way to go, but people have put me off by
saying the tea gets stewed and the urns are difficult to maintain.

After searching around the Internet, I was wondering if you at
rec.food.drink.tea have
any pointers in my quest.

There must be a machine or method that those big popular Ice Tea
canned beverage companies utilise...

Kind regards,
