Does anybody know much about this? Had a chemical engineer tell me there is no chemical reaction between Brewed tea and sugar. I contend there must be SOME chemical interaction of some type when you add the sugar to the hot brewed tea thus the flavor diference of brewed sweet tea verses adding sugar later. This came about durring a dinner at a supposedly classy resteraunt . When I asked for sweet tea and the waitress told me there was sugar on the table . When I asked her If I would also have to add sugar to their cake when she brought that she seemed confused!I pointed out that the suger needed to be cooked to flavor correctly and then we got into the discussion!
