Its really nothing very secretive.... most if not all hot tea
formulaes (not just lipton) are not suited for adding ice to it,
briefly it has something to do with oxidation. If you wanna test it
out, if u put alot of ice immediately into a very hot cup of tea, u
will see the cloudiness almost immediately but leave the tea to
cool and then add ice, the cloudiness will somehow set in later,
but no matter what it will still become cloudy and thus not many
food outlets use hot tea formulaes to do ice tea cos it has no
presentation in terms of colour. Most ice tea u see food outlets
serving are using tea pouches or tea bags that are specially made
for ice tea, as for whats so special....thats a trade secret
hahaha....
