Instant Tea
Instant tea is the cheapest and most commercial type of tea sold. Although not very healthy, ( sugar and other ingredients are added in this packing type ), items like Ice Cold Iced tea ( Black tea with lemon and sugar already mixed, dried and pulverized ) are sold to the thousands, especially because of its strong commercial campaign.
Some brands are Tetley and Lipton, the last one being the largest Instant Tea brand sold worldwide.
