Instant tea Edit
In 1946, Nestle USA introduced the first instant tea, Nestea.[13] Instant teas are produced from black tea by extracting the liquor from processed portion of tea typically from offgrade black teas; green tea in a smaller proportion has traditionally been used by the instant tea makers as a "clarification agent" - again, in effort to maximize the clarity of color and minimize off-colors created by certain teas that cloud. The extract is concentrated under low pressure, and drying the concentrate to a powder by freeze-drying, spray-drying, or vacuum-drying. Low temperatures tend to be used to minimize loss of flavor. The American market for instant tea powders, which developed quickly following Nestle's introduction, has slackened off considerably over the past quarter century, as Americans have more and more turned to naturally icing their favorite loose teas, as well as preparing iced tea from tea bags, and to ready-to-drink iced teas where the smaller sizes are found in the supermarkets' refrigerated drinks sections and the larger gallon sizes are found in the supermarkets' non-refrigerated drinks sections.
