Why is Bottled Tea Level 2 on average?
The gap between brewed tea and bottled tea is one of the largest processing jumps in any food category. Brewed tea is water passed through leaves, one step, one ingredient. Bottled tea manufacturers brew tea in industrial quantities, but the tea itself is often a minor component. Sodium hexametaphosphate, a chemical sequestrant used in industrial water treatment; appears in many bottled teas to prevent cloudiness and mineral precipitation during storage. This compound has no equivalent in home tea brewing. Citric acid adjusts acidity for preservation, and "natural flavors" replace the volatile aromatic compounds that dissipate during industrial processing and shelf storage.

Frequently asked questions
Is bottled green tea healthy?
Unsweetened bottled green tea with just tea and water is about as simple as bottled tea gets and retains some antioxidant compounds. However, many commercial bottled green teas add sugar, honey, or artificial sweeteners, citric acid, and preservatives, which makes them more processed. Always check the ingredient list.
Is Arizona iced tea ultra-processed?
Arizona Green Tea with Ginseng and Honey contains high fructose corn syrup, honey, citric acid, natural flavors, and ascorbic acid. Although labeled as green tea, HFCS is the primary sweetener. A 23oz can contains 51g of sugar. Search Arizona to see its own score.
What is the least processed bottled tea?
Unsweetened bottled teas listing only "brewed tea" and "water" are the least processed. Look for that short list on any brand, including store brands. Brewing your own tea is simpler still.
Why does bottled tea taste different from brewed tea?
Industrial bottled tea loses volatile aromatic compounds during pasteurization and storage. Manufacturers compensate with "natural flavors", concentrated flavor extracts that approximate fresh tea taste. This is why bottled tea needs additives that home-brewed tea does not.
