Choose by flavour and occasion
Start with flavours you already enjoy: citrus, berries, floral notes or a softer roasted taste. Then check whether the blend contains tea leaves, herbs, fruit or a combination. A flavour name does not tell you the caffeine content or all ingredients. For a first order, choose a smaller quantity before committing to a large set.
Check caffeine beyond the flavour name
Green and black tea, maté and guarana can contribute caffeine to a blend. A fruit name on the front does not prove that a drink is caffeine-free. Read the full list and any caffeine statement. If you need to avoid caffeine, look for an explicit statement for the exact product and ask the seller when it is unclear. Do not infer an amount from the colour of the infusion.
Cold Brew and iced tea are different
Use cold water only for a product explicitly labelled for cold preparation, following its directions. An ordinary fruit or herbal infusion may require boiling water; do not assume it is suitable for cold steeping. For iced tea made from a hot infusion, follow the hot preparation instructions first, then cool and store as directed. Clean the bottle before each preparation.
