The most common type of bubble tea is milk tea. It depends on the recipe, but it can include non dairy liquid or powdered creamers to whole milk, or alternative milks to condensed milks. Fruit tea also varies, as there are milk-based fruit teas. Fruit teas, on the other hand, are usually infused with real fruit or have fruit syrup added to them. Consider your standard passion fruit or mango teas combined with a black tea or green tea base.
