What low-cost tea remnants often fill traditional flat tea bags, leading to bitterness?
Answer
Fannings and dust
Traditional, low-cost tea bags are typically filled with tea particles known as fannings and dust. These are the very small, broken remnants generated during the tea production process. Because these particles are fragmented and small, they tend to release their flavor aggressively and very rapidly upon contact with hot water. This aggressive release mechanism often results in flavor profiles that are overly extracted, excessively bitter, or simplified to merely a one-note 'tea dust' taste, failing to deliver the complexity found in higher-quality preparations.
