Overview
- German tea experts clarified the common household question by saying that squeezing or agitating a teabag has little to no meaningful effect on final tea flavor.
- The decisive factors for how strong or bitter a cup becomes are the amount of tea used and how long it steeps rather than mechanical squeezing.
- Tannin chemistry drives bitterness: after roughly five minutes of steeping more tannins move into the cup and the tea turns noticeably more bitter without adding more caffeine.
- Commercial teabags are intentionally underfilled so leaves can expand during infusion, which helps flavor develop more fully than in cramped tea‑eggs.
- To avoid drips without changing taste, experts recommend wrapping the teabag string once around a spoon when lifting the bag and note that packaging brewing instructions come from trained “tea tasters” who test hundreds of cups daily.
