Black tea is a classic option for starting a brisk morning, ending lunch, or calmly ending the day. Thanks to the process of complete fermentation of tea raw materials, the drink has a noble rich color and a pronounced bright taste. The presence of caffeine in the composition provides a mild tonic effect, and a rich list of vitamins and minerals soothes, normalizes blood pressure and neutralizes harmful microorganisms. Black tea is brewed at a temperature of 90-95°C. The highest quality varieties do not lose their taste when re-brewing. The quality of the drink is determined by the size of the tea leaf: the highest grades are tea from whole leaves. The better its shape is preserved (the tip of the leaf is present), the higher the classification.
