Is black tea a stimulant or not?
If theine and caffeine are indeed the same molecule, their concentration is not at all similar. Caffeine is much more present and therefore more powerful in coffee, which is considered a stimulant. There is three to four times more caffeine in a cup of coffee than there is caffeine in a cup of tea. Tea therefore has a lighter effect, which is described as stimulating. Note that there are still differences between the different types of tea: black tea is the richest in theine (notably because it releases it more quickly), than green tea and white tea, known as the “lightest”.
Does black tea have a stimulating effect or not?
Present in black tea leaves, theine is released when immersed in hot water. Theine is then considered to be the main active ingredient in tea. In nature, inside plants, theine functions as a natural insecticide, to counter predators. But in humans, theine acts as a stimulant, giving us energy. Without achieving the exciting effect of coffee, black tea gives a little boost. Just what you need to stay awake and alert. Released gradually into the body over six hours, theine boosts concentration and our memory skills.
Can black tea harm sleep or not?
The stimulation felt, the rate of absorption of theine/caffeine, and tolerance will be specific to each person. While the stimulating and energizing effect of black tea is sought by some, because it is considered beneficial, others may, on the contrary, want to do without it. This is the case for people sensitive to theine, who may fear having difficulty falling asleep, and who prefer to drink black tea only in the morning. Another public who may seek to reduce their consumption of theine: pregnant women.
When to drink black tea during the day?

The best time to drink black tea: our opinion
If we have to recommend a time of day, at Kusmi we love drinking a cup of black tea in the morning! Enough to wake up well and have energy all day long.
Just like its cousins green teas and white teas, black tea has many benefits. It is not considered a stimulant but rather a stimulant. Its richness in theine (same molecule as caffeine) and L-theanine are at the origin of this energized calm with which tea is so often associated. Does it prevent you from sleeping? It depends on your tolerance to theine. Every person is different on this point. For some people, it's no problem to drink a nice cup of black tea before bed. For others, stopping must be done in the afternoon at the risk of impacting sleep and falling asleep. Fortunately, several alternatives exist!
