Hourglass Teatime set of 3 for green, black and herbal tea - every cup brewed to perfectionWhile the black tea has developed its full flavour, the green tea already tastes bitter and the herbal tea is still bland. When brewing tea, there are worlds of flavour between individual minutes. The Küchenprofi Tea Time hourglass is perfectly designed for this. The time runs in three clearly coloured tubes: 3 minutes for green tea, 5 minutes for black tea and 7 minutes for herbal tea. The Tea Time Trio is also practical when different types of tea are served at breakfast or dinner. Tip: When making green tea, leave the water to cool for five minutes after boiling. This also prevents a bitter flavour.
