How do I brew this loose leaf mint tea properly to get the best flavour?

For this Emelyanovskaya Biofactory loose leaf tea, start with about one teaspoon (1-2 grams) of leaves per 200-250 ml cup of freshly boiled water. Since it's loose leaf, you have flexibility: use a tea infuser, a teapot with a strainer, or brew directly and pour through a sieve. Let it steep for 5-8 minutes. Loose leaves release their aroma and essential oils more gradually than finely cut tea in bags, which is why the drink can feel more vivid and rounded. You can adjust the strength by using more leaves for a richer mint profile or steeping longer for a more pronounced flavour; taste it as it brews to find your preference. After steeping, remove the leaves to prevent the tea from becoming overly strong or bitter. The water should be just off the boil; very hard rolling boils can sometimes flatten delicate herbal notes.
