Spearmint's charm is in its restraint: sweet and mellow rather than sharp, with a cooling finish that never tips into the bitterness some mint infusions carry. The first sip is smooth, the aroma light, and there's a faint fruitiness under the mint — Teatico's tasting notes for this one run from lemon and honey through herbs, mint, peppermint and spearmint itself, with a medicinal edge on the back end. It's a gentler cousin to peppermint tea. Spearmint (Mentha spicata) and peppermint (Mentha × piperita) are different plants — peppermint is actually a hybrid of spearmint and watermint — and spearmint's menthol content is a fraction of peppermint's, which explains why it reads as soft and rounded where peppermint reads as sharp and medicinal. That makes spearmint the better choice when you want mint in the background of a cup rather than the whole point of it.
It's naturally caffeine-free, so it works at any hour without touching sleep. People tend to reach for it after meals, when the mint plays well with a full stomach, or in the evening as a wind-down cup that won't keep anyone awake. It has long been drunk as a digestive aid and for a general sense of calm, though those are traditional uses rather than proven effects.
To brew it, pour freshly boiled water over the leaves — fresh or dried both work — and let it steep for around ten minutes; shorter if you want something lighter, longer if you like it strong, since the flavour builds steadily rather than turning harsh. Strain and drink it plain, or add honey or lemon, both of which echo notes already in the cup. It holds up hot or cold: chill it after brewing and pour over ice for a summer version. Dried leaves keep best in an airtight container away from light and heat; fresh leaves are worth using within a week for the fullest flavour.
