Questions tagged [tea]

Questions about the selection and preparation of tea leaves and beverages.

There are several types of tea, which all come from the same plant (Camellia sinensis). They vary in the way they're grown and processed after harvest:

  • Black tea is allowed to wilt and fully oxidize before drying. It is typically prepared in boiling water.
  • Green tea is dried before it can wilt or oxidize. It is typically prepared with substantially cooler water, as low as 140°F/60°C.
  • Oolong tea is allowed to wilt and partially oxidize. It is typically prepared with slightly below boiling water.
  • White tea is allowed to wilt but not oxidize. It is typically prepared in approximately 180°F/82°C water.

All types of tea are often combined with herbs and other flavorings to make beverages like mint tea or chai. Often milk, honey, or sugar are added to the tea after steeping.

There are also steeped beverages from plants other than Camellia sinensis:

  • Tisanes, also known as herbal teas, include mint, hibiscus, anise, lemon grass, rooibos, etc.
  • Coffee, made from the beans of several plants in the genus Coffea.
  • A traditional South American beverage made from the plant Ilex paraguariensis.

How to make a sauce based on tea

I have some pu-erh tea, and I love the smokiness of it. I was thinking about trying to incorporate it into a dish somehow. Specifically, I was thinking about using something like pacific cod. Then I could potentially create a sauce or a rub for it.…

Remove tannins from tea without removing caffeine

I have a lovely black tea that is fairly high in caffeine, which I'd like to keep. Unfortunately though, I'm not a fan of the bitterness caused by tannins, and I'd like to remove them if possible without leaching the caffeine as well. I was thinking…

Does the type of strainer built in a teapot matter?

I have been making tea in a simple glass jug for several years, but I happened to break it. When I went shopping, I saw many teapots with integrated strainers, which look convenient. But there was a large difference between the strainers. Some were…

Is it necessary to rinse Chinese or other tea before first brew / steep / infusion?

I've been told that I should be rinsing Chinese tea with the boiled water before the first full infusion intended for drinking. I make the occasional very-expensive tea from Taiwan and I feel it is a waste to throw away a first pot simply for…

Why is my green tea brown?

As Crystal Gale once wrote, "You're gonna make my green tea, brown." Or something like that. When I typically order (the free or close-to-free) green tea at Japanese restaurants, it's usually noticeably green. At home, regardless of brand and time…

Advantages of using a non-glass teapot?

I currently have a borosilicate glass teapot. Glass seems to have the advantage that it will not absorb flavours and so can be used for all styles of tea. What are some of the advantages of using a clay or ceramic teapot over glass? I am not…
