In general, green tea is the most delicate, while black and herbal teas are more forgiving when it comes to temperature and steeping time.
总的来讲，绿茶和白茶较为精致娇嫩，红茶和香草茶的容错率更高一些。
冷萃取
If you plan to drink your tea iced, cold steeping might be the way to go. Steeping tea in cold to room-temperature water results in a less bitter and more aromatic tea with a higher antioxidant content. However, the lower the steeping temperature, the longer the brewing takes — in most cases, as long as 12 hours.
如果你喜欢喝冷饮，那么冷萃或许是最简单的方式。用室温条件的冷水沏茶，茶的苦味会更淡，香味会更浓，抗氧化成分含量更高。但相应的，水温越低，浸泡的时间就越长，有时可长达12小时。
One study found that steeping at 40°F (4°C) for 12 hours extracts and retains more polyphenols than steeping for 3–4 minutes in hot water. The study also found that steeping for 3–5 minutes at 175°F (80°C) followed by adding ice led to similar taste and antioxidant contents as the 12-hour cold steeping method, making this a quick alternative.
有研究显示，用4℃的水浸泡茶叶12小时，萃取出的多酚比用热水浸泡3-4分钟更多。研究还发现，用80℃热水浸泡茶叶3-5分钟，再用冰块冷却，其味道和抗氧化成分含量和用冷水浸泡12小时相近，是一个效率更高的选择。
工具、技巧和注意事项
While there are special tools to help you steep tea, you can also keep it simple and still steep like an expert.
虽然沏茶的公举很多，有些高端专业，其实用最简单的工具，也能像专家一样沏茶。
At a minimum, you need a teacup, tea bag, and kettle. Place the tea bag in your teacup. Fill the kettle with fresh, cold, and filtered water and bring it to a boil, or a near boil if brewing green or white tea. Then, pour the water over your tea bag in the teacup. Covering the teacup with a saucer is optional, but doing so will help retain more of the aromatic compounds. Steep for about 5 minutes, or to your taste.
最简单的方法需要用到一个茶杯、茶包和一个烧水壶。将茶包放入茶杯，在水壶里倒入新鲜、低温和冷却水，将其烧开，或近乎烧开（对于绿茶和白茶来讲）。然后将热水倒入茶杯，将茶杯盖住，可以保留更多芳香物质。浸泡5分钟左右，便可品尝。
For loose leaf tea, you’ll also need a metal tea ball or infuser to hold the leaves. Measure out 1 teaspoon of dried tea leaves or 1 tablespoon of fresh ingredients per 6–8-ounce (177–237-ml) cup. Place the leaves in the tea ball or infuser and submerge it in a cup of hot water for the proper amount of time.
如果是散装茶，需要用到过滤器。取1茶匙干茶叶，比例为1茶匙：6-8oz（177-237ml）。将茶叶放入过滤器，将其没入热水，用合适的时间浸泡。
Using loose leaves requires a few more tools for steeping, but in return, you have a larger selection of varieties compared with bagged tea, allowing for more combinations of flavor and health benefits.
沏散装茶需要用到的根据多一些，但对茶叶的选择更多，可以为你带来更多风味和健康功效。
For cold-brewed tea, it’s a good idea to make multiple servings in a large mason jar at once because of the long steep time. Fill a jar with fresh, cold water and add 1 tea bag or 1 teaspoon of dried tea in an infuser for every 6 ounces (177 ml) of water.
制作冷萃茶，因为制作时间较长，最好一次性多做一些。在罐子里加入新鲜的冷水，放入1个茶包或1茶匙干茶叶，比例为1茶匙/1茶包：6oz（177ml）水。
