Not only can you steep teas multiple times, but some teas actually get better the more times you steep them. And not only that, but you also save money because you get to use your tea for much longer. So here is a quick guide on which teas can be steeped multiple times and how to do it. But remember, each tea is unique so this guide will be very basic.

Oolong Tea Can Be Steeped a minimum of 7
For a good quality Oolong, you should get a minimum of 7 steeps out of it. Here is the timing you should use, but remember each tea is unique so this guide is very loose:
1st Steep 1 minute
2nd Steep 30 seconds
3rd Steep 45 seconds
4th Steep 1 minute
Each Additional Steep Add 15 seconds to the previous steep time.

Green Tea Can Be Steeped Up to 3 Times
Green tea is a bit more tricky. The key to making it properly is to be sure your water is around 170 degrees Fahrenheit. If anything, err on having your water too cold than too hot.
1st Steep 1 minute
2nd Steep 1 minute 30 seconds
3rd Steep 3 minutes

White Tea is a Wild Card
There are differing opinions surrounding White tea. Some recommend steeping it once for 15 minutes, while others advise steeping it for less time and doing multiple infusions. With White tea you want to make sure you use enough tea. Since it is so fluffy, many people tend to use too little tea. Here is a general guide for multiple infusions using White tea:
1st Steep 3 minutes
2nd Steep 4 minutes
3rd Steep 6 minutes
4th Steep 9 minutes

Black Tea is NOT Good for Multiple Infusions
Black tea can be steeped multiple times, but you will find it’s flavor quickly disappears. So, if you are going to go for a second steep, increase the time by about 2 minutes.
