On the left: regular green tea. On the right: microwave boosted. Not that you can tell from the picture.
Itís been a rough news week, and itís only Wednesday. Fortunately, though, todayís raging controversy is about tea. Is it okay to microwave it? Is it better to microwave it? Australian research says yes, while tea aficionados worldwide recoil in horror.
- Boil water, and pour it over your tea bag. Steep at least 30 seconds.
- Put the cup (with teabag) into the microwave for one minute at half power, or whatever power setting will get you 500 watts.
- When you remove the tea bag, dunk it up and down ten times and then squeeze it out.
The idea is to help people get the health benefits of green tea, without having to guzzle five or more cups a day. Regular brewing can extract 62 percent of the tea leavesí catechins and 76 percent of the caffeine. The microwave boost gets you up to 80 and 92 percent. Thatís not a huge difference, but hey, itís something.
So how does it taste? I brewed two cups of plain green tea, letting one steep for three minutes and doing the microwave protocol, which took about three minutes anyway. I dunked and squeezed both tea bags as I removed them.
They tasted almost identical, although I could detect a little more of a bitter and astringent taste in the one that had been microwaved. Vuong and crew write in their paper that tea brewed this way can be a little stronger, so you may want to use a flavored green tea instead of a plain one, to cover up any tastes you donít like.
One problem: I donít love green tea. And a lot of the British outlets reporting on this study are probably with me on that. Black tea is probably what theyíre thinking of. So I brewed some more tea for science, this time a mango-chili flavored black tea. Again, they were similar but the microwaved tea was slightly more bitter and astringent. It also had more of the chili flavoring, which was nice.
If you are fussy about how you prepare your black tea, you probably know that steeping it too long can make it bitter. Flavor-wise, this technique is just a quicker way to steep it too long. That said, itís not bad. If youíre already the kind of person who steeps a teabag for more than five minutes, or who might even use the same teabag more than once (which my favorite fancy cafť actually recommends, so spare me the ďhow dare youĒ), youíll like this just fine.
