Is It Safe to Reheat Your Tea in the Microwave?

If you’re anything like me, making a cup of tea is a day-long project. At the risk of sounding like a total grot, I’m going to admit that I often forget about my tea, then reheat it in the microwave.

I don’t know why. It’s a character flaw that we can get into at some other stage. But I’m certain I’m not alone in my tea forgetfulness.

For that reason, I thought I’d take a look into whether or not we should be microwaving our daily cuppa. Is this habit kind of bad for you? Here’s what the experts say.

Is it bad to reheat my tea?

There are loads of opinions around on whether or not microwaving your water gives a consistent enough temperature. Some say no, others say “eh”.

What was particularly interesting to me, however, is the thought that this act could be exposing you to nasty bacteria.

I spoke with a representative of Pukka tea, Beth Howlett, who shared that while it’s definitely down to personal preference, it’s best not to reheat your cuppa too many times.

“We generally recommend limiting the number of times the tea has to cool down, as not only would the flavour and quality diminish, but as with any wet food the risk of bacteria growth increases the more the tea is left sitting unused over time (particularly if it is lukewarm),” she advised.

“That being said, here at Pukka we’re big fans of high-quality tea, so I can’t say it gets re-heated often! A fresh cup is always the way to go.”

Howlett’s recommendation? Pop your tea bag (or leaves) in a cup of boiling water, and let it infuse for five minutes.

Another point of note, shared by Good To Know UK, is if you’ve bought your tea (or any hot drink) don’t reheat it in the takeaway cup. The outlet quoted Dr Laura Vandenberg, assistant professor at the University of Massachusetts Amherst, who advised that the polyethylene (PE) plastic that often lines these cups can harmful to the body when heated.

Good To Know also referred to the UK’s Food Standards Agency, which shared that food and drink should never be reheated more than once because of bacteria growth – much like Howlett advised.

Long story, short: it’s best to drink hot tea the first go around. Best not to mess about this forgetting and reheating technique I am so guilty of.
