98 degrees?

Hey all,

So I recently bought a few new David’s Teas, and the black ones say to steep with 98 degree water. I have a tea thermometer from David’s Teas as well, and so far I haven’t been able to get the water that hot. I bring it to a whistling boil in my kettle, but when I pour the water into the cup and take the temp, the hottest I’m seeing on the thermometer is 91 degrees.

Help, please! How do I get it hot enough?

thanks
