While I'm certainly not an expert on brewing white tea, I have stayed in Holiday Inn Express!!
I drink a really nice Pai Mu Tan from Metropolitan Teas at work. I put a nice "load" into my stainless infuser and brew with water from the commercial coffee machines - hot water tap - I've never taken the temp but I'd guestimate 180-190.
I appreciate that I can basically "forget" about the mug while taking calls and still get a nice cup.
I just finished a first infusion after lunch today -- probably steeped about 5-6 minutes.
