Could I do this with an Olympia Cremina SL?

"Can" = Yes "Need" = NO Water temperature is very critical for teas as well as americanos. I make my americanos with 7 oz water at 162F in my 8 oz hydroflask. Anything higher kills the flavors. While heating to a set temperature is possible with steam wand, it is just too much fuss. If you don't have
