You mention the presto percolator does not contain aluminum that touches the coffee. I was going to purchase it from Target when I noticed this in the Q&A:
“A: The perk well and nut in the 02811 coffee maker is made of aluminum for better heating.

I am unfamiliar with percolarors-do the perk well and but not come in contact with the coffee?
