What's your water quality like the other 2 weeks of the month :tongue2:?Fortnightly we have very good water. It just a few days from the snow pack and springs of the Cascade mountains. We have used that carafe for nearly 10 yrs with NO mineral build up. Nor is there any mineral build up in the https://www.amazon.com/dp/B00006F2MI/?tag=pfamazon01-20 itself. It is a vacuum carafe so the coffee does not get cooked after brewing, ie no heat is applied to keep it warm.
I cannot taste any difference from pre clean to after clean. We are currently using cheap a$$ Costco beans, I may go get some good http://www.sivetzcoffee.com/" beans to see if they taste better. The difference is $5/lb vs $10/lb.
