Hi there,

Ive just started roasting my own coffee. *I replaced my old drip coffee brewer with a Technivorm brewer and bought a Baratza Virtuoso grinder. *Technivorm came with a stainless steel vacuum carafe. *I noticed the coffee tasted a bit harsh after being stored in the vacuum carafe for 30 to 60 minutes. *My old uninsulated glass carafe did not effect the taste so much. *I concluded it must be due to the interaction of the coffee with the stainless steel. *However, after further thought, Im thinking the difference may be due to the temperature storage of the coffee. *The stainless steel carafe keeps the coffee at a higher drinking temperature whereas the open glass carafe cools the coffee quickly to room termperature.
Now, I use the glass carafe for brewing the coffee and place it on the stone countertop which cools it quickly. *I reheat the coffee in the microwave for a second cup and notice it tastes fairly close to the first cup.
Have you folks noticed a difference in your coffee using different materials for storage or storage temperatures?
