i take a big thermos full of coffee everyday. realized today that my coffee today was much better than yesterday. i use cafe verona beans from starbucks (which i really like) and usually do it in metal-filtered drip coffee machine. the only variance was that instead of drawing cold water from the tap, i had the water sitting at room temperature for couple hours (from night before) to brew my coffee. is this enough to make such difference?
i used to think unboiled water and plenty of medium ground coffee (right before brewing, stored in the bag i purchase them in) would be the most significant point-
or how could i make it better?
