As explained earlier double brew coffee means double strength coffee mostly and there are mainly two methods to prepare a double brew coffee, either brew it again in the coffee machine or use twice the coffee ground, the first method is far more preferred for the following reasons. Simply running the already brewed coffee again through the coffee machine not only spoils the flavor, it can also make the coffee rather stale and unpleasant so its always better to take the longer but more rewarding route.
The longer coffee brews, the more bitter it gets, as the heat brings out the tannins in the coffee so don’t try to make double brewed coffee by cooking coffee grounds on the stove for an extended period of time. You may try by taking twice as many grounds as usual or use spices like cardamom which is ideal for iced coffee. Also as double brew or double strength coffee contains higher caffeine it could also result in a shock to your body system or higher body metabolism so it doesn’t hurt to ask the caffeine content the next time you are offered a cuppa.
