As many others, we share the love for Coffee. After trying so many things. I have found that the Best way to make coffee is using French Press.
Also, you gotta make sure the beans used are of decent quality.
Although your idea sounds very appealing and that's why I'll be trying it; I do agree with the fact that re-brewing an already made coffee might not be the best approach.
Thanks a lot of sharing; regardless.
