The truth is that brewing coffee is a change that is physical perhaps not a chemical one.
But substance modifications remain a huge the main process—especially in terms of coffee that is roasting.
Brewing—A Physical Process
So, how does water turn to coffee if it isn’t via a chemical reaction? It all has to do with how water dissolves things. Them and starts carrying chemicals that are already in the coffee out when you put water-soluble coffee grounds into the pot, the water seeps into. In the long run, you’ll get a mixture of liquid particles and all sorts of the molecules that are delicious make up coffee, but new molecules aren’t created.
