Mining. In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network.
It matters because the actual coffee flavor is extracted from grind better at higher temperatures. I'm not a scientist but I trust those that have done the research and they say that the optimal temperature for hot water in a coffee pot is between 195-200 degrees or just a little under boiling.
Their especially machine was broken. Let them know. The actual temperature that coffee 'should be brewed', runs between 196.4-204.00 you don't want the water to be too hot or it will scorch the coffee. You also want the coffee to rest a bit before they pour if it is a brewed cup, called blooming. If the coffee is run through the hot water without blooming, you'll loose quite a bit of the flavor (which is why many buy coffee in coffee shops is because of taste, not just convenience). AND bad coffee, no matter where you get it, is just bad coffee. If it has been left sitting exposed to air, it will taste syrupy and harsh. If the beans are old, it will taste flat. If the roasting was not done properly, you'll have a nasty cup.
