The difference between Premium Coffee and regular coffee can be subtle or obvious, depending on the brands. The former of the two is typically used by connoisseurs whom have a love for coffee that the “Regular Joe” does not.
Premium beans that make the high-end coffees have been perfected and cross-bred over the years to the point where the expensive price tag is more than worth it for those who take their coffee seriously.
These coffees are typically not found in supermarkets, but rather ordered online from the makers and suppliers themselves. There are gourmet shops in the bigger cities, and the drinkers of these coffees will know where they are.
Some of these shops even double as “coffee bars” in the way that some cigar shops double as “cigar bars”. Where like-minded “connoisseurs of the bean” go to sip and talk shop.
