I'm no coffee snob, but I love coffee of all sorts and styles. I drink far too much of it, per everyone that knows me well... like to the point that it may be a problem some day.
My personal favorite is home made cold brew that has sat for 12 hours in my fridge in a half gallon mason jar.
After it has brewed, I pour it through a paper filter into a second jar and it's pure heaven. No sweetener or cream needed, just smooth black cold brew coffee. The beans used make a big difference in the final flavor, as you can really taste their full flavor this way. I usually just steal free coffee from work, but they have a Kona blend and a house Starbucks blend that works well enough. Not the best, but good enough to get me going in the morning.
