The everyday coffee people drink tastes absolutely awful. The issue is that when naturally delicious coffee beans are cooked quickly with a lot of heat, they’re stripped of all their natural sugars and unique flavors. Here’s an in-depth sciency coffee brewing article if you’re interested in reading further. Do yourself a favor and avoid pour-overs, presses, and expensive cappuccino machines, and just get yourself a large mason jar and a filter.



Starbucks sources their coffee beans from all over. The way they get a consistent flavor is by over-roasting the beans. When over-roasted, the beans become bitter and similar tasting to a spent cigarette. This is why people add sugar (which replaces the removed natural sugars) and cream (to cut the bitterness).

Starbucks also benefits from over-roasting by having a pronounced coffee flavor in their most popular dessert drinks (e.g. frappuccinos).


Descriptive Instructions

Grab yourself a 64 oz. mason jar ($5) and a filter ($15-ish Amazon link). Mix a ratio of roughly 5:8 coffee to water. If you grab the filter from the link, just fill coffee to the top and the rest of the mason jar with water. Make sure you seal the jar tight and let it sit overnight in the fridge.

It helps quite a bit if you rock it back in forth in your hands every few hours, but this isn’t necessary. You’ll notice that it may need more water after doing this, so add additional water if it looks low. Be careful not to drop the heavy jar as it’ll be slippery from condensation.

In the morning, take the jar and pull out the filter. Not having the filter is a significantly more painful process and not worth the $15 saved. Make sure you wash the filter in the dishwasher’s top rack after use as this will significantly affect the flavor of your brews after repeated use.

When ready, add a shot glass worth of cold brew to a cup of hot water or cup of ice water.



This is a tricky subject. Since you’re using a lot of coffee, start with whatever you can purchase in bulk. When you get your process dialed in, aim for single-origin and avoid “blends.”
