If you’re like me, you didn’t know what a chemex was until you were introduced to independent coffee shops. Home brewing can be fun, but it’s not just for people who have espresso machines. Slow bars are such a great way to get delicious tasting coffee. Plus, you’re actually the one in control, kind of, versus an automatic machine. The equipment you’ll need: a chemex, chemex filter, ground coffee, a scale, and a kettle, a timer/stopwatch. We are measuring with grams and you’ll need to time the process. Make sure your chemex is clean. We use either dish soap or a cafiza tablet. Dry it before you begin.
- Measure your beans. Coffee for two: 30g of coffee beans
- If you don’t have a grinder at home, go to your local coffee shop and ask them to grind your whole bean coffee for a chemex. If they aren’t sure what that is, tell them a 7.5-8 grind will do (cough)Starbucks. Most independent coffee shops will know exactly what you’ll need. For reference, think a bit coarser than Kosher salt. How will you know if it’s too fine or coarse? The brew time should be between 3:00 – 4:00 minutes.
- Pre-wet your Chemex filter. Why? Gets rid of that paper taste and makes for a cleaner tasting cup of coffee.
- Once you pour your ground up coffee in the Chemex, we are going to bloom our coffee for a total of 30 seconds before adding the rest of the water. Just enough to soak the coffee.This effectively reduces the amount of CO2 left in the coffee seeds, allowing for a less acidic brew.
- We are going to use a 1/17 ratio for our pour. For clarity, when you’re pouring your water, you should end up with 510 grams of brewed coffee. So the 1/17 ratio is 510 grams. Some barista’s will get specific and go anywhere between 1/15 to 1/17. Best to try gradations until you’re satisfied with the ratio of your choosing.
- Pre-heat your cup, serve and above all, enjoy!
Overall, be sure the coffee is to your liking. If you like it a bit more light, dilute it (also the coffee you chose will determine this). Even though many people might not agree with me, don’t take it too seriously. Making coffee at home is fun. Pair your cup of Joe with a chocolate croissant. You’ll love. Stay tuned for the next home brewing post! Thank you, Johnathon for teaching me your coffee ways.
