01

There are many automatic drip coffee machines on the market that offer a variety of sizes and add-ons, so you’ll want to follow the instructions that come with your specific machine. But here are a few tips to make it a great cup

02

Start with a 15:1 brew ratio of water to coffee and adjust to your personal preference. 

03

If your machine requires a filter, put your filter in place and wet it with hot water before putting your freshly ground coffee in (dispose of the waste water prior to brewing). This removes any paper flavor that passes on to your cup of coffee.

04

Grind your coffee beans just before brewing to get the most flavor and freshness out of your coffee.

Equipment

scale

hot water

whole bean coffee

standard 34 oz french press

Instructions

01

Weigh out and grind 54 grams of coffee on a coarse grind. Your ground coffee should look similar to coarse sea salt.

02

Pour a small amount of hot water in the french press to preheat the vessel, then pour out.

03

Place the french press on the scale; Place freshly ground coffee in the french press; evenly distributed at the bottom and then set the scale to zero.

04

Grab your timer and start it just when you begin to pour the water. Pour enough hot water over the grounds to evenly saturate them (about 30 grams); wait 30-40 seconds for the coffee grounds to ‘bloom’ (the fresh coffee releases CO2 and gets all bubbly).

05

Pour the remaining water in the vessel until the scale reads 920 grams. Place the french press top on the vessel.

06

When the timer reaches 4 minutes press the plunger down all the way.

07

Immediately pour your coffee, sip and enjoy!

vessel to brew coffee in (such as the Hario Glass Range Coffee Server)

V60 Hario filter

Instructions

01

Place V60 cone on top of the coffee mug, open up and place the V60 filter in the cone, ensuring it sits sung all the way at the bottom of the cone. Wet the filter with hot water, let drain, then move the V60 cone to the serving vessel. 

02

Bring 360 g of water to a boil, then take it off the heat.

03

Weigh out 26 grams of coffee; grind coffee on a medium grind (should look similar to kosher salt).

04

Place ground coffee evenly in the filter, then move the entire set onto a scale and set the scale to zero.

05

Start the timer! Slowly pour 60 grams of water over the coffee, saturating all of it. Wait 30 seconds for the coffee to bloom (the fresh coffee releases CO2, gets all bubbly and rises!)

06

Slowly pour 100 grams of water in an even spiral starting from the outside in. (TIP: Pour water on the coffee, avoiding the sides of the filter. Aim for the dark spots, rather than the light spots to get an even extraction). Wait 10-15 seconds.

07

Repeat step 7 until you reach 360 grams on the scale.

08

Let the rest of the water drain into the vessel, then remove the cone.

09

Pour, sip, and enjoy!

Chemex Filter

Whole Bean Coffee

Instructions

01

Open the Chemex filter into a cone shape, place in Chemex so that the triple-folded part is facing the pour spout.

02

Wet the filter with hot water, then pour out the water through the spout.

03

Bring 700 grams of water to a boil in a kettle, then set aside.

04

Weigh out 50 grams of coffee and grind at medium coarse (like sea salt); Pour grounds into the filter. Give the vessel a little shake to make the grounds lay evenly and flat at the bottom of the filter.

05

Set Chemex on scale and set the scale to zero

06

Start the timer when you begin to pour. Slowly pour about 50 grams of hot water from the kettle, evenly saturating the coffee. Stir the coffee with a spoon, making sure there are no dry clumps. Wait 50 seconds for the coffee to bloom (the fresh coffee releases CO2, gets all bubbly and rises!).

07

Slowly pour in a gentle spiral going from the inside out (careful not to touch the filter, just the coffee) until you reach 450 g of water. Wait about 30 seconds.

08

Slowly pour the rest of the hot water (reaching 700 grams on the scale) using the same spiral motion.

09

Let the water drain. The volume of coffee should reach the bubble in the Chemex glass at 4 about minutes (give or take).

10

Remove filter. Pour, sip and enjoy!

RetroRocket Tips

    Start with clean equipment - regularly clean your brewing device so there is no leftover coffee grounds or oils as this affects the flavor of your next cup of coffee.

    Get a scale - it will help you recreate that great cup of coffee over and over again.

    Purchase whole coffee beans that have been roasted no more than 3 weeks before purchase date.

    Grind coffee beans just before you brew to get the most flavor out of your coffee.

    Store coffee beans in an airtight container, room temperature

A Bit About Brewing

Coffee is a delicate beverage. Everything, from where it comes from, how it is roasted to how it is brewed affects and changes the flavor. A few things to note when brewing coffee: Follow a recipe; Just like baking bread, you’ll want to measure out how much of what ingredients you use so you can refine and repeat. Things that will be a part of your recipe list include type of coffee, water, the brew ratio, grind size, and brew method.

There are endless ways to customize your coffee to make it just the way you like it. In the end, Ground Beans + Water = Cup O’ Joe. So don’t stress! Have fun experimenting and creating recipes that you like best.

Brew Ratio

The brew ratio is the ratio of water to coffee when making coffee. A good median brew ratio is 17 gram of water to 1 gram of coffee. This is a general guide and you can adjust this ratio based on the type of coffee you are using, your brew method and, of course, your personal preference. To give you an idea of how ratios affect flavor, a 10:1 ratio would be thick cowboy coffee, whereas a 20:1 ration would be extremely weak. Try to shoot in between that and find what recipe you like best. The way you brew your coffee (your brew method) will also determine your brew ratio.

To calculate brew ratio: Say you are going to do a 18:1 ratio (18 grams of water to 1 gram of coffee). figure out how much coffee you are brewing first (how much water will fill your vessel); For example: an average size french press is 34 oz; 34 oz = 964 g; Divide 964 by 18 (which = 54 g); So you’ll need 964 g of water and 54 g of coffee.

Feeling Fine
Grind Size

The finer or coarser your coffee is ground has a big impact on the quality of your cup of coffee. If your grind is finer (like fine sand), the water will pass more slowly through the coffee grounds, taking a longer time to finish brewing. If you grind your coffee coarse (like extra coarse peppercorns), the water will pass through fast, speeding up the process. We also provide recommendations for grind size in our Brew Methods section to help you.

If your coffee is tasting bland and bitter, it may be over-extracted (the grind size is too fine); if your coffee is sour or salty it may be under-extracted (the grind size is too coarse). Adjust one variable at a time. Start with the grind size and try to brew your coffee within the time recommended for that method. If after you change the grind size and it is still not brewing at the recommended time, you may then want to adjust the brew ratio—add a little more coffee if it is done too soon, or a little less if it has gone too long.
