Water temperaturefor a Chemex pour over: 205 F

Since some traditional coffee makers can only reach 160 F, manual methods of brewing immediately have the edge over an auto-drip pot. We use thisDeath Wish Stovetop Gooseneck Kettle. A gooseneck kettle gives you the most precise pour.

Can I use preground coffee in my Chemex?

If you buy preground coffee, the water will take far too long to pass through the filter and will over extract and become bitter. It is possible to brew a cup, but it will not produce coffee that properly represents the taste of the Chemex.

Brewing ratios for a Chemex: Strong

  • Water-to-coffee ratio for a Chemex, by weight: 12:1
  • Water-to-coffee ratio for a Chemex, by volume: 6 oz.:2.5 tbs.

One of the wonderful things about the Chemex is your ability to control the brew–this comes through best during the set-up process. It’s possible that the Chemex can make the strongest coffee of any non-pressurized coffee maker. So make sure to experiment with the ratio that best suits your taste.

The Importance of Blooming

This is thepart of the brewing process whereunwanted gasses from the coffee are released as the water hits the grinds, also called “blooming.” This is done by pouring just enough water to saturate the grinds in your filter and waiting ~30 seconds. You’ll notice your coffee “blooming”forming bubbles and expanding. This means that your coffee is fresh.

We love to start our mornings with a slow, aromatic pour over, which makes the Chemex one of our favorite ways to make coffee here at Bean Box. The classic carafe makes a clean cup of coffee with far less sediment than any other brewing method. And not only is the Chemex surprisingly easy to use, but it’s also easy on the eyes, making it the perfect coffee gift and addition to any kitchen.

What Is Pour Over Coffee

The pour over method involves pouring hot water through coffee grounds in a filter. The water drains through the coffee and filter into a carafe or mug. Pour over is also known as filter coffee or drip coffee, although these terms also include batch brewers.

What sets pour over apart is that it is made by hand-pouring the water over the coffee. So you may hear it called hand brewing or manual brewing.

The technique has been commonly used in Europe since the 1900s and elsewhere for much longer, but was rediscovered by the specialty coffee movement in recent years.

This article is going to go over step by step how to properly brew coffee using a Chemex coffee maker and give you tips and advice on the best way to make sure it comes out perfect each and every time. Ready? Lets get started.

What Is The Best Size Chemex

Quick Fix for Cold Brew: Iced Chemex

There are different sizes of Chemex makers to choose from out there. However, the right size that you should get depends on your needs and the budget.

A 6-cup or 8-cup sized Chemex coffee maker is most preferred because it can make a larger number of people and is also good for one person.


How to Grind Coffee for Chemex

Chemex coffee requires medium-sized ground. Hence, it will be best to use a Burr grinder. Burr grinder is preferred because you can set the grind size of your choice.

Once you have your burr grinder set, take freshly roasted coffee beans and put in them in the grinder.

Start the grinder and allow it to slice the coffee beans according to the set ground size.

What Kind of Coffee Grind for Chemex?

The ideal coffee size grind for Chemex coffee should be less chunky. Unlike the French press, Chemex coffee makers have thicker filters.

Very fine grinds will be over-extracted by the Chemex filter, which will result in a bitter coffee.

The Chemex flow rate will allow the extraction of the best flavor with a medium grind

What Size Grind for Chemex?

Chemex coffee makers have thicker filters compared to most traditional coffee makers. These filters are meant to regulate the rate at which coffee will flow.

This allows the extraction of most coffee components. Coarse grounds will not allow full extraction while fine grind will be over-extracted. The best ground size for Chemex coffee should be medium grind.

Which Pouring Technique Is Best

Avoid watching too many videos on technique when you first start to brew with the pour over method. It can quickly get overwhelming. Instead, start out simple. Be consistent in how your pour and learn how to use blooming, pulse pouring, and agitation to achieve even extraction. Many people pour in concentric circles, which helps the barista maintain a consistent flow of water.

You can work your way up to more detailed methods or break all the rules when youre more familiar with the basics.

  • The bloom

The bloom is the quick bubbling up of water that happens when you first pour. It is caused by the degassing of carbon dioxide that is built up in the roasting process. Light roasts and fresh coffee are likely to produce a big bloom because they usually contain more gases.

Carbon dioxide can prevent even extraction because it repels water, and the disturbed grounds can sit at different heights. So let the gases escape and improve your chances of a consistent extraction.

Gently pour twice the measure of coffee in water over the grounds. So, if you have a 15 g dose of coffee, pour 30 ml of water. Then wait 30 to 45 seconds until the bloom has ended and the grounds have settled.

  • Pulse pouring & continuous pouring

You can use pouring technique as another variable to consider when adapting your recipe. Different types of pours will have different effects on extraction and therefore have different impacts on your brew.

  • Agitation

How To Make Pour

When making pour-over coffee, the two biggest factors are:

  • Coffee bean quality
  • Purity of water
  • However, every detail matters. Getting a consistent grind coarseness, using proper measurements, and having the right temperature water will also improve how your cup of joe tastes.

    What youll need:

    Now, on to preparation. If you dig around enough, youll find varying recommendations on the ratio of coffee to water.

    Ive worked this recipe for a number of years and end up using 1g of coffee to 16ml of water.

    So for a pot of coffee that yields about 2 big cups , youd use 32g of coffee + ~500ml water.

    This assumes youre using a high-quality coffee bean and filtered water. Sometimes coffee is made unnecessarily strong to hide bean or water imperfections.

    I also tend to grind my coffee just a smidge finer than whats usually recommended , which seems to balance well with a little bit more water to make a beautiful cup of coffee.

    That said, dont be fooled. This is going to be a bold cup of coffee! I make adjustments when using a different bean or system, but this process has held up well for me for years .

    Pay Attention To The Spout While Brewing

    Due to the design of Chemex, if the air can not freely flow from the bottom and getting trapped in the chamber. It will build up some pressure, and the coffee may stop dripping down. Chemex designed the spout to avoid this, and the thick coffee filter with 3 layers is less likely to form a seal with the surface. But still, that happens from time to time.

    Tip: If it seals the pour spout, lift it slightly or use a chopstick to make sure the air can come out smoothly.

    How Much Ground Coffee Should You Use

    How to Use a Chemex to Make Coffee

    Now this is where all the ratios and scales typically come into play. If I were to follow the coffee experts advice, Id use 40-50 grams of coffee for 700 grams of water . But because I didnt want to pull out my kitchen scale every morning, what I really wanted to know was what that translated to in coffee scoops.

    So let me break it down for you. 40-50 grams of coffee = 4-5 coffee scoops. One coffee scoop = 2 tablespoons = 10 grams.

    Interestingly enough, all brewing examples I found online only showed brewing a Chemex half full I have no idea why. If you purchase the eight cup Chemex and would like to brew a full container, based on the math above youll need 70-80 grams of ground coffee or 7-8 coffee scoops for 40 ounces of water. Personally, I found this much too strong.

    Chemex themselves recommend one heaping tablespoon for 5 ounces of coffee, which means 8 heaping tablespoons or 4 heaping coffee scoops per 40 ounces of water. At the end of the day, I actually preferred 3 coffee scoops with a full kettle of water. Remember though, Im a coffee novice who doesnt like my coffee overly strong.

    Theres always talk of over extraction or under extraction when you start to alter coffee measurements, but really, its all about personal preference and taste. Each person is unique in our ability to taste, particularly when it comes to bitter compounds. So tinker around with ratios until you find what works for you.

    Recipe Notes And Tips For The Best Pour Over Coffee

    • I like to medium grind my coffee beans. If your coffee tastes too weak, you are probably grinding them too coarsely. You can make adjustments to the coffee grind size and see how a finer grind tastes.
    • If your coffee is too strong, add in a little extra hot water to your cup to dilute it.
    • Dont pour boiling water over the coffee grounds or they can scorch. Boil your kettle and let it cool for 30 seconds before using.
    • The total brew time is around 3 to 4 minutes.
    • You could also use a coffee dripper for individual cups of cofee instead of the large Chemex coffee makers. They are popular for their even extraction because of their flat bottom and some of the best tasting coffee.
    • The concept of pour over and electric drip coffee makers is the same but with pour over you have more control over the brewing process and each variable makes a notable difference in the type, taste and texture of the resulting coffee.

    Or How To Make An Iced Pour Over

    As the summer days and nights heat up, we love adapting our pour over ritual for a refreshing iced glass of coffee. On a recent trip up to Sea Ranch one of our favorite spots in California we spent some time playing around with some iced pour over recipes we like. One we’ve developed over time, and one made by Canyon assistant roaster Frank Valerio!

    While we made these recipes on Chemex, they’re really applicable for any type of pour over device. As a rule, grind a little finer for iced pour overs than you would for regular hot , and grind a little finer for other pourover devices than for the Chemex. Experimenting is the fun part, and if that sounds daunting, dont worry we explain exactly how you can experiment below 🙂 As well allude to later, we always stress to our friends, family and customers that you have the power to make adjustments and change how your cup!

    How to Make Chemex Coffee

    A good Chemex ratio to start with is 1:15, or one part coffee to 15 parts water. An 8-cup Chemex can make 40 ounces of coffee, so if youre brewing a full pot, youll need 2.7 ounces of coffee .

    Try this ratio and taste the results. If its not strong enough, increase the amount of coffee. If its too strong, decrease the amount of coffee. Simple enough, right?

    Why Use The Pour Over Method

    Pour over accentuates intricate flavors when compared to other brewing methods. This makes it a popular choice for single origin coffees, since it allows the flavors and aromas to shine.

    Good filter coffee is clean, clear, and consistent. This is because the water is allowed to extract coffee oils and fragrances in its own consistent time and at its own pressure. The filter then catches a lot of oils, leading to a clean cup.

    And because this is an infusion method, it is a little more efficient at extracting coffee solubles than immersion techniques such as the French press. Immersion methods cause the water to become saturated, whereas pour overs use a constant supply of fresh water.

    What Grind Size Is The Best For Chemex Brewing

    The right grind size for Chemex may vary from one person to the other, depending on their needs.

    While the filter does most of the work when brewing coffee with a Chemex, its vital to have the suitable grind size for Chemex to steer clear of over-extraction or under extraction.

    Brewing coffee with very fine grind will lead to over-extraction, while using a too coarse grind will lead to under-extraction.

    Over-extracted coffee wont be ideal, as it might be bitter. Under-extracted coffee will taste a bit sour and sharp as water hasnt had to absorb and break down enough sugars to neutralize the acids.
