Prepare the Perfect Pour Over

Pour over coffee

The humble pour over is my favorite coffee preparation method. What's not to like? It's so inexpensive as to be essentially free. There's no machine to break down. It's portable. You can't scald yourself with super-heated steam. It's relatively fast, and it's simple. Most importantly, it makes a great cup of coffee.

And though I love drinking a nice espresso, pulling a shot is a complicated affair on a very costly machine.

Despite this being a simple process, it is a coffee preparation technique. And that means that there are a lot of obsessed people creating ample options to make it very fussy. Some of these options will noticeably improve the taste coffee and are worth learning about.

So, how can you get the most of this most straightforward of brewing techniques?

The Set Up

All you need is a cone and a filter. Basic is fine. One of those plastic Melitta cones will work. If you want to you can splurge on a fancy porcelain cone. All that ever did for me though is make me paranoid about breaking it.

Any electric or stovetop kettle will work fine. But again, there's a way to spend more money if you're really dedicated: a goose-necked kettle with a smaller spout will give you more control.


You'll want a medium grind for pourover. Something like kosher salt or raw sugar is a good place to start. You can tweak the grind to fix problems with the coffee: if it's too thin, you'll want to grind finer. If it's too bitter, try a coarser grind.

Just Getting Warmed Up

Very fussy coffee people will tell you to set up the cone, cup and filter, then pour boiling water down the — coffee-less — cone and let it stand. This will heat everything up and perhaps remove any off flavors from the filter.

Try it out and see if you taste a difference. But be sure to toss the 'heating water' before you toss in the ground coffee and begin the brew.


Blooming is soaking the grind and then letting them sit for a while (say, 30 seconds). Talking about blooming will make you feel like A Serious Coffee Person and it seems like a esoteric ritual. But there is a good reason for it. grinds.

The rationale is to make sure all the air and CO2 escape from the coffee. If you pour the full cup right away, tiny gas bubbles between the grains and inside the cell walls will prevent contact between the soluble flavor components and the water. Letting the coffee bloom ensures everything is moist and so further water can dissolve all the coffee goodness.


Putting it all together, here's how you brew using the pour-over technique:

  1. (optional) Heat the filter, cone and cup with water. Wait a few minutes then toss the heating water
  2. Add the grounds. How much? For a 10 Oz cup (roughly 300ml), a good range will be 20-30 gr.
  3. Add enough water (just off the boil) to soak the grounds
  4. Wait 30 seconds or so
  5. Add the remaining water slowly. It should take between 2 and 4 minutes to brew


To find your absolute pour-over perfection, try these adjustments:

  • When adding the water, the darker your roast the shorter the time you want.
  • If the coffee is too thin and/or takes much less time than 2 minutes, try a finer grind or more coffee
  • If the coffee is too bitter, try a coarser grind

It's useful to keep in mind that all coffee brewing attempts to dissolve out the enjoyable flavor components while leaving the bitter, acrid ones for the compost. The tasty flavors will always come out first, so you need to tune the length of time the water stays in contact with the grounds to the darkness of the roast (darker roasts have more easily-dissolved harsh flavors) with the size of the grind.

That's it! Now you can enjoy a great coffee anywhere, anytime.

November's Roaster's Choice: Ethiopians

November. It's the month when you can no longer ignore the weather in the Pacific Northwest. The patchy rain of September and October become unrelenting and cold seeps into your bones. Another yearly reminder that we live in a land of drizzle and fog, swaddled in the clammy mist blanket thrown over us by the mountains.

The Yirgacheffe region of Ethiopia is not only on the other side of the world, but it is heading into a dry season. After 6 months of rains, the clouds are thinning and bringing warmer days and cooler nights. The rains have also ripened the coffee beans and as they dissipate in October trough December. It's time to harvest.

This month's Roaster's Picks come from Yirgacheffe and Kochere in the Sidama region of Ethiopia. They're grown at high altitude, which mutes the heat of the subtropical sun. The resulting coffee is silky smooth and tastes of lemons and berries — sweet, even without added sugar.

They're the perfect complement to our cold and contemplative days of autumn. Roasted to perfection, these are our most delicious varietals yet.

Cremazen Guide to Roasts

Cremazen's mad roaster

Roasting coffee is just cooking. You take an ingredient that's unpalatable — or downright inedible — and heat it to produce something delicious. And like cooking a delicious meal, roasting coffee is a surprisingly tricky process.

Learning just a little bit about it will help you understand how the coffee you enjoy was made. Armed with that knowledge you can select the best coffee for your palate.

Country of Origin

Each green bean picked has only potential flavor. Its actual flavor is gross. The spongy pale kernel of the coffee berry tastes almost nothing like the coffee it will become.

Each bean is a mixture of all the familiar food components: proteins, fats, carbohydrates. When you roast the beans, you begin a chain of chemical reactions among these constituents. The perfect roast brings all these reactions to a point where the flavors are balanced. That peak flavor in turn depends on the bean(s) and the unique growing conditions which produced them.

Taste is, well, a matter of taste. Some folks enjoy more bitterness. Some like sweeter, more complex flavors. On top of these preferences — and sometimes driving them — there's commerce: if you're a huge coffee producer, you need to make sure your product doesn't vary too much.

See, a Starbucks Pike Place Roast bought in Seattle needs to taste the same as one bought in Atlanta — or Bangkok. So you can't bring out the unique flavor of every bean; you need to find a repeatable recipe: a mix of origins, likely combined with a dark roast. Why a dark roast? We'll get to that.

So if you opt of easily-available coffee, you necessarily narrow the range of possible flavors you'll be drinking to those which work in a large-scale commercial operation.

Let's dive into the roasting process to see what other options there are.

The Roaster

Coffee roasters are huge cylinder of metal heated on the outside. The beans go in the hollow insides and the cylinder rotates. As it does, it heats the beans and because of the rotation, no one part of any bean gets scorched by lengthy contact with the cylinder, and no bean gets roasted any faster than any other.

The beans get dumped into the roaster and the beans are heated. Once the roaster decides the roast is done, the beans are dumped and cooled. Just how long and hot the roasting goes will determine the final flavor. You can thing of roasting as a timeline of flavor development; you chose the flavor profile by deciding when to stop.

Next, we'll take a look at that timeline in detail.


The first stage of roasting involves drying the beans. They contain a lot of water, so it takes a lot of time and heat to evaporate it all (well, most of it) out. Once most of the water is out, the beans will pop, just like popcorn. This is called 'first crack' and it marks the beginning of a time of rapid flavor changes in the coffee. You see, while there's a lot of water in the bean, you're basically just boiling them. Boiling as a cooking method is not known for it's flavor development. And as it is in the kitchen, so it goes in the roaster's drum. After the water is gone we can get into some very interesting flavors.

Between the Cracks

After first crack, the beans are light brown (called 'Cinnamon Roast') and dry on the outside. They proceed to darken until they eventually reach a dark brown color. At this point, there will be a 'second crack'.

At second crack, you've gotten the darkest of roasts and the beans are almost black, and oily on the outside. If you roast beyond second crack, you need to exercise care — you're moving inexorably to turning your fine beans from halfway across the world into very expensive charcoal.

The change in color is not the most interesting thing happening after first crack. Changes apparent to other senses are much more crucial: this is where the flavors are created.


Coffee beans have a certain amount of sugar in them. The roasting process first liberates them and then caramelizes them. Caramelization produces a more complex flavor, but one that's less sweet. So in general the darker the roast the less sweet it becomes, but the more caramel and complex, until finally all caramelized flavors are further transformed into decidedly not-sweet bitter flavors as the compounds begin to carbonize — literally turn ash.


The acidic taste in coffee is the dry, bright flavor. In general acidity will decrease as the roast progresses. Often coffees with a predominately acidic flavor will be described as fruity. The kind of fruit mentioned will give you an idea of the balance between the acidity and sweetness: a coffee with "notes of lemon" will be quite acidic and not very sweet. A coffee with plum and fig flavors will be both acidic and sweet.


Bitterness is one of the defining flavors in coffee. Bitterness generally increases as the coffee is roasted.


Ah, caffeine! Perhaps it'll surprise you to learn that caffeine content goes down the longer the coffee roasts. So that bitter, almost-burnt, brew that tastes as if it would wake a corpse actually has less caffeine than the more delicate-tasting lighter roast roasted from the same beans.


Take the roasting beyond second crack and you start to start to carbonize the beans. A little carbonization — like the black char on a steak — can be an interesting flavor. Too much of it and you start to feel like you're drinking charcoal.

One of the trickier aspects of roasting is that every bean goes the process at a different rate. Even with all the precautions taken in the design of the roasting machine to heat every bean evenly, beans vary in the moisture content, their size, and how close they end up to the heat source during roasting. Because of this, even very light roasts will contain a few carbonized beans. Diligent roasters (such as us, of course!) will take care to remove these since they're especially out of place in a lighter roast.


Putting this all together then, after first crack the coffee will progress from a bright 'clean', acidic flavor with substantial difference based on its origin to a less acidic, 'heavier', stronger and more bitter brew with fewer idiosyncrasies. This is described as a transition from the origin character to the roast character.

Post-Roasting Flavor Development

After the roast is done, flavor potential will continue to improve for a while, and then begin its long journey into staleness.

Next, the choice of [grinding][cremazen-grinding], brewing method will determine what aspects of the beans' flavor profile are emphasized.

Finally, the biggest change in the flavor of the coffee that actually passes your lips will be made after it brews: adding sugar, cream (or creamer), flavors, etc...

As we mentioned above, the darker roasts are more bitter and less sweet. Such roasts have a bold flavor which can stand up through these very strong companions. This is why large chains that sell lots of very sweet coffee drinks prefer darker roasts: you'll still be able to taste a coffee-like flavor even with 600 calories worth of sugar and milkfat.

Roasting at Cremazen

At Cremazen, we believe in customizing the roast to the bean in our single-origin coffees. Our aim is to bring out the best possible flavor from each batch so you can taste the terroir — the unique flavor that a particular spot on the earth infused into its plants. This means some trade-offs: the supply of the green beans is limited and seasonal. So our Burundi may come and go. The flavor of each single-origin is unique.

Our only blend — the [Festival Blend][festival-blend] — maintains consistency over time by using a mix of reliably-supplied single origin beans. Being more darkly roasted, it'll stand up better to cream and sugar, if you prefer your coffee that way.


  1. The more you add to your coffee — cream, sugar, flavor pumps — the darker a roast and the more you should chose blended rather than single-origin.
  2. If you take your coffee black, try single-origin, lighter roasts. If you haven't done so, you might discover an entirely different kind of coffee than you're used to.
  3. Pair your coffee with a suitable brewing method: darker roasts benefit from coarser grinds and longer brewing methods (e.g. French Press), lighter roasts benefit from finer grinds shorter brewing times (espresso and pour over)

Great coffee depends upon many factors, the first being the beans themselves.  We at Cremazen offer high-quality beans selected from the best growing regions.  We roast them with care.

But it's still possible to make a substandard cup with them. And that would be a shame.

So how can you make sure to get the most out of these special beans?
