Improving Clarity

John says...

When it comes to coffee and espresso, clarity is important. We've had the same filtration system since we opened, and it's time to improve it. I've been wanting to upgrade our water filtration for a while now. I've ordered two Everpure Claris filter systems.

It is an adjustable filtration media that includes a five stage process for eliminating scale, dirt and fine particulates, odors/off flavors. I believe that for the money and simplicity it's the best system out there.



The Claris uses a Hydrogen (H+) ion exchange rather than a Sodium (Na+)exchange.

"The Claris resin is loaded with hydrogen (H+). The hydrogen ions dissolve the carbonates (CO32- and HCO32-) , and the resin then removes the calcium and magnesium ions (Ca2+ and Mg2+). This process also lowers the pH."


I will soon find out how it tastes.

Good Methodology = Good Espresso

John says...


Testing SO Ethiopia Suke Quto espresso.


I love testing new espresso. I also love testing whether or not something will work as a Single Origin espresso or as a component for espresso. Today I had some extra Guji Suke Quto from last night's tasting class. Now I've used this as a component of an espresso, but I haven't really tried it as a Single Origin. Golden opportunity. This allowed me the opportunity to test without roasting an entire new batch, and if the roast level I used for the coffee will work or not.

So the question I am asking is, "Does it work?"

I'm pretty systematic about my testing. I know what range of grind to target, so I pick a midpoint and start from there. I keep the Synesso at the temperature set for the current espresso (199 F). No need to change until after I taste... but that's still a bit away.

One step at a time.

I tare the portafilter and grind. How much? I guess and see where I'm at. 17g. Ok. Tamp. And as Captain Picard says, "Engage!"

First I'm just watching for flow. It's too fast.

I adjust the grind a little finer. I dose the same weight. Looks a little better...
I'll give it a taste. Sip. Mild citrus, hint of nut. ... good, but it seems like it's lacking something. It's not a one dimensional coffee. I know there's more there. I just have to find it.

Let's approach 18 g.

Puck looks pretty good.

I always pull a second one so I know if it was a fluke or not, and it looks the same.

Taste.

Bingo!

First sip - Candied ginger, sweet citrus and jasmine. Second sip - warm spice, a touch of bergamot, honey sweetness. Finish - dark honey to maple sweetness, restrained citrus, hint of spice.

Does it work?

I'd say, "Yes." But it's not that simple.

All coffees aren't this easy. Even when they work. Sometimes I go through ten or twelve shots and I'm about to give up, then everything comes together. And then it fades. The real question isn't "Does it work?" The real question is, "Can I do that again?"

Well, can I?

Grind. Dose. Distribute. Tamp.

Taste.

And the answer is

.
.

Yes!

The importance of cup shape and design

John Says...

I have been thinking about demitasse cup shape lately. You see, most cups are about the same, whether it's the nova point moka brown ones or the IPO white cups and even the tulip shaped cups really fall into the same category. But I have one demitasse in my collection, a small brown cup from Germany, that, hands down, is the best demitasse for espresso I have used.

One of the key questions I have asked myself when looking to get the best out of a cup of coffee or espresso is: How do we capture and transmit the essential aromatics? As many know, it's the aromatics that are the most important factor in determining the flavor of the coffee. All things being equal, the better the presentation of the aromatics for the particular beverage, the more dynamic and richer flavor experience for the consumer.



That being said, the typical demitasse has an opening diameter of 2 1/16" to 2 1/4" and a height of about 1 7/8 to 2". This particular demitasse has in opening diameter of 2 1/2" and a height of 1 3/8". This wider opening, shorter and less tapered design creates more surface area for the crema and allows your nose to hit closer to the center of the cup rather than the edge. This essentially surrounds your nose with aromatics. Also, the way the flavors present themselves in the cup seem somehow more pronounced, beyond what the aromatics should provide. My theory is that the dispersion and layering of the espresso is different enough that it results in enough separation for greater clarity without losing balance.





While it's certainly not enough for a scientific trial, I've had about thirty shots of espresso to compare (60 total) on roughly 12 different espresso - both blends and SO, and I've pulled about eight shots for our best customer who gets espresso daily. The first time I made an espresso for him in this demitasse, I didn't say anything, and all he could say was "Wow!" to the same espresso he had earlier in the day, but in our normal demitasse. Every time we each remark at how good it tastes.

When it comes to the siphon, cup shape certainly matters to us. Now the best shape when it comes to the aromatics of the coffee, is actually a Champagne flute.. but at about 4-5 oz, expensive, and a general pain in the ass to keep spotless... it's not the most practical delivery system.

We therefore specifically use tapered or tulip shaped Japanese bone china, and a few German as well (for some reason, the handles on many of the German cups are oddly small). The cups are usually 7-8oz, but sometimes five. Larger doesn't make any sense at all. It's the same reason why you don't serve wine in a one liter boot or hefty stein. And the shape maintains the best aromatics out of the useable drinking vessels. A smaller cup with a smaller diameter also works well too. The nose isn't as pronounced in the beginning, but it will maintain a balanced clarity throughout.


One of the most important aspects of choosing the right cup, is raising the level of the coffee experience for the customer. To make coffee by the cup, and serve it in a paper cup is insane (and not the good kind!) . Or to serve it in the same ceramic you use for everything else really doesn't convey the specialty of what the customer is about to consume. How can we expect a customer to understand what they are receiving if we treat it the same as every other cup. And if EVERY cup is special, then treat every cup that way. Find the best way to prepare, and the best vessel to serve in, and in doing so you honor the coffee, the customer, and your business.

I recommend...

John Says...

I highly recommend the Brazil Fazenda Esperanca. I have cupped this coffee both as a siphon brewed coffee and using a press, and it is a truly remarkable coffee worthy of it's first place finish in the 2006 Brazil Cup of Excellence, where it received a score of 94.43.



As a siphon coffee, there is an amazing clarity of citrus and honey sweetness. As the cup cools the citrus notes become more defined into snippets of tangerine, orange blossoms, and a lingering finish will tempt your palate for a second and third cup.

As a press coffee, there is a great depth of flavor. There amazing clarity subsides just a bit and is replaced by an intertwined complexity of flavor and depth. The caramel notes surround and support the citrus flavors with hints of spice. While the finish is not as long and citrus sweet and the siphon brewed, the satisfying flavor is one that will dance on your tastebuds.

This coffee has placed in the top six finalists since its inclusion in the Cup of Excellence competition.

Phenomenal.

Evaluating Espresso: Timing vs. Flow

John says...

Most of us are familiar with the "Golden Rule" when making espresso -- 3/4 to 1 ounce of espresso in 25-30 seconds, or roughly double that volume for a double shot. When pulling a shot of espresso, how concerned should you be with the timing? How concerned should you be with the flow?

Obviously a combination of both must factor into play, but without going into the myriad permutations you can have of this or that, you come down to the main questions..

Too fast or too slow, which is worse?

There is always an ideal range you want to fall in, but between the two, you would rather have a thirty-five second or greater pour than a sub twenty second pour.

This is because espresso, in layman's terms, is about extracting the optimum amount of flavorful oils from the grounds. But how do we determine if this has happened?

I use timing as a 'rule of thumb' guide and then primarily watch flow and inspect the portafilter to see if it is clean. If the portafilter is clean, and the timing fell in the optimal range, we can assume that the oils were extracted perfectly, and made it into the demitasse. If there are dark oil stains on the inside of the portafilter, this is usually an indication of overextraction... or poor distribution, but that's a topic for another time.

If we underextract, as many places do, and get that eleven second pour, there are virtually no flavorful oils being extracted, and unflavorful piss-like espresso will usually be the result. I can opt for intense at times, but unflavorful, weak espresso is a far worse crime.




How important is the flow?


Flow is important because it gives one a good indication of the color and density of the crema. While the existence of crema is not the end all be all of espresso, it is most certainly one of the most important factors. Crema is important because of all of the body, texture, flavor, and aroma it gives to the espresso.

It's never a simple process, but evaluating espresso by taste is the ultimate way to judge, so whether there are dark oil stains in the portafilter or it was a thirty-eight second pour, we have to use our palate as the ultimate judge. Of course, in my opinion, a great tasting espresso with indicators that it is somehow flawed can only mean there is more improvement ahead.

While this is not intended to be anywhere near a deep exploration of the subject, I hope it will at least get your brain churning.

Rapid Brewing with the Finca El Injerto

John says...

Today I tested a fresh (roasted 10p last night) batch of Guatemala Finca El injerto on the siphon.

Grind 3 notches from 'espresso' on Mazzer Mini.
Brew time 20 seconds.
Rapid stir.

The taste? sweet nut, floral, light caramel and a bit of cocoa.

Wow.

Mountain Mambo Espresso

John says...

While the main components of this blend remain the same, I often alter percentages and experiment with different pre and post blending methods as well as different roast levels. This way, I can discover flavors I may have missed or lost with some other combination.

This current batch as espresso is peach, mango, light bittersweet almond and hints of honey and chocolate. In cappuccino, it tastes like a peach/apricot creamsicle up front with the almond taking on a lighter, but sweeter role. Not recommended for drinks above 12 ounces.

This espresso is not for the choco choco dark caramel and wood crowd.
But for those looking for a bright, lively, multi-dimensional espresso--this is it.

Kenya AA - Nyeri Kiamaina Tasting Notes

John Says...

Today I tested a batch of the new Kenya AA Nyeri Kiamaina.

This batch was roasted to a City Roast at 9:00 AM this morning.
Testing was done at 6:00 PM.

I brewed several batches in the Siphon brewer, and even on day one, the flavors are coming through. Peach and maybe a hint of floral apricot in the aroma. Peach and lemon up front, with the peach dominating as the cup cools. A sweet and balanced finish of peach and honey.

I found this coffee to be exceptionally clean, even by my radical standards. It's truly a magnificent coffee and creates a cup you will long remember.

Pursuing Perfection with Panama: Siphon Techniques

John says...

Today I am testing the Panama Carmen Estate
This coffee was roasted 9 days ago at a City roast.


Test 1:
Grind at 4 notches above espresso grind on Mazzer Mini.
9 grams coffee, 5 ounces water.
Coffee in. Water Boil and up. Stir to saturate grounds and distribute heat evenly.
Brew 40 seconds.
Heat off.
Stir Rapidly.
Cool and drink.

Test 2:
Grind at 2 notches above espresso grind on Mazzer Mini.
9 grams coffee, 5 ounces water.
Coffee in. Water Boil and up. Stir to saturate grounds and distribute heat evenly.
Brew 40 seconds.
Heat off.
Stir Rapidly.
Cool and drink.

Results.

This coffee being roasted a hair lighter, my suspicions were found to be true.

Test 1 was a balanced peach/vanilla with very subtle, yet sweet citrus notes.
As the cup progressed the citrus became more defined, but surrounded by an essence of vanilla.

Test 2 had more separation up front in the cup. Strong Peach notes with a bright citrus aftertaste. As the cup cooled, the vanilla came out and began to mingle with the peach.

The finish in Test 1 was sweet light citrus.
The finish in Test 2 was a bright citrus with the slightest hint of vanilla.

What does this tell me?

It's obvious that even with a small adjustment, there is a direct correlation between roast level and grind. And it is the balancing of the sweet, citrus, and more rounded, or even spice notes that are where the technique comes into play.

Tomorrow I will use the same method on the Papua New Guinea Peaberry, which has a lot of spice and tea notes.

more to come...

Revisiting Rwanda: Siphon Techniques

John says...

Today I am testing the Rwanda Kinunu.
This coffee was roasted 6 days ago at a City+ roast.


Test 1:
Grind at 4 notches above espresso grind on Mazzer Mini.
9 grams coffee, 5 ounces water.
Coffee in. Water Boil and up. Stir to saturate grounds and distribute heat evenly.
Brew 40 seconds.
Heat off.
Stir Rapidly.
Cool and drink.

Test 2:
Grind at 2 notches above espresso grind on Mazzer Mini.
9 grams coffee, 5 ounces water.
Coffee in. Water Boil and up. Stir to saturate grounds and distribute heat evenly.
Brew 40 seconds.
Heat off.
Stir Rapidly.
Cool and drink.

Results.

Both the aromatics and coffee on Test 1 were slightly sweeter. A little more fruit and citrus note.

In the middle of the cup, Test 2 tasted more complex. It was a collection of flavors coming together vs. a layered effect of lighter and brighter vs. wood and nut/spice.

The finish in Test 1 was superior.

Preliminary Conclusion:
Do same test on Panama Carmen Estate and see if the results are similar, or is the method entirely coffee dependant?

Stay tuned...

Espresso: IN YOUR FACE

John says...

As I mentioned in a previous post, I've been experimenting with some radical blends.
I have finished the degassing on a blend of eighty percent Kenya Ruiru Peaberry and tw Guatemala Finca El Injerto SHB. I roasted the Kenya at two different roast levels. 25 percent was roasted at a very light city roast, and the rest of the Kenyan and the Guatemala were roasted at a City + roast... just between first and second crack.

Pulled as a ristretto, 16.5 g @ 198 degrees, BRIGHT orange citrus, almond, hint of dark chocolate in the finish.

In cappuccino, lightly sweet orange and almond.
