Coffee Brewing Workshops

I decided to open my coffee brewing workshops held within Ankara Coffee Community to enthusiasts from Ankara and İstanbul. 

The workshops include brewing with V60, Chemex, Aeropress, Kalita Wave and some other equipment. It is interactive and attendants can find the opportunity to brew their own coffee to compare the results. We also share intensive technical information via slides. The groups can be between 4 and 8 people.

It lasts around 3,5 hours and the fee is set not to exceed the price of a 500 grams package of specialty coffee.

If you can not get satisfactory results from your brewing equipment at home or you are a barista but not good at new generation brewing methods, or else you are planning to open a coffee shop and need consultancy, or you are just planning to buy new generation equipment, you can join.

Acaia Kahve Tartısı - Kesinlik, Hız, İşlevsellik ve Bağlanabilirliğin Kahve Demlemedeki Önemi

Başlığın firmanın kendi reklam yazısı gibi tonladığının farkındayım; ama Acaia kullanmaya başladıktan sonra kahve demleme ile ilgili yaşadığım devrimi -evimde kendime ve küçük atölyelerde bazı arkadaşlarıma demlediğim sırada- tam anlamıyla anlatabilmek için olabildiğince kısa bir başlıkta tanımlayıcı bir kaç kelime kullanmam lazımdı ve sonuç bu oldu. 

Özellikle V60 ile yaklaşık 3 yıldır -ve bir çok diğer metotla yaklaşık bir yıldır- kahve demleyen biri olarak, kahve demlemedeki en önemli noktanın tutarlılık olduğunu düşünüyorum. Her ne kadar bu sadece kahvecilerde ve nitelikli kahve mekanlarında bir zorunluluk gibi görünse de, evde aynı çekirdekle ve ekipmanla hep aynı kahveyi demleyebilmek de bence oldukça önemli. Tartı çok açık bir şekilde bu standardizasyon zincirinin en önemli parçalarından. 0.1 gram hassasiyet, öğüteceğiniz kahveyi tam olarak tartabilmek ve öğütücünüze gömülü tartı yoksa demleyeceğiniz kahve miktarını tam olarak görmek için, şüphesiz tutarlı kahve demlemek adına size çok yardımcı olabilecek bir özellik. Zaman zaman göz ardı edilebilen başka bir özellik ise tartının cevap süresi. Basit ve yavaş ölçüm yapan 1 gram hassasiyetli mutfak tartıları ile %5 hata yapmak çok kolay ve bu tartılarla az miktardaki kahveyi tam tartabilmek için yeniden yeniden uğraşmak oldukça vakit kaybettirici olabiliyor. 

Dürüst olmak gerekirse, kahveye özel olarak tasarlanmış hemen hemen her tartı hassasiyet ve kesinlik konusunda yeterli performans göstermekte. Hız konusuna geldiğimizde ise sanırım Acaia'nın kahve dünyasındaki yerini tarif etmek için araba dünyasının Bugatti Veyron'unu kullanabiliriz. 

Yine de, bu hız meselesinin kesinlikle Acaia'nın kahve tartıları arasındaki ayrıcalıklı yerini tek başına açıklayabilecek bir özellik olduğunu düşünmüyorum. Bence Acaia'yı farklı yapan, tartının Bluetooth üzerinden kontrol edilebiliyor ve arayüzünün akıllı cihazlardaki uygulamalarla takip edilebiliyor olması. Zihninizde canlanan o soruyu duyuyor gibiyim: "Kim neden bir kahve tartısını i-Phone'una veya i-PAD'ine bağlama ihtiyacı duysun ki?" Açıkçası ilk bakışta benim de aklıma gelmişti bu soru; ama yine de yakın zaman önce bir tane Acaia edinme kararı aldım.

Benim için hikayenin ilginç kısmı tam da bu karardan sonra başladı. "Brew Master" adında bir uygulama -standart Acaia uygulamasına ek başka bir uygulama- ile daha çok vakit geçirdikçe su akış hızının da kontrol edilmesinin mümkün olduğunu öğrendim. Kahve demleme reçeteleri su dökme anlarını belirliyor olsalar bile ne zaman durulması gerektiği ile ilgili bir bilgi vermezler. Bunun dışında, başladığınız ve bitirdiğiniz anları biliyor olsanız bile -ki bu size ortalama bir akış hızı verir- tartınızı gerçek zamanlı olarak inceleyerek döküşünüzün sabit hızda mı dalgalanmalarla mı olduğu hakkında bir bilgi edinmeniz çok zordur. Bu bilgiyi edinmek sadece demlemenin ardından yapılabilecek bir inceleme ile mümkündür. "Brew Master" uygulaması bunu yapmanız için size inceleyebileceğiniz bir grafik sunmakta. Akış hızını ve tutarlılığı grafiğin eğimlerinden ve genel yapısından inceleyebiliyorsunuz. (Lütfen benim fotoğrafımdaki ortalama akış hızı verisini dikkate almayınız; çünkü benim demlemelerimde karıştırma ve "tapping" olduğu için tartının ölçtüğü değerlerde ani iniş ve çıkışlar olmakta. Ama sadece eğimleri inceleyerek kendi akış hızım hakkında bilgi edinebiliyorum.) Tecrübelerim sonucu söyleyebilirim ki, bütün diğer değişkenleri sabit tutarak, sadece akış hızı ile oynadığımda çok farklı kahveler üretebilmekteyim. Sonuç olarak, hızlı cevap veren ve Bluetooth üzerinden incelenebilen Acaia ile döküş hızını inceleyebilir ve sevdiğiniz kahve için en uygun hıza kendiniz karar verebilirsiniz. Buna ek olarak, bu uygulama ile demlemeleriniz için sıcaklık ve öğütme kalınlığı gibi bütün değişkenleri içerecek şekilde notlar alabilir ve diğer kullanıcılarla bu bilgileri paylaşabileceğiniz bir sosyal ağa katılabilirsiniz.

Bluetooth bağlantısının benim için iki avantajı daha var: Tartı zaman zaman yeni sürüm yazılımlarla internet üzerinden güncellenebilmekte. Minimal tasarımlı tartının üzerindeki iki tuşun fonksiyonlarına kadar daha kullanışlı değişiklikler gelebiliyor yeni sürümlerle. Bu özellik bence oldukça faydalı; çünkü zaman geçtikçe kullanıcıların oldukça farklı ihtiyaçları ortaya çıkabilmekte. İtiraf etmeliyim ki diğer avantaj biraz bana özel; ama atölye çalışmalarımda daha fazla insana ulaşmak için demleme oranlarımı ve döküş hızımı/sürelerimi bir i-PAD ile katılımcılara gösterebiliyor olmak müthiş faydalı bir özellik.

Bitirmeden Acaia Pearl'in bir de siyah modeli olduğunu (benim fotoğraflarımdaki Acaia Pearl White) ve firmanın en son tasarımının espresso tablalarına da sığacak küçüklükte ve sızdırmaz özellikteki Acaia Lunar olduğunu belirtmek isterim.

Acaia Scale - The Importance of Precision, Speed, Functionality and Connectivity in Coffee Brewing

I agree, the title looks like the brand's own advertisement but in order to give details about the revolution in my coffee brewing experience after Acaia -which is at home for myself and at some workshops for my friends and followers- I need to choose some descriptive words in a short title and this is the result.

As someone brewing coffee especially with V60 for almost 3 years now - and many other methods for about a year - I think the most important part of coffee brewing is the consistency. Even this looks like a "must" only for coffee shops and specialty coffee centers, it is essential, also as an amateur at home, to get the same cup every time you deal with the same beans and the brewing equipment. Scale is obviously one of the most important parts of this standardization chain. Sensitivity of a 0.1 grams in weighing your coffee amount to be brewed (and to be ground if your grinder has not a scale on itself), is a feature that can evidently help you to create consistent cups of coffee. One other feature, which can easily be ignored, is the response time of the scale. With a simple slow responding kitchen-scale you can easily make %5 mistakes during pourings and lose time while trying to weigh the beans and ground particles of amounts of 1 gram.

Frankly, almost every coffee specified scale on the market can satisfy a sufficient sensitivity level and accuracy. For the speed, although most of these scales can supply a satisfactory result, Acaia seems to be the Bugatti Veyron of the brewing world. 

However, this speed issue can not be the only key feature behind Acaia's distinguished place in coffee scales. I think, it is its connectivity features based on Bluetooth what makes Acaia really different. This way you can easily connect to your scale with an application on your smart phone or tablet. I can hear the question that arises in your mind: "Who may need to connect a coffee scale to a smart device?". At first sight, I thought the same but I decided to get one and try to use all its features. 

Then there came the interesting part for me. As I spent time with an application called "Brew Master", which is an additional one to the basic Acaia Scale application, I learned that there is a way to control the flow rate too. Even if the recipes for coffee brewing methods mention the instants for starting to pour, they generally do not care when to stop pouring - which can give you an average flow rate actually. Besides even you know when to start and stop, you can not know whether you pour consistently or not by just watching your scale's display in real time. This can only be observed as a post-processing activity which may be achieved by a recorded data. The Brew Master applications let you do this and it creates a whole record for your brewing, which you can see the slopes and curves created from your pouring rate. (Please do not care about my average flow rate in the photo, since I stir in the bloom and tap the V60 in this example, resulting in a big change in the scale's data. But I can use the slopes shown in the graph easily.) With all my experience, I can say that fixing all the other variables, I could create completely different brews with different pouring rates. Thus, with the fast responding and Bluetooth interfaced Acaia, you can play with the pouring rates by analyzing your data and decide on the best one on your own taste. Plus, with this application you can take notes on your brews including many variables such as temperature and grind size. There is also a social network between users where you can share and learn about all the other user's brews. 

Bluetooth connectivity has two more advantages for me: The scale is available to be updated with a new firmware over internet - including the functions of two keys on minimal design of Acaia. This can be a very crucial feature since user's may need different functions as time passes. I should confess that this can be a very specific feature, but if you are demonstrating brew ratios and timings to an audience - maybe during workshops as you can see in the photo - you can make it easily by connecting the scale to an i-PAD. This way you can reach to more people.

I need to mention that there is also a black model for the Acaia Pearl. (The one you see in my photos is Acaia Pearl White.) Besides, the ultimate scale lately produced by the company is Acaia Lunar, which can even be located on espresso trays with its small footprint and totally water proof design. You can see all other details from here - on their website: http://acaia.co/                       

Cafflano Klassic - All In One Coffee Maker - Some Notes from A Home Brewer

Looking like a big thermo-mug at first sight, Cafflano Klassic is certainly one of a kind with its ultimate practical advantages in carrying all necessary equipment for fresh coffee brewing in a compact form. 

Detaching the upper part by twisting, you face the grinder which seems an equivalent of a Hario Skerton with a rough evaluation. The intention of the design is to use the grinder with the below part so that what you grind fills the metal dripper located just below the grinder. The design allows you to put them on the smallest scales on the market and measure the amount of beans. There are just two disadvantages: The design has no tiny bell to grab strongly while grinding and it makes hard to grind light roasts. There are no covers for grinder and while trying to grind fast it is not easy to prevent some beans to spread at first trial - you can learn in time not to bend a lot.

The detached part is not a kettle but a "pouring apparatus" with which you can pour in a controlled way - but not as controlled as a dedicated kettle you can find from Hario and Bonavita. Be careful while pouring hot water from a kettle since the small detail in the bottom can result in some dangerous gambols. Use the red cover (detach it and put it over the pouring apparatus) to keep the water hot. Another warning is for the pouring rate: Don't try to be so fast and increase the decline a lot, otherwise some hot water can get over the limits. 

The dripper is a metal one and not surprisingly the ouputs are similar to what you can get with metal filtered chemex. Although the below cup seems large, taking the immersed part of the dripper into account I can easily say that the dripper performance and all other sizes are optimized for a single cup of 200 grams. For more coffee you had better grind very coarse because the drip rate is very slow and the filter size is very small. Filling the pouring kettle twice maybe necessary for more brew amounts. 

For me, it is critical to clean and dry the parts of the dripper and the below cup before gathering the Cafflano, because wetting the grinder for the next grind can be a messy experience. 

As a summary, I found it a very practical design for fresh good coffee in anytime anywhere just with a scale and hot water addition to the bag. There were certainly some small issues to be fixed if I were in the designers' shoes but they are not in front of the functionality success of Cafflano Klassic.

My Brewing Notes for A Sample from Probador Colectiva, İstanbul

La Niebla El Carmen Guatemala - Probador Colectiva, İstanbul

Altitude: 1800-2000

Varietal: Red Bourbon, Catuai

Harvest: April - July 2015

Process: Washed

Bright Citrus Acidity
Complex Fruitiness
Clean Aftertaste





I have chosen 95 degree Celsius for all brewings unless otherwise noted. I could start to taste the beans 7 days after the roasting date.

1. Tasted with V60 V01 with a ratio of 12/200gr with stirring in pre-infusion and tapping in the last 1 minute, with a grind size of 10/40 over Baratza Virtuoso. Poured in 3 steps including pre-infusion - 2:20 total time with 45 seconds pre-infusion: The bright acidity is obvious. There are some flowers as well as fruits in the middle and the aftertaste is really clean. But I am sure I can get a better result with increasing the ratio a bit and going to a coarser grind size.
2. Tasted with V60 V01 with a ratio of 20/300gr no stir no tap, with a grind size of 16/40 over Baratza Virtuoso. Pre-infused for 45 seconds: My overall best result with this coffee with respect to my own taste. Even it is not in the cupping notes of the roaster, I feel very happy to get some chocolate flavors after the first second besides a very balanced output composing all the cupping notes -not surprising in my opinion for beans from Guatemala. 
3. Tasted with Chemex 6 cup with a ratio of 15/225gr with a grind size of 20/40 over Baratza Virtuoso. 45 seconds Pre-infusion time: The fruitiness is dominant in the cup but I feel a weakness in the aftertaste. I can go a little bit higher ratios such as 24/360gr or even 26/340gr with the same grind size. 
4. Tasted with Aeropress with a ratio of 18gr/250gr with a grind size of 10/40 over Baratza Virtuoso. 30 seconds pre-infusion with 50 grams and pressed in 20 seconds. Total brew time is 3:00: The first hit is too acidic in my humble opinion even for a bright acidic coffee. I may try a slower press or try a lower coffee/water ratio.  
5. Tasted with Aeropress with a ratio of 16gr/255gr with a grind size of 10/40 over Baratza Virtuoso. 30 seconds pre-infusion with 50 grams and pressed in 30 seconds. Total brew time is 2:30: Acidity is more balanced compared to my other aeropress trial.
6. Tasted with Kalita 155 with a ratio of 18/250gr with a grind size of 20/40 over Baratza Virtuoso. 50 grams pre-infusion in 45 seconds. Total brew time is 2:00 with pulse pouring: The first hit is a little bit too acidic again. Plus the fruity notes seems to be closed by this acidity. But I have to confess that the aftertaste impressed me much more with its strength.
7. Tasted with Kalita 155 with a ratio of 20/250gr with a grind size of 25/40 over Baratza Virtuoso. 50 grams pre-infusion in 45 seconds. Total brew time is 2:00 with pulse pouring: One of my favourite results for this coffee. I have a very balanced thing in my mug and I feel like I am very close to the cupping notes of the roaster. 

My Brewing Notes for Two Samples from Five Elephant, Berlin

Five Elephant – Ethiopia Bifdu Gudina - Agaro, Kaffa 

(Roasted on February 21st – <Light-Medium>)

Varietal: Heirloom

Harvest: December 2014

Producer: Oromia Coffee Farmers Cooperative 

Union, Aprrox. 130 smallhold farmers

Process: Washed & sun-dried on raised beds 

Elevation: 1800-1900 masl.

Flavor: Floral Notes of Magnolia with Citric Acidity, Plum Sweetness and A Spicy Finish

I have chosen 95 degree celsius for all brewings unless otherwise noted. I could start to taste the beans unfortunately 10 days after the roasting date.

1. Tasted with V60 12/200gr with stirring, with a grind as fine as aeropress – i.e. just a little bit coarser than espresso: A very dominant citric acidity is very well finished with a soft earthy feeling which does not conflicts with the roaster notes as spicy finish. As time goes by it passes through a spicy feeling and stays really like a plum (not too sweet). My favourite in all methods I have tried.
2. Tasted with Chemex 15/225gr (approx. 30/40 grind with Baratza Encore): The heavy spicy smell that you can easily get, just after grinding these beans is successfully projected into this brew's aftertaste. Plus the plum sweetness seems to be maximized. In contrast, the citric acidity is minimized. 
3. Tasted with Aeropress 18gr/250gr with a grind just a little bit coarser than espresso: The body is well dominated compared to V60 but the floral heaviness of the bean –thanks also to its freshness- is so overwhelming that all the entrance, first touch to the upper part of the tongue and the long term aftertaste became something really unique with the aeropress.
4. Tasted with Kalita 20/300gr with a grind as fine as chemex in my experiment: The first hit is too acidic in my humble opinion with this grind size, so when I tried a little bit coarser but even grind, the result is a better and balanced extract. The spicy finish is very well defined and the strong floral notes and acidity is fairly softened.

Five Elephant – Kenya Kamwangi AA – Kirinyaga District, Central Kenya 

(Roasted on February 21st – <Light-Medium>)

Varietal: SL 34

Harvest: January 2015

Producer: New Ngariama Cooperative

Process: Washed & sun-dried on African beds 

Elevation: 1800-1900 masl

Flavor: Vanilla and blueberry with a transparent creamy body and citric acidity.

I have chosen 95 degree celsius for all brewings unless otherwise noted. I could start to taste the beans unfortunately 10 days after the roasting date.

1. Tasted with V60 12/200gr with stirring, with a grind as fine as aeropress – i.e. just a little bit coarser than espresso: The introduction is very soft and creamy and the aftertaste carries impressive vanilla notes. I may call a little bit too acidic for what's coming next to first creamy feeling. 
2. Tasted with V60 12/200gr with stirring with generally accepted standard as 17/40 in Baratza Encore: Better than finer grind size. More balanced but I am stil a little bit suspicious about what I am drinking. I may play with another variable controlling the extraction level. 
3. Tasted with V60 12/200gr without stirring with a grind as fine as aeropress – i.e. just a little bit coarser than espresso: Surely, a more balanced extract compared to my other V60 experiments. The creamy feeling, vanilla and acidity are all there in very balanced portions.
4. Tasted with Chemex 15/225gr, with a coarse grind like 30/40 of Baratza Encore: My favourite result compared to all others. No detectable flaw exists and the citric acidity is comparisingly soft in this brew. For the body, it may be more visible and I think we can get this with 24/360 gr ratio.
5. Tasted with Aeropress 12/175gr with a grind just a little bit coarser than espresso: Acidity is very well more visible than V60. It is the first feeling you get with or without slurping. Vanilla is still evident but blueberry seems to be hidden behind something. The body is more dominant compared to V60 results and it is really creamy consistent to the roaster’s cupping notes.
