If you’ve never seen curves on the @decentespressomachines these won’t make a lot of sense. But see the green curves? They’re pressure curves from two shots. The pale green is mine, the bright green is by @mcolonnadashwood
What these curves show is that we’re both reasonably good at Espresso puck prep. They also show I’m stronger than Maxwell*
COFFEE TIP OF THE DAY!!! Warning: this one is extra nerdy...
I’ve realized the past couple of years that what we call “overextraction” is rarely, if ever, overextracted in the sense of “too much overall extraction.” Overextraction is always selective: bitterness and astringency show in the cup because of some combination of channeling (favoring some areas of the coffee bed) and overextraction from the surfaces of grounds (i.e. from fines). In percolation brewing, channeling seems to always play a role in “overextraction.” With most good grinders, it’s difficult to exceed 22% overall extraction before “overextracted” notes (bitterness and astringency) set in. However, some great grinders like roller mills can reach 26% or higher before signs of overextraction appear. The bottom line is that the overall extraction level at which a cup seems overextracted depends on the quality of the grind and the degree of channeling (NB: there is always a degree of channeling in percolation, even if it”s too subtle to see.) I would wager that a batch brew made from a stellar particle-size distribution could yield almost 29% overall extraction before bitterness and astringency become noticeable
1. COFFEE WAS ORIGINALLY CHEWED.
Some historians confirmed that the first African tribes consumed coffee by grinding the berries together, adding in some animal fat, and rolling these caffeinated treats into tiny edible energy balls.
2. DRINKING DECAF FUELS THE SODA INDUSTRY.
After coffee beans are decaffeinated, some coffee industries sell the caffeine to soda and pharmaceutical companies.
3. INSTANT COFFEE HAS EXISTED FOR NEARLY 250 YEARS.
Instant coffee has been around for a while, its first appearance was in England in 1771, but it would take 139 years for the first mass-produced instant coffee to be introduced and patented in the U.S. in 1910.
4. EVERY YEAR, MOST AMERICAN SPENDS MORE THAN $1000 FOR COFFEE.
No, an average of $1092 on coffee each year would not be enough to make America the world’s most caffeinated nation.
5. THE WORLD’S COFFEE CAPITAL IS FINLAND
Even though Finland does not produce any beans of its own, their citizens drink a lot of coffee.
6. BEETHOVEN WAS A BARISTA’S WORST CUSTOMER.
Beethoven loved his cup of joe, but very precise about the preparation. He wanted to consume it only if it was made with exactly 60 beans.
7. BRAZILIAN ATHLETES WAS SENT TO THE OLYMPICS BECAUSE OF COFFEE BEANS
Brazil couldn’t afford to send its athletes to the Olympics in Los Angeles, 1932, so they loaded their ship with coffee and sold it along the way.
8. SOME SEVERAL ATTEMPTS HAD BEEN DONE TO BAN COFFEE ENTIRELY.
In 18th century, governments were trying to ban coffee for the reason it could stimulate radical thinking. In 1746 Sweden took things to an extreme when it banned both coffee and coffee paraphernalia.

Who’s up for a cup of coffee?☕️ A few cups may be good for you; too many may be harmful.
Coffee beans have small amounts of magnesium, potassium, and niacin. They contain caffeine and are loaded with potent antioxidants. It may delay the absorption of blood sugar, increase metabolic rate, slower rate of weight gain as we age, and help blood vessels contract and relax.
🛑Stick to no more than 5 cups/day to keep your coffee intake at a safe level. However, in some people, too much caffeine (more than 300 mg/day) may lead to insomnia, nervousness, heart palpitations, and may also raise blood pressure. It may also interfere with sleep if taken after noontime. If you’re drinking coffee and getting less sleep every night, you may be putting yourself at risk for developing other chronic conditions over the long term. The negative effects of caffeine go away when you stop consuming it.
❌Be careful about what you add: cream, sugar, or sugary syrup. These contain saturated fat and empty calories.
¿A quién le apetece una taza de café?☕️ Unas cuantas tazas pueden ser buenas para ti; demasiadas pueden ser dañinas.
Los granos de café tienen pequeñas cantidades de magnesio, potasio y niacina. Contienen cafeína y antioxidantes potentes. Pueden retrasar la absorción de glucosa en la sangre, aumentar el metabolismo, disminuir la tasa de aumento de peso relacionado con la edad y ayudar a los vasos sanguíneos a contraerse y relajarse.
🛑No consumas más de 5 tazas/día. Sin embargo, para algunas personas, demasiada cafeína (más de 300 mg/día) puede causar insomnio, nerviosismo, palpitaciones cardíacas y puede aumentar la presión arterial. También puede interferir con el sueño si la consumes a media tarde. Si estás tomando café y tienes problemas para conciliar el sueño, te puedes estar poniendo el riesgo de desarrollar enfermedades crónicas, a largo plazo. Los efectos negativos de la cafeína desaparecen cuando la dejas de consumir.
❌Ten cuidado con lo que le añades: crema, azúcar o jarabe. Estos contienen grasa saturada y calorías vacías.
COFFEE TIP OF THE DAY!!! Although I’m not a fan of darker roasting, one problem with light roasts is that they often don’t translate well with cheap, home grinders. An acidic, fruity light roast is likely to taste sour or sharp when ground at home in a $40 grinder due to poor particle size distribution. Roasters may want to consider finding ways to accommodate the needs of consumers who use low-quality coffee equipment at home. Directing those consumers toward more-developed roasts would be one of the best options.
Caffeine is an ergogenic aid widely used before and during prolonged exercise. This is one reason why many endurance athletes and fitness enthusiasts like to have some coffee before hitting the gym or competing, since it’s known to be a performance enhancer and contributor to higher concentration and stamina

COFFEE TIP OF THE DAY!! Filters! Inspired by a comment today on my IG, I suggest you don’t think of filters as “metal” or “paper” but think of them in terms of porosity. Most metal filters may be more porous than most paper filters, but there are exceptions. The more porous a filter is, the faster coffee will drain through it, and more fines and oils will end up in the cup. More porous filters require finer grinds to reach a given extraction and TDS due to shorter contact time. I recommend never using cloth filters, as they impart rancid odors on brewer coffee after just a day or two of use, even if you clean them diligently (in my experience, many baristas using cloth filters just don’t notice the rancidity, which is shocking.) Test and compare paper filters for taste and odor by steeping them in hot water and tasting the water (thanks to @jimseven for that brilliant tip!) photo credit: @andrewrizer
I had the pleasure of touring a coffee plantation on my trip to Bali, and at the end of it I sampled a bunch of locally grown coffee and tea for a small fee. My fave was the Pandan Leaf Tea and Vanilla Balinese coffee. There was actually none I disliked which is unusual for me, a self proclaimed food critic 😂 One if the flavors I tried (although hesitant) was Luwak coffee... the beans are digested whole from a jungle cat-like animal and the beans are collected after. Yes, that’s right, the coffee is made from the droppings! I was assured the beans were cleaned thoroughly! They are boiled and dried in the sun. Luwak coffee is the most expensive coffee in the world and is considered a delicacy. Would you try? I have to say it was very smooth indeed!
COFFEE TIP OF THE DAY!!! A smaller roaster wrote to me this week asking how to manage roasting various batch sizes. He doesn’t have a cafe, so he has no outlet for extra roasted coffee (given that green coffee loses weight during roasting, a roaster must estimate the amount of green needed to yield a certain amount of roasted coffee; sometimes there will be extra.) He feels compelled to allow wholesale clients to order beans in any quantity they like. While that’s commendable service, that’s also a recipe for erratic roasting. I’d like to recommend that roasters with an outlet for extra green (e.g. they own a cafe) roast only one batch size of a given coffee. Roasters without an outlet for extra green should limit themselves to two batch sizes and perhaps no more than two roast days per week, in order to pool orders, which will help make those 1-2 batch sizes work out more easily. Attempting to manage profiles for 3+ batch sizes of a coffee is much more difficult than managing just one or two. And if at all possible, try to manage just one.

COFFEE TIP OF THE DAY!! This tip is from coffee-processing and fermentation expert @lluciasolis Lucia will make guest appearances here on occasion. Lucia will be offering some processing seminars in Seattle this April: see here or my recent blog post for tix:
It’s a myth that Brix of coffee cherry = Sugar content.
Brix is often used interchangeably with sugar content. A refractometer measures density - the total dissolved solids in any liquid - by measuring how much light is refracted by the sample. If there are few solids, very little light will be refracted and you will get a low reading. If there are a lot of solids you will get a high reading. But a refractometer does not single out sugar. I have dissolved salt in water to get a reading of 20 Brix even though there was absolutely no sugar in the sample.
Si bien el café es un gran aliado para el trabajo y la productividad de la mayoría de personas, existe un punto de quiebre en el cual pasa de ser un gran aliado, a un gran enemigo. 👇🏻👍🏻

Coffee is harmful only when used in excess.
These are the 2 main types of coffee bean used in coffee production. Characteristics of the arabica bean:
•Grown at a high altitude
•Pests •Lots of attention needed for growth
•Lower yield •1.5% caffeine •More expensive
Characteristics of the robustan bean: •Woody,earthy heavy •Grown at a lower altitude •Fewer pests •Less attention need for their growth •Higher yield •2.7% caffeine •Less expensive
Coffee beans come from inside the cherries that grow on coffee plants. Raw from the cherry we get a green bean. These green beans are then either left out to dry or dried by a machine before being roasted and brewed to drink. 🌿🍒☕️

COFFEE TIP OF THE DAY!!! another green coffee tip from Ryan Brown, author of “Dear Coffee Buyer”:
You’re better off buying an 86 early in an origin’s production season than an 88 two months later. While the former is likely to quickly make its way into the dry mill and onto a container towards you, the latter is increasingly prone to delays, quality depreciation, and disappointment. Better yet, hedge your bets by buying a bit of both.
Espresso se obtiene por un método de extracción del café realizado por medio de una máquina para espresso de origen italiano. El grano se muele finamente y se colocan 20 gramos en el filtro, se inserta en la máquina en donde por al rededor de 21 segundos el agua a 90ºC aproximadamente y 9 bares de presión realizan la emulsión, dando como resultado 2 onzas de café con un equilibrio en sabores de ácido, amargo y dulce. Está bebida es la base de la mayoría de las bebidas que se preparan en una barra de café. #extraordinarycoffee#tijuana#brewbar#sandiego#coffeelover#coffeefacts
Rise & grind, sunshine! Let's talk coffee ☕️ (caw-fee taw-k)
Coffee contains disease fighting antioxidants! 💪🏻
Coffee is great for your SKIN! Use it as a scrub to cleanse pores, brighten & tighten the skin & exfoliate it. The acid helps balance the PH of the skin. .
Decaf coffee can still prevent mental decline. Polyphenols help boost the brains cognitive abilities. These don't get lost in the de-caffeination process! 👍🏻
Coffee can help you not punch a co-worker in the face.💁🏼
Coffee can make women's boobs smaller!! 😵 Drinking more than 3 cups of coffee a day can apparently reduce the size of women's breasts #Notcool
Could cause ulcers, heartburn or digestive issues when overly consumed. 😬
Did you know that coffee makes you go 💩? The stimulative effect of coffee consumption on the colon is found in BOTH caffeinated & de-caffeinated coffee. It can happen as soon as 4 minutes after your first cup! Unfortunately this happens more to women then men 😑
Partial to a particular roast? DARK roasted beans actually have LESS caffeine than LIGHT roasted. Caffeine burns off during the roasting process, so the longer it's roasted, the less caffeine it has. .
I like to drink mine with Organic Cinnamon, Cayenne Pepper, 1/2 tbsp MCT oil, pinch of turmeric, & a splash of 100% pure organic maple syrup for sweetness. .
