Matias Zeledon of Down to Earth Coffee in Costa Rica posted an interesting picture of coffee beans with different sizes on the branch. This is an example of why you have to hand pick coffee to only get the ripe cherries. Here is Matias’ description:
Happy to see the coffee healthy and developing well in the Providencia highlands farm. The different sizes of the green beans are produced by the different waves of blooming, which generate the different stages in the harvest. The big differences in size comes from the fact that this year we had rain on Feb 9th so the first blooming came early and that is why the beans look so well developed compared to the others. This also means that we are going to be harvesting coffee in early November, a sizable bunch and not just a few.
In Coffee Smoothie ONE I showed how to make a coffee smoothie with freshly ground coffee. Since writing that post I have probably made a hundred of them and have perfected the recipe.
First I purchased a few bottles of Lorina Lemonade at the grocery store. The drink is amazing but what I really wanted was the resealable bottles.
The bottles are strong and the seal is both interesting and functional.
Cold Brewed Coffee Syrup
Next rather than making small batches of coffee syrup I moved to a 12 cup French Press. I put in 150 grams of coffee and fill with water. After sitting 24 hours in the fridge I get a full bottle of syrup. This is basically triple strength.
The other bottle is sugar syrup. I tried cocoa rather than Quik and really liked the result. You have to change the amount of sugar syrup as cocoa has no sugar or sweetener in it.
The last change was adding a banana. One issue with the original recipe is the drink tends to separate into the ice on top and the fluid below. The banana adds a pulp that keeps the drink from separating. It also is more creamy.
Here is the revised recipe.
Iced Coffee Smoothie
1/2 cup Cold Brewed Coffee Syrup
1/4 cup cold Sugar Syrup
1 tbsp cocoa
1 peeled banana
1 1/4 cup cold milk
1 1/2 cup ice cubes
In a blender place Cold Brewed Coffee Syrup, milk, Simple Sugar Syrup, banana and cocoa
Recently I bought a commercial blender to make fruit smoothies. Being a coffee junkie I wanted a coffee smoothie recipe. Most recipes I found started with instant coffee – not going to happen. I tried making strong hot coffee, adding milk, sugar and ice and blending. The result was a bland cool drink. Yuch.
Then I found an article on making strong coffee base with a french press and cold brewing. Normal hot coffee uses 10-15 grams to a cup of water so this is 2 to 3 times stronger. Cold brewing also reduces bitterness. I have been working on this recipe for months and here is my result. It is interesting how the type of coffee bean and roast changes the taste. A full city roast of Sumatra is one of my favorites.
Since releasing the recipe I had found an improvement. By adding two tablespoons of powered milk the smoothie stays creamier longer and tastes more milk shake like.
For some of my coffee roasting experiments I wanted a scale I could connect to a PC or Mac. I looked at many scales and the Ohaus Scout® Pro Balance series was a nice blend of capability vs price. This series is designed for educational applications. RS232 (part 71147376) and USB (part 71147377) interfaces are available. This article documents the use of the USB interface. I assume the RS232 is identical as the user manuals appear identical except for how to connect to the computer.
Through interviews I conducted for Seattle Coffee Gear’s Coffee Review I have visited and talked with local professional coffee roasters around Seattle, Washington from Caffe Ladro, Caffe Umbria, Middle Fork Roasters, Velton’s Coffee and Zoka Coffee. Roaster set-ups vary in size, capacity and philosophy. The most common refrain was to pay attention to the sights, sounds and smells. Do not get distracted or try to multi-task. Focus on the roast.

Caffeine is released during roasting. Some of this caffeine crystalizes on the outside as the smoke escapes.
This is a HotTop roaster. The yellow devices on top are temperature probes. As the roast progresses, smoke escapes from the probe holder. Over time, amazingly intricate white crystal structures appear. These caffeine crystals are know as angel hair in coffee jargon.
These are microscope shots of the crystals after removed from the probe.
