Roast Coffee Pairing #22 - Varietal Influence: Pacamara v. Bourbon

We are revisiting this pairing idea since it is such a fundamental issue in coffee: how much the varietal character of the plant influences the cup flavor. First up we have El Salvador Siberia Estate Pacamara. We roasted this batch to a City+ level to highlight the cultivar flavor profile; this is tricky to do with this type of bean because I needed to stop the roast while 1st crack was still audibly ocurring. This meant final thermoprobe temperature of 420 degrees and roast times of 15 minutes using slightly smaller batch sizes than we normally do. Next we roasted Guatemala Finca San Jose Ocana which was roasted more in the Full City range and is a mighty dense little bean. So final thermoprobe temps were 434 degrees with roast times approaching 16 minutes. As for the cup comparison, the Pacamara has a floral sweetness, while the Bourbon has a maltier sweetness. These two are ideal examples of the variances in flavor due to cultivar.

Adding more images to our library of macro shots of coffee. Here I photographed coffee flowers, the leaf, leaf buds, some defects in green coffee and roasted coffee, and ...what the heck ... some bubbles. -Tom

Full City++ roast

This coffee has entered 2nd crack, and the increased porosity is evident, as well as pockets of migrating oils. This and many more interesting macro shots I have taken of green and roasted coffee, as well as coffee cherry, are now posted on the SM site and Flickr. -Tom

PINO Digital Kettle Pro

It might seem silly, but I am really excited about this kettle,  the PINO Digital Kettle Pro. I need a lot of hot water for cupping and brewing so having a kettle that works as well as this does makes a big difference in my day-to-day life.   I  have the bad habit of forgetting that I am heating water.  On the stove, I will evaporate a full pan of water before I remember I had it on the burner ... which led me to use the Bodum Ibis kettle.  It's a fine kettle, but I also forget about it, and then my water is cool and I need to heat it again. So here is the pretty sleek the Pino Digital Kettle Pro, an electric kettle that will heat water to a temperature that I preset, and hold it there until I am ready for it, or remember it, whichever comes first. It has a 50 oz (~1.5 Liter capacity), and the electric base is separate from the kettle top. It is 1000 watts, a bit lower than some other electric kettles, but will heat a full 1.5 liters from tap temperature to 205 in 9 minutes, and will heat 16 ounces of water in 2 minutes. It is pricey, but this paired with a Clever Coffee Dripper makes a great brewing set-up.
