PROLOGUE

With so many new small retail and wholesale roasters coming into the trade in the late 1980’s and early 1990’s, it has become pertinent to review the factors influencing green coffee bean purchasing decisions.

Comparisons of Coffee and Wine by Carl Staub:

Specialty coffee is where the wine industry was 10-15 years ago., that is to say that, much like wine, coffee consumption is suddenly declining on a per capita basis. In fact, coffee is down roughly half from where it was in the early 60s. We see the same trend in the wine industry, people are drinking less but drinking better.

Roasting This Week: Costa Rica and Tanzania

We have so many great Costa Rica coffees right now, it would be a shame not to roast as many of them as we can before they sell out.

This Tuesday we will be roasting Costa Rica Helsar - Magdalena Vega. This coffee shines at a City+, so you can expect that it will be developed a little past first crack. The cup possesses the archetype of Costa Rica coffee character in nut-to-chocolate roast tastes and restrained sweetness of caramelized sugars that balance it out.

There's No Accounting for Taste

This has been a very challenging week for cupping. Why? I can't taste.

It all started on December 21st when we were flying to my sisters house in Tucson for Christmas. Ben turned to me on the airplane and sneezed directly into my gaping mouth. (I wonder if you can buy those full face shields the dentists use these days, for protection when your kid is sick. It's just a given he is going to sneeze directly on me at some point).

Taste Testing

There are a number of flavors that can found in a cup of coffee. Read the coffee reviews on this site and you'll see the mention of various types of nut, fruit, cookie/biscuit, etc. etc. These flavors are the result of the presense of organic acids and compounds and certain chemical and physical changes that happen during growing, harvesting, processing, and roasting.

Oh Nuts

 One question that we get quite a bit via the forum and otherwise is; What are some coffees with a nutty flavor profile? There are definitely coffees that have more of a nutty taste to them, but it would be very helpful to identify some specific types and/or reasons for this nuttiness.

Stretchin' Out the Roast pt. 2

 In part 1 of Stretchin' Out the Roast we looked at the effect of stretching out the time and development between 1st and 2nd crack during the roast. The greatest effect was on the perceived acidity and the type of sweetness in the cup from malt to candy, then fruit and  into bittersweet-cocoa-type sweetness. In this article we look at the effect of stretching out the 1st crack itself and how that changes the sweetness, body, and acidity in the finished roast.

Stretchin' Out the Roast: Part 1

Quality: 
5

This article details one method to determine an ideal roast for a coffee;  in four roast experiments, the time between the end of 1st crack and the beginning of 2nd crack is lengthened, and the roast stopped at the same point each time.  Then by tasting and comparing the results, I arrive at some conclusions about what roast brings out the characteristics of the coffee I enjoy more.  Other articles will cover the effect of stretching other segments of the roast.

1. We all Taste, why do we taste?

The famous non-attributable quote goes “Writing about music is like dancing about architecture”. Don’t try to tell me who actually said it first, that’s mostly unimportant. What’s important is that writing about any sensory experience is a rather challenging endeavor.

Coffee Processing Experiment: El Manzano

Video: 

We offered a set of three coffees from El Salvador - Manzano Estate some time ago, and it was a great educational experience I think. The set contained a single lot of the same coffee processed three different ways so you could taste what difference processing makes. Here are some notes from the review,

Silverskin on Green Coffee: Indicator of Cherry Ripeness?

Video: 

Taking a cue from a presentation that George Howell did at the Nordic Barista Competition on Silverskin separation, this video features Tom talking about the presence or absence of silverskin - what that might indicate and then cupping the results.

Home Barista Roasting Challenge Part 1 - Blended Coffees

Video: 

Home Barista hosted the second annual HB Home Roasting Competition. Tom was a judge for all the entries. The theme of this year's competition is to find the most complete home roaster.

The idea was that successful craft roasters must do two things well:
-- find rare and extraordinary coffees, and do them justice in the roasting.
-- make memorable and enjoyable blends from the more common good coffees.

Fruit or Ferment

I thought I had a good idea of what a fermented taint was but with discussions here and some of Tom’s latest coffee descriptions I am just confused now. So the question is: when does Intense Fruit cross the line into a Fermented Taint? Thanks, David
