coffee tastings

blind coffee tasting events


This defines a way to hold and score coffee tastings in such a way that the results from different events may be compared. Consider organizing such an event yourself, using the same scoring system, and emailing the results to c2builder at yahoo com.

Tasting Events

The overall goal is to find the best coffee to serve at home for ourselves and our guests. To remove the influence of advertisers, coffee house decor, and the like, we'll have a series of blind tasting events on weekend mornings, hosted by whomever feels like organizing it. A consistent scoring convention should allow the results of one to be compared with the results of other such events.

Because we intend to serve our chosen favorite at home, only typical, residential coffee equipment and techniques will be used. Since few if any use french presses, for example, we won't constrain our events to use such - despite the urgings of high end coffee shops.

Because each of us trying to make the best home coffee for our guests, the events will publish the raw score values from each participant as well as statistical means for each coffee. This mean score value is our best way, for now, of determining an overall winning coffee.

There is a lot of information available on coffee tastings at the professional level but their goals are different and their budgets unlimited (see, for example, link. We will borrow from their techniques as suits our goal.

For any particular event, some will bring coffee but all will be tasting. As the organizer starts contacting people, they'll be asked if they have a coffee they'd like to see tasted. If so they have to tell the organizer the particular and indicate whether they need to bring special equipment to make it. The people who make the coffee can elect to keep the name of the coffee secret but the organizer needs to see that there are no duplicates.

The organizer should also arrange to have on hand as many thermoses as there will be coffees to taste. Each thermos will be given a number to be used on the score cards.

An organizer chooses a guest list and a time and place for the event. The invitations can be made by email or phone, as the organizer chooses. The people who are going to make the coffee need to arrive a little earlier than the others. Note that someone wanting to bring McDonald's coffee, however, can just bring a thermos full of the purchased coffee. As people arrive, the organizer needs to hand out score cards and attach numeric labels to the various coffee containers. At the end of the tasting, the organizer has to score the event and announce which numbers correspond to which brands of coffee as well as how those coffees fared.

The scorecard just needs to have a place for the person's name and then a list of numbered lines for the ratings. The names of the coffees aren't written on the scorecards until the scores are announced.

The organizer may want to contribute his or her favorite coffee to serve as a standard for future comparisons. If, for example, I think Peet's French Roast is the best coffee, all events I host will include this coffee. I can compare the results from from January's event with May's and each set of results quickly reveals what people think might be better than my current favorite.

The organizer's last official duty is to email the results to me (c2builder at If the results are typed into a text file similar to this example, then I (frank, c2builder) can help crunch the numbers with a small program I wrote.

Rating LA  My new favorite! I will tell people about this!
Rating SO  very good! Would buy this even if guests didn't like it.
Rating FA  good. would buy this if I thought guests would like it.
Rating MI  no complaints but wouldn't seek it out.

Coffees to Taste

The following are just suggestions. Invitees can obviously choose whatever they want to bring. The collected notes, including prices, are here.

There's nothing against trying espresso's, various roasts, or coffee obtained in far-away lands. If you have a special way of preparing it (like adding whiskey), you can add it to the list. If your special coffee has to be sipped from a beer mug, be prepared to bring some mugs along with your coffee still.

If we're going to taste decafs, we might devote a whole gathering to just decaf.
