(Editor’s note: I’m very happy to be posting the first in what I hope will be a series of staff introductions, to be followed by regular postings by our barista team here at the 15th Ave cafe – we have a truly astounding amount of passion amongst our staff. A significant part of what we seek to accomplish daily in the shop is educational – both for ourselves and for our customers. Each interaction provides an opportunity for learning, and engaging in this conversation is hands down the most fun, and most important part of our day. Our daily 11am cuppings are always a learning experience, regardless of how many times we’ve tasted a particular coffee. Often, as Alex describes below, we use our cuppings as a laboratory to learn more about one particular coffee or one aspect of brewing coffee. Anyway you look at it, ongoing learning is critical and maintaining passion about learning may be the single greatest characteristic any barista can possess. Without further ado, meet Alex…)
Hi! My name is Alex, and I am a recent addition to the already amazing team here at 15th. As most of you probably already know, we host cuppings every day, without fail, at 11 am; most of the time we cup coffee, but every so often we mix it up and cup our fantastic full-leaf teas. Always a coffee lover, I have been developing my palate and expanding my knowledge through attending (and hosting!) our daily cuppings. The first tasting I did this week was a hybrid tasting with coffee and tea. I decided to do a comparison of floral, citrus and earthy flavors to taste the differences and similarities between coffee and tea. First was floral: I chose Panama la Esmeralda Diamond Mountain for the coffee and our First Flush Darjeeling tea. The Panama had light, fruity notes with sweet lime acidity and a perfumey, floral aroma. The Darjeeling, since it was a first flush, was beautifully delicate with a soft floral aroma, slightly nutty flavor and the perfect amount of astringency to finish it off. Next was citrus: the Kenyan coffee was fuller bodied, with intense grapefruit and orange flavors and a deeper acidity to balance it all out – beautiful, and one of my all-time favorites. Paired with it was our Earl Grey, a blend of Indian teas with bergamot oil from Italy. I was blown away by the balmy body the bergamot helped produce, and of course the delightful punch of citrus! Last came earthy: Sumatra was the coffee, from a region of the world known for its earthy, spicy, herbal coffees with thick, syrupy bodies. Our Sumatra has really been fabulous lately, exhibiting an intense buttery sweetness like crème brulee along with rich and savory herbs. I paired the Sumatra with our stoutest of teas, Yunnan Pu-Erh. It has a deep amber color along with the heaviest body of any tea I have ever tasted – it holds its own even against coffee. An aged Chinese tea, it has a more musty-earthy flavor, rather than a mushroom-earthy flavor, with a saccharine finish that lingers on the tongue. Amazing. 
At 15th, we are constantly discussing coffee. What brewing method is better, what amount of coffee to use, what grind is best, and the list goes on. This is important because we are constantly striving to make the best possible cup of coffee for you, our customer. Through scheduled cuppings and spontaneous daily tastings, we are able to learn why we do things, and more importantly, how to improve even more. Yesterday I chose to cup Ethiopia sun-dried Yirgacheffe, and to use the cupping as on opportunity to experiment with both grind and dose, thus ensuring that we would taste the coffee at a variety of stages in the brew process. Generally for our cuppings we use 14 grams of coffee with a grind setting that equates to a tight paper filter grind (a 14 on the Mahlkonig Guatemala Lab that we use in the shop). In seven cups I measured out 10, 11, 12, 13, 14, 15, and 16 grams of the Yirg, all ground on 14. Then, in seven other cups I put our standard 14 grams of coffee and used grind settings 10, 11, 12, 13, 14, 15, and 16. This is my inner scientist coming out now! Typically, it is understood that with a finer grind, a more intense favor is the result. From what I found in our lab, the cup with a grind setting of 10 (the finest in this experiment) was seriously muddy and over extracted, with the cups ground on 16 (the coarsest) being far too under extracted, with watery body and little flavor. The range with the best flavor was 13-15, with differing opinions on which was best. In the dose lab, 10 grams obviously didn’t cut it before we even broke the almost non-existent crust. 16 grams was far too much coffee, and tasted not too dissimilar from the coffee ground on the finest grind setting. Again, the range we easily agreed on was 13, 14, and 15 grams. Are these numbers making your head spin yet? When comparatively tasting coffee, people’s palates and hence their preferences tend to differ, so how to we decide on a ‘recipe’ for cupping that we use across the board? We think about all the levels of body and flavors that the coffee displayed in each cup, ranging across dose and grind setting, and then we pick the dose and grind and best represents the broadest range of these flavors and bodies.
In closing, I want to invite you to join us to one of our fabulous daily cuppings! Whether you just want to try different coffees to help you pick which ones to buy, or develop your coffee knowledge so you can rival the pros, there is always room at our cupping table for one more palate! See you at the cupping table…
