What is Hand-Poured Blend Coffee?

What does hand-poured blend coffee mean? How is a hand-poured comprehensive blend different from single-origin beans? And how does FrontStreet Coffee adjust its autumn hand-poured blend?

Understanding Hand-Poured Blends

Hand-poured comprehensive blend coffee beans are also called formula beans, mixed beans, or simply blend beans. The English term is "blend coffee," a concept defined in contrast to single-origin coffee. The distinction is simple:

Single-Origin Coffee Beans: a bag of coffee beans in which every bean comes from the same origin.

Hand-Poured Comprehensive Blend Coffee Beans: a bag of coffee beans that contains beans from two or more different single origins.

Simple Examples:

1. Ethiopian Yirgacheffe Worka: this product name refers to coffee produced by the Worka cooperative within the larger Yirgacheffe region of Ethiopia. Every bean comes from Worka, so it is clearly a single-origin bean. Brew it and you taste the full character of Yirgacheffe Worka.

2. Red Velvet: a product name that shows neither country nor region is usually a comprehensive blend. Shops generally follow no fixed rule when naming these. Most like to give them pretty names based on the coffee's tone and mouthfeel; some simply use "Experiment No. X," while others choose names that seem to make no sense at all. It really comes down to the shop owner's taste. Fortunately, most shops will note clearly that these are hand-poured comprehensive blends, and some will list which single origins are combined.

Even so, "comprehensive blend" remains the usual label. After all, when this formula was developed, the three Yirgacheffes were treated as separate components with different flavors, then mixed and roasted in different proportions to layer different tastes. Calling them a comprehensive blend is therefore more accurate.

Purpose of Formulating Hand-Poured Comprehensive Blend Coffee Beans:

Hand-poured comprehensive blends are usually created for one of four purposes:

1. Dedicated Espresso Blend Formulas

In specialty coffee today, espresso blends remain mainstream. Espresso must be combined with dairy, and overly acidic coffee, or a single origin with too thin a profile, is less suitable for adding to milk.

Hand-poured comprehensive blends can create balanced flavors that work well with milk, making them ideal for espresso-based drinks.

From the two cases above you can see how many variations espresso blends allow, and roasting them to an ideal flavor greatly tests a café's understanding and combination of flavors. Judging the quality of an espresso blend has thus become one standard by which many people decide whether a café is good. Personally, though, I suggest not being so critical. Savoring, appreciating, and imagining other cafés' espresso blends will do you more good.

2. Suitable for Long-Term Supply:

This also relates to espresso. Generally, all of a café's espresso inputs follow strict proportions to keep every cup consistent. Among them, coffee beans have the greatest impact and cause the most trouble, especially when a single origin is used for espresso. You often face the problem of a particular single-origin bean going out of stock, and switching to another temporarily means having to readjust the whole formula.

3. Simulating Special Flavors:

This purpose is less common in specialty cafés. Most commercial coffees use comprehensive blends to correct flavor and imitate certain famous branded coffees.

The most common examples are so-called "Blue Mountain flavor," "Kopi Luwak flavor," and "Gukeng flavor." Products with these flavor names often contain no Blue Mountain beans at all; they simply use other coffees to imitate the imagined taste of Blue Mountain. They might, of course, add a small amount of the original origin bean. Gukeng coffee sold on the market, for instance, often contains less than 10% Gukeng beans, with large amounts of coffee from other origins making up the volume.

4. Challenging Flavor Composition:

When a specialty coffee shop has the ability to formulate hand-poured comprehensive blends, it can sometimes create several different flavored blends, making the shop's drinks more varied in taste.

From the perspective of moisture content, two washed beans are fairly similar. In bean quality, Typica is softer, while Yunnan beans, with their relatively large particles, are similar to Kochere beans, which are harder but smaller, in heat conduction. Mixing these two for roasting does not easily produce uneven results. We also use a step-by-step heat-reduction roast: after dehydration and homogenization, there is a longer Maillard phase so the two beans develop more synchronously.

FrontStreet Coffee's Autumn Blend Adjustment

In deciding the roast level, we also took the "middle value" approach. This development time and drop temperature effectively remove the acidity and excessive herbal notes that appear when Yunnan coffee is roasted too lightly, while preserving the floral and fruity aromas of Yirgacheffe.

Roasting Machine: Yangjia 600g

Bean input: 300g, input temperature 170°C, heat off while charging. After 30 seconds, turn the heat on to 140 with the damper at 3. When bean temperature reaches 140°C, reduce heat to 120 and open the damper to 4. Dehydration and yellowing occur at 4 minutes 30 seconds. At 168°C, reduce heat again to 90. First crack starts at approximately 8 minutes, with the damper opened to 5. First crack development runs 1 minute 45 seconds, and the beans are dropped at 195°C.

On proportions, we first chose Huaguoshan to Kochere at a 6:4 ratio. Cupping results: good cleanliness, sweet and clear, with apple fragrance, plum acidity, and an orange aroma in the aftertaste. Overall impression: good mouthfeel but slightly thin in flavor.

Blend Adjustment

After cupping and discussion, we decided to add a flavor-enhancing bean, the Geisha Village Geisha natural process. This time we used a ratio of Huaguoshan to Kochere to Geisha of 6:3:1.

Reducing the Kochere proportion made the blend's overall acidity smoother than before, and the 10% Geisha Village brought more fruity flavors and enhanced the floral notes and tea-like qualities in the finish.

In roasting, to preserve more floral and fruity aroma, the drop temperature was lowered slightly. The time from dehydration to first crack was shortened a little to retain more reactive compounds, and the first-crack development time was extended to develop flavor.

FrontStreet Coffee Recommendation

A hand-poured blend lives or dies by its components, and a washed Yirgacheffe is one of the most useful building blocks a roaster can have. FrontStreet Coffee's washed Yirgacheffe staple lot brings white jasmine, bright citrus and lemon acidity, and a tea-like body, and its friendly price makes it the classic first specialty coffee for newcomers as well as a reliable base for blending.

For a more distinctive single-origin component, FrontStreet Coffee's Gotiti Cooperative lot from the Worka area of Yirgacheffe follows the most traditional washed processing and delivers fresh citrus and lemon brightness with jasmine fragrance instead of bitterness. If you want a fruitier accent to lift a blend's mid-palate, FrontStreet Coffee's natural Red Cherry adds juicy berry, honeyed sweetness, and a creamy texture from its fully ripe, raised-bed-dried cherries.
