FrontStreet Coffee - Pour-over Coffee and Coffee Tasting Introduction

The most fundamental difference between espresso and pour-over coffee lies in how they extract.

Espresso Coffee

Extraction principle: under 9 atmospheres of pressure, hot water at 90-94°C is forced rapidly through compacted coffee grounds. A single shot of espresso typically uses 7-8g of coffee, a double shot 15-16g, and the 30ml of concentrated liquid produced by this high-pressure extraction is what we call espresso. Built on that base, adding water, milk foam, chocolate sauce, or other ingredients in different proportions creates the whole family of espresso drinks — Americano, latte, cappuccino, mocha, and more.

Espresso beans are mostly used in commercial cafés, so they tend to be blends of workhorse commercial beans from origins like Brazil, Colombia, Vietnam, and Yunnan. Espresso beans are also usually roasted darker to keep the final drinks consistent.

Pour-over Coffee

Pour-over, as an extraction method, is known academically as "drip brewing," invented by a German woman, Melitta, in 1908 — the same Melitta whose filter paper brand is famous to this day.

Extraction principle: coffee grounds sit in filter paper or a filter, and hot water at 85-94°C is poured over them at normal atmospheric pressure, with gravity drawing the brew through by natural drip filtration.

Names like "natural Yirgacheffe," "washed Huila Colombia," and "Brazil FC natural" are single-origin bean names, typically telling you the origin, farm, or processing station of the beans and the processing method used.

Coffee Tasting

Step 1: Smell the Dry Aroma of Coffee

Bring freshly ground coffee close to your nose and you'll catch the dry aromas of different origins — the first information the coffee gives you. If coffee can be recognized by aroma alone, then your sensitive nose is your passport to the scents of the world's great coffee estates.

Step 2: Taste Its Flavor

Identifying the distinctive flavors of different origins is no easy task. The coffee liquid undergoes sensory analysis in the mouth, and with time and practice you'll learn to pick out each one.

Beans from different regions carry their own signatures: floral and fruity notes, nuttiness, tea aromas, ginger, pine, and many other peculiar tastes. Beyond taste, this step calls on your imagination.

Step 3: Perceive the Aftertaste

Tasting coffee is like tasting fine wine — it demands a finish. When you sip, don't swallow hastily; let the coffee linger at the back of your throat and feel the flavor rise back up. Some aftertastes are clear and persistent, others faint and brief, but all offer something wonderful.

Step 4: Understand Acidity

Many people — myself once included — don't particularly care for acidity in coffee, preferring the mellow, even slightly bitter cup that feels "strong enough." But if you want to become a true coffee connoisseur, you must first understand acidity.

Acidity is a perfectly typical, desirable part of coffee. It registers on the underside edges of the tongue and the palate, giving coffee a strong, distinct, lively texture. Without it, coffee turns monotonous and loses its flavor.

Step 5: Perceive Body

Body is the tactile sensation of coffee — the mouthfeel — ranging from light as water or skim milk to thick as whole milk, cream, or syrup. Use the middle and back of your tongue to feel its "weight." Whether you prefer light or full body is personal taste, but first you have to learn to perceive it.

Knowledge point: roasted coffee beans contain a wide range of organic compounds, especially acidic fats and volatile oils.

FrontStreet Coffee Recommendation

If the tasting steps leave you itching to practice, start with a bean whose flavors are easy to read: FrontStreet Coffee's Washed Yirgacheffe. Famous for white jasmine florals, bright citrus and lemon acidity, and a tea-like elegance, it tastes like a clean, refreshing lemon tea — which makes it ideal training for steps one through four, especially for learning what pleasant acidity actually is.

For practicing body, compare it against FrontStreet Coffee's Sun-Dried Red Cherry from the same Yirgacheffe region. Its full-red-fruit natural process — harvested cherries sun-dried on raised shelves and turned every 2-3 hours in the early days — delivers citrus acidity, berry juiciness, honey sweetness, and a cream-smooth texture that shows you just how different "weight" can feel in the cup.
