The aroma of a medium-roast pour-over bean is not fully present the moment it exits the roaster. After roasting, the bean body continues to release carbon dioxide, and the volatile aromatics are still reintegrating; if brewed too early, the coffee bed expands noticeably, water tends to bypass, and the cup may have soaring aroma while the sweetness has not yet come together. Therefore, when selecting beans, look at the roast date and also allow them time to come into their own.
"Peak flavor window" is better understood as a period of active flavor expression, rather than the closer to the roast date the better, nor that it becomes undrinkable after a certain day. Medium-roast beans typically go through stages of vigorous degassing, unfolding sweetness, and a slow decline in flavor. Packaging, environment, and the beans themselves all change the rhythm; the date on the bag should serve as a starting point, not a mechanical countdown.
When purchasing, you can first work backward from your drinking frequency to determine the size. One cup a day, using 15 grams per cup, a 200-gram bag makes about 13 cups, covering roughly two weeks; if rotating several coffees at the same time, a small package of 100 to 150 grams is more comfortable. Beans arriving 3 to 10 days after roasting can usually be scheduled for drinking while resting, without fixating only on just-roasted batches for the sake of "freshness."
For medium-roast beans, 5 to 7 days after roasting can be taken as the starting point for tasting, and 7 to 21 days is often the stage where aroma, sweetness, and extraction stability are more harmonious. Dense beans, relatively light roasts, or complex natural-process batches may need more than 10 days; medium-roast beans with fuller development can be tasted a little earlier. These day counts are an observational framework; what's in the cup is the basis for judgment.
If you want a bright, juicy character, look at Front Street Kenya Little Tomato. Its main line is like the clean acidity of biting into a cherry tomato, followed by the sweet-tartness of smoked plum and a brown sugar finish. Start test-brewing about a week after roasting; if the entry feels tight, let it rest another two or three days; once the acidity and sweetness connect more roundly, sip it hot as a pour-over, and after it cools the fruit boundaries become easier to distinguish.
If you prefer lightness and a tea-like character, schedule Front Street Kafa Forest to open 7 to 14 days after roasting. In the hot cup, the bright aroma of orange-like fruit first surfaces, the middle turns to the soft sweetness of ripe apricot, and the finish brings an oolong tea-like aftertaste. It is well suited to drinking from hot to lukewarm, sensing it in three sips from the same cup, where you can often see the sweetness gradually move forward, rather than judging only at high temperature.
To observe the layered changes of a natural-process bean, choose Front Street Granja Estate Geisha and set the drinking point a little later, for example around 10 days after roasting. The floral aroma brings to mind orange blossoms, while the fruit note shifts among guava, apricot, and strawberry jam. Brewing a cup every three days, rather than drinking it all within a short period, makes it easier to see how the intense aromatics slowly become more expansive.
Opening the bag does not immediately take the beans out of their state, but oxygen, light, heat, and moisture will accelerate the loss of aroma. For daily storage, continue using the original bag with a one-way degassing valve, gently expel excess air after each take and seal tightly, and place in a cool, dry location without noticeable odors. A transparent jar in sunlight is not ideal, and a grinder hopper is not suitable for long-term storage either.
Although the refrigerator's cold temperature is low, frequent taking in and out easily brings moisture and food odors. If you expect to finish within about three weeks, room-temperature sealing is usually more worry-free; if you need to store longer, portion by single-dose grounds after the flavor has unfolded, try to remove air, then freeze. When brewing, take out one portion and grind directly, keeping the remaining small packets frozen, which reduces moisture exchange caused by repeated warming.
To judge whether the beans have entered a suitable stage, you can record three consecutive cups: write down the roast date, opening date, bloom condition, and the aroma and sweetness in the hot, warm, and cool cups. When degassing is too vigorous, the bloom foam is plentiful and the cup feels a bit loose; after the state unfolds, pouring is steadier and the acidity-sweetness connection is more complete. Such records are more informative than just smelling the bag opening.
Brewing can also make small adjustments following the bean's stage. When degassing is still heavy, extend the bloom to 40 to 45 seconds and make the pouring motion gentler; once in the active flavor window, return to the daily rhythm. If the aroma lightens in the later storage stage, you can grind slightly finer or raise the water temperature a little. Master this rhythm, and a bag of medium-roast beans will have a clear, coherent flavor trajectory from opening to finishing.
