1. Conclusion of the Exquisite Zone: The "Shoulder" of the Cluster and the "Bottom" of the Berry

To the conclusion.The sweetest "exquisite part" is the bottom side of the berry attached to the upper part (shoulder) of the cluster. In materials for cultivation and harvesting sites and interviews with domestic producers,it is repeatedly shown that the upper part of the cluster tends to lead in ripeness (sugar content) and aroma.Fruit and Vegetable IPM BlogYMAWSProduct Inspection CenterWeather News

Tips for Eating (Conclusion Version)
① Eating from "bottom (tail) → top (shoulder)" ensures increasing sweetness until the end.
② When serving on a plate,mix shoulder berries and tail berries equallyso everyone can enjoy the same sweetness.Product Inspection CenterWeather News

2. Why the Shoulder is Sweet—Ripeness and Sugar (Brix) Disparity

Grapes do notripen at the same speed all at once within a cluster, so it is normal for ripeness to progress in the order oftop = shoulder → middle → bottom = tail. Research and practical guides clearly state thatshoulder berries mature more than tail berries, and recommendmixing shoulder, middle, and tail for sampling to average.YMAWS

The **soluble solids content (SSC = Brix)**, an indicator of sugar, increases with fruit maturity, while acidity decreases. Differences also arise due to sunlight, temperature, ventilation, and fruit load, sothe taste changes based on the position within the cluster (shoulder/tail) and whether it's in the shade or sunlight.BioMed CentralYara Ireland

3. Is There a Sweetness Gradient Within a Single Berry?

Interestingly,the perception of sweetness can differ between the top and bottom of a single berry. Interviews with domestic producers and taste explanations suggest thatthe bottom side of the berry (the side farthest from the stem) tends to be perceived as sweeter and more aromatic. Knowing this dual structure—**the top of the cluster is sweet, but the "bottom side of the berry is sweet"**—can greatly enhance your satisfaction when eating.Weather News

Additionally, citizen experiments have repeatedly reported results showing that **"berries closer to the branch have higher sugar content"** (though there are varietal differences).shokuota.com

4. Popular Varieties in Japan and the "Ultimate Way to Eat"

Shine Muscat (Edible with Skin)

Japan's "national ace."A high-sugar, low-acid variety that can reach around 18–25°Brix, withvery thin skin and a muscat-like aroma.Eating with the skinis the basic way.National Agriculture and Food Research Organizationspecialtyproduce.comPMC

Ultimate Way to Eat:

• First,eat 2–3 berries from the tailto acclimate your palate. Then move tothe shoulder berries.

• The **bloom (bloom)** on the skin is a natural wax and a sign of quality. If it bothers you, lightly wash it off just before eating.Bon Appétit

Kyoho & Pione (Rich Varieties)

Black varieties with deep richness. While it's common to peel the skin,the sweetness difference of shoulder > tailis similar.The bottom side of the berry tends to be perceived as sweeter, which is also common.YMAWSWeather News

Delaware (Small Berries)

Small and refreshing. Mostly seedless, and if chilled and eaten in the **"bottom → top" order**, it avoids monotony.

5. How to Choose Without Failing: Look at Color, Aroma, Bloom, and Stem

• Bloom (white powder): Naturalbloom. A natural wax that protects the fruit from moisture evaporation and pathogens, safe to eat. Even if it's rubbed off and less visible, it doesn't necessarily mean quality deterioration.Bon Appétit

• Stem (peduncle):The greener and more hydrated, the fresher. Browning indicates deterioration.postharvest.ucdavis.edu

• Berries:Plump and firm, without wrinkles, leakage, or mold.postharvest.ucdavis.edu

6. Serving and Eating Method: Practical Techniques to Enjoy Sweetness to the Last

1. Sequential Eating:From tail → shoulder, gradually boosting sweetness.Product Inspection Center

2. Uniform Method:Mix shoulder berries and tail berrieswhen serving. Everyone enjoys "just the right sweetness."Weather News

3. Taste the "bottom side" of a berry: If cutting, place the"calyx side" of the berry upand halve it. You can directly taste the juice and aroma from the bottom side.Cookpad

7. Correct Storage: Refrigerate Without Washing, Do Not Ripen Further

• Basics:Store unwashedin abreathable bag(such as the perforated bag from purchase) in therefrigerator's chill/
