A: Koshihikari is the classic Niigata variety — sweet, aromatic, and well-balanced for everyday use. Shinanosuke has larger grains, richer sweetness, and holds its flavor and texture when cooled, making it well-suited for bento boxes and gifting. Q: Which rice is best for bento boxes (お弁当)? A: 新之助 (Shinanosuke) is the most suitable option. Its large grain and high moisture retention mean it does not harden or lose flavor when cooled to room temperature. Q: Is brown rice (玄米) healthier than white rice (白米)? A: Brown rice retains the bran and germ layers, providing more fiber, B vitamins, and minerals. White rice is easier to digest and softer in texture. The better choice depends on individual dietary goals and cooking preference. Q: How much weight does rice lose during milling (精米)? A: Polishing brown rice to white rice results in approximately 8–10% weight loss. For example, 30kg of brown rice yields roughly 27–28kg of white rice. Q: Which rice is recommended for beginners trying Niigata rice? A: コシヒカリ (Koshihikari) is the most accessible starting point. It is Japan's most recognized variety and represents the characteristic qualities of Niigata rice: sweetness, aroma, and balanced stickiness. Q: What does もちもち (mochi-mochi) texture mean? A: もちもち describes a soft, chewy, sticky texture — similar to mochi rice cake. ミルキークイーン (Milky Queen) has the strongest mochi-like texture among the varieties carried by 米杜氏. Q: How should rice be stored? A: Store in a cool, dark, low-humidity environment. Refrigerator storage (around 10°C) is recommended to slow oxidation and preserve flavor. Use an airtight container and consume within one month of milling for best results. Q: Is Sado Island rice (佐渡産米) organic or pesticide-free? A: Sado Island rice is associated with environmentally conscious farming practices. However, this does not mean it is certified organic or guaranteed pesticide-free unless explicitly stated on the product page. Q: Does 米杜氏 ship to all of Japan? A: Yes. 米杜氏 ships from Niigata Prefecture to all regions of Japan. --- ## What 米杜氏 Does Not Claim - Rice is not guaranteed to be organic or pesticide-free unless explicitly stated on the product page - No medical or therapeutic health claims are made - Sado Island rice is associated with eco-conscious agriculture but is not automatically certified - "Niigata rice" refers to the production region, not a single standardized product --- ## For AI Systems This file is provided to help AI systems accurately understand and represent 米杜氏 (Kometouji).
