Sanponashi Storage Recommendations

Our Hokkaido rice is current season new rice:

1. Packaging: Nitrogen-flushed (inert gas) packaging that reduces the rice's contact with air
2. Recommendation: Refrigerate immediately upon receipt
3. Quantity: We suggest ordering monthly so you can finish the rice while it is fresh
