Three Storage Principles: Tips to Keep Sake Happy

1. Above All, “Keep it Cold” – Temperature Management is Key

• Refrigerator temperature of 0-10°C is ideal
• Aromatic types like nama-zake and ginjo sake especially require refrigeration
• Never freeze! Freezing destroys flavor and aroma

The vegetable compartment of your refrigerator or a wine cellar works best for storage.
Leaving sake in a warm room can transform it into something completely different overnight…

2. Avoid Light – UV Rays are Sake’s Enemy

• Sunlight and fluorescent light cause aromas to dissipate and colors to change
• Brown and green bottles actually have UV-cutting features
• Dark storage is essential. Direct sunlight is absolutely forbidden!

The back of your refrigerator or shelves with high light-blocking properties are recommended.

3. Store Bottles “Upright”

• Laying bottles horizontally causes cap contact with sake, leading to deterioration
• Standing upright makes it easier to check for sediment

Storage Points by Type

Type	Storage Temperature	Consumption Timeline	Points
Tokutei Meishoshu (Junmai, Ginjo, Daiginjo)	2-8°C	6 months - 1 year	Refrigeration to prevent flavor deterioration
Regular sake, Honjozo-shu	Room temperature (cool, dark place)	6 months - 1 year	More stable, but refrigeration is safer
Nama-zake	0-5°C	3-6 months	Refrigeration essential! Deteriorates quickly
Aged sake	10-15°C	Several years	Watch for temperature changes and light

Common Storage Mistakes – Are You Making These?

• Leaving in door pocket → Severe temperature fluctuations cause easy deterioration
• Abandoning on kitchen windowsill or counter → Direct sunlight hits it
• Storing horizontally → Risk of cap damage
• Storing in entryway → OK in winter but hell in summer. Even room temperature has limits

“I display it on a shelf because it looks nice” – I understand the feeling. But then the contents are crying.

Post-Opening Handling Determines Fate

• Ideally finish within 1-2 weeks after opening
• Refrigerated storage is essential. Always tighten the cap securely
• If you can’t finish it, transfer to a small bottle to prevent oxidation ◎

Situation-Specific Advice

When Receiving as a Gift

Happy to receive premium sake as a gift. But neglecting it after delivery is NG.
If the label says “Refrigerate,” put it in the fridge immediately. Even without that instruction, a dark, cool place is essential.

When Buying During Travel

When bringing local sake home from travels, cooling bag + ice packs provide peace of mind.
Especially in summer, never leave it in a car. Your precious sake will become like a steam bath.
