Questions

Before you reserve.

When does Reserve ship?
Reserve cases begin shipping in Q3 2026, nationwide across the U.S.A., sequenced in the order pre-orders are received. You will receive a tracking notification when your case ships.
Why is Reserve a pre-order?
Reserve is produced in limited quantity, drawn from a single seasonal cycle in Ulleungdo. Pre-ordering reserves your allotment from the next bottling run.
Can I cancel my pre-order?
Yes. Your card is charged at checkout but the order is refundable in full at any time before it ships.
What makes Ulleungdo Proper Water different?
Ulleungdo Proper Water matures in an enclosed East Sea basin, independent of the global ocean circulation. It is among the highest dissolved-oxygen deep waters on Earth.
How should I drink it?
Refrigerate after opening. Best consumed within 48 hours for the cleanest mineral note. One bottle per morning, on an empty stomach, is the ritual we recommend.
