Shipping policy

Last updated: July 12, 2026

Gourmet Cultures ships to addresses within the United States. We do not currently ship internationally.

Processing time

Orders are prepared fresh and typically dispatch within 1–2 business days of your order. Because our liquid cultures are living biological products, we prepare and pack them close to ship time so they arrive lively. Orders placed on weekends or holidays are processed the next business day.

Shipping rates

Enjoy free shipping on orders over $50. Orders under $50 are charged a shipping rate calculated at checkout based on your order and destination. Any applicable rates are shown before you complete your purchase.

Carrier & tracking

We ship via USPS in protective mailers, and every order includes tracking. You'll receive a tracking number by email once your order ships. Delivery times vary by destination and are estimates provided by the carrier; they are not guaranteed, and Gourmet Cultures is not responsible for carrier delays once a package has left our lab.

Address accuracy

Please double-check your shipping address at checkout. We can't be responsible for orders sent to an incorrect or incomplete address, and we're unable to cover packages marked delivered by the carrier but reported lost or stolen.

Damaged or problem shipments

If your order arrives damaged, leaking, or showing signs of contamination, email us at support@gourmetcultures.com within 7 days of delivery with a clear photo and we'll make it right. See our Refund Policy for full details.
