A certificate of origin is a signed document that accompanies a specific bottle in a closed edition. It names the producer, the bottle's individual edition number, the production date, the conditions under which the bottle was produced, and — in the case of kosher-certified spirits — the rabbinical authority that supervised the production. The certificate is signed by a named person within the producing house, typically the founder, master distiller, or certifying rabbi.
The certificate survives the bottle. Once the spirit is consumed, the certificate remains as the documentary anchor of the bottle's identity and provenance. For heirloom-grade dedications — Bar Mitzvah, anniversary, donor recognition — the certificate often carries longer-term significance than the bottle itself.
Every Tannenblut Bereshit bottle ships with a certificate of origin appropriate to its tier; the Founder's Tier carries a hand-signed certificate issued under founder oversight.
