Imbibing responsibly starts by keeping Mariette exclusively in hands of legal-drinking-age adults.
Here, we age-verify at three times the checkpoints than typical retail. As you enter the site, then when you purchase (as usual). Finally when product arrives, a government-issued ID must be presented.
By the way, valid US ID showing you are 21+ includes a US State issued photo drivers license, a US State issued photo ID Card, or a passport. Identification must not be expired.
