This message serves as a legally non-binding yet morally compulsory pre-read for tomorrow’s Eggnog Competition (4:00–6:30 p.m. at the Rowayton Fire Department). Your attendance is expected. Your vote is assumed.

To be absolutely clear: you are not being asked to vote for Amazin’ Nog—you are being summoned to witness greatness and then behave accordingly.

Please arrive with a clean palate, as you would for communion, court, or a duel. It is essential that you taste Amazin’ Nog first, before your senses are corrupted by hobbyist noggers brandishing GMO eggs, discount bourbon, and reckless amounts of nutmeg.

Amazin’ Nog, by contrast, has its own appellation: grand grand cru. Few speak of eggnog’s terroir, and yet ours demands it. The eggs are pasture-raised and gently whispered to by Frédérique herself. The nutmeg is authenticated at the molecular level—a remedy to the historic fraud that earned Connecticut its infamous “Nutmeg State” reputation. The spirits are curated and blended under the stern yet loving gaze of master mixologist Christoph, an eggnog snob par excellence. Lastly, the cream is whipped by Sharon, whose Wisconsin dairy-forged wrists render silky soft peaks with airy consistency.

In summary, Amazin' Nog is Rowayton, distilled into a tiny paper tasting cup. Expect notes of vanilla, aged oak, righteous superiority, and—yes—just the faintest bouquet of leaf-blower exhaust, for authenticity.

Arrive pure. Taste wisely. Vote correctly. History is watching.
Please share this pre-read with friends and family.
