Ethanol necklace | 18K gold vermeil
Around 7000 BC at Jiahu in central China, residue analysis of pottery shards confirms the oldest known fermented beverage. Ethanol predates writing. The simplest two-carbon alcohol, the molecule of every toast, every reaction solvent, every clinical antiseptic wipe. Worn here as a 26 mm 18K gold vermeil pendant.
The Chemistry of Ethanol
Ethanol (C₂H₅OH) is the simplest two-carbon alcohol, produced industrially by fermentation of sugars by Saccharomyces cerevisiae and other yeast strains. Louis Pasteur's 1857 work established that fermentation is the metabolic activity of living yeast cells rather than a purely chemical process, founding microbiology in the same paper. In humans, ethanol acts as a positive allosteric modulator of the GABA-A receptor (sedative effect), an NMDA glutamate receptor antagonist (cognitive effects), and a mesolimbic dopamine activator (reward signal). Metabolism runs through alcohol dehydrogenase (ADH) to acetaldehyde, then aldehyde dehydrogenase (ALDH) to acetate. The ALDH2*2 variant in roughly half of East Asian populations explains the alcohol-flush response. Ethanol is also the most-used laboratory solvent and the second most-produced industrial alcohol after methanol.
Who Tends to Wear This
- chemists at career milestones, especially in organic chemistry or fermentation science
- brewers, distillers, sommeliers, and beverage scientists
- microbiologists working on yeast biology or industrial fermentation
- clinicians in addiction medicine, hepatology, or alcohol pharmacology research
Most often given on a chemistry graduation, a milestone in fermentation science or brewing, or as a celebratory gift that carries the chemistry of the toast itself.

FAQ
Is the ethanol necklace meant for chemists or for people who like a good drink?
Both, in roughly equal measure. Working chemists and brewers buy it as a reference to the molecule they handle in the lab or the fermenter. Recipients who associate ethanol with celebration, hospitality, or a particular drinking culture buy it as a quieter scientific anchor for the social meaning. The pendant works for either reading without pinning itself to one. The molecule is older than writing, and its cultural and chemical significance overlap.
What does ethanol do in the brain?
Three main things. It enhances GABA-A receptor activity, the same target as benzodiazepines, which produces the sedative and anxiolytic effects. It blocks NMDA glutamate receptors, contributing to the cognitive and memory effects at higher doses. It activates the mesolimbic dopamine system, generating the reward signal that drives consumption. The combination is why ethanol is unusual: a single small molecule with three distinct neurochemical actions, which together account for its complex behavioural profile.
What size is the pendant and what chain comes with it?
18K gold vermeil over a sterling silver core, 26 mm pendant on a 45 cm gold vermeil chain (ø 1.8 mm) with a 5 cm extender. Nickel-free and hypoallergenic. Free worldwide DHL Express in 1-5 business days, with all import duties and taxes covered. 30-day “Love It or Return It” returns.
Is there a silver pendant version?
Not as a pendant. Ethanol is currently available as the gold pendant or as silver earrings. Other small molecules in silver, including caffeine and dopamine, exist as silver-pendant counterparts in the same chemistry-of-everyday-life cluster.
