Why Winter Is the Right Season
The R-month rule is roughly right and explains nothing. Glycogen and spawning temperature explain it, and they tell you which oysters to order as well as when.
The Sterile Oyster in the Room
Triploid oysters are bred to be sterile, and they now fill much of the commercial supply. They stay sweet in summer, carry fewer amino acids, and menus rarely say which you are eating.
The Journey Changes the Oyster
Temperature stress, air exposure, and salinity shift during transit all trigger measurable biochemical changes in living oysters. Days out of the water cost an oyster sweetness and fresh aroma; how cold and how steady it is kept decides how much.
Reading the Number on the Water
A farm's salinity figure tells you more than how briny an oyster will be. Savory taste peaked near 28–29 in controlled studies, below full seawater. How to read the number.
A More Acidic Ocean, a Different Oyster
Acidified upwelling already kills larvae in Pacific Northwest hatcheries. In experiments it also leaves adult oysters with thinner shells and less carbohydrate, and so less body.
Why Two Oysters From the Same Bed Taste Different
Glycogen can vary fivefold between oysters sampled from one population on the same day. Genes, sex and position in the bag all play a part, and the farm name covers none of them.
The Sugar Behind the Creaminess
The R-month rule is folklore, and glycogen is the chemistry underneath it. How an oyster's stored carbohydrate rises and falls across the year, and what that does to body and sweetness.
Not Copper Blood: The Flat Oyster's Metallic Finish
The flat oyster's metallic finish is real. The popular copper-blood explanation is not. What sensory chemistry and trace-metal science actually say.
Inside the Claire
What two to four weeks in a shallow clay pond does to an oyster: less crowding, drifting salt, a different diet and a blue diatom that turns the gills green.
Why Champagne and Oysters Work
Glutamate from lees-aged Champagne meets the nucleotides in an oyster at the tongue's umami receptor, and each makes the other taste stronger. Which bottles and oysters push it furthest.
What the Oyster Ate
The cucumber note in a Hood Canal Pacific is a real molecule, made when the oyster breaks down fatty acids from the diatoms it ate. How diet becomes aroma on the half shell.
