RHS’s Oyster Guide


Tasting an Oyster 

Briny, juicy, and plump, oysters are one of the few delicacies that taste like the sea. The subtle differences between the East and West coast varieties are what keeps oyster lovers hooked. To be a full-fledged ostreaphile (an oyster lover) you need to explore the full range of styles and varieties. Luckily, you can explore the different East and West coast varieties at our store (https://sfrhs.com/product-category/oysters/). To help navigate your oyster sampling journey, we have created this comprehensive guide directing you through the nuances of oyster tasting.  For those of you who do not like raw seafood, we have the perfect recipe for Oyster Rockefeller [here].

According to oyster connoisseur, Rowan Jacobsen (2008), when tasting an oyster, there are three stages. The first stage involves salt, the second stage body and sweetness, and the third floral or fruity finishes. Upon first taste, salt hits immediately when you tilt an oyster into your mouth. During the second stage, contrary to the popular belief that you should slurp oysters down, without chewing you miss out on the toothsome pleasure of the oyster. Biting into an oyster should be a similar experience to biting into fresh fruit, with some initial resistant before breaking. Chewing is what also releases some of the sweetness. The final stage is what is generally known as finish, which is described as the lingering flavor of the oyster after you have swallowed and chewed. Common finishing notes are cucumber and melon. 

The 5 species of oysters  

There are just five species of oysters cultivated commercially in North America. Each has classic characteristics, though they can be expressed quite differently, depending on location and growing conditions. The five species are:  Eastern (crassostrea virginica), Pacific (crassostrea gigas), Kumamoto (crassostrea sikamea), European Flat (ostrea edulis), Olympia (ostra conchaphila). 

Our Oysters

We carry Eastern, Pacific, and Kumamoto oysters. When trying each oyster see if you can catch the subtleties in taste as described below:  

Beau Soleils (crassostrea virginica) – Clean, light, and refined with yeasty, warm bread aroma.  These oysters are pair great with a nice glass of champagne to complement their light sweet flavor.

Fanny Bay (crassostrea gigas) – Smooth with a pronounced cucumber finish.  Pairs nicely with a full bodied pinot grias and pinot gricio to really bring out the smoothness of the oyster.

Kusshi (crassostrea gigas) – Petite with an ultra-clean flavor.  An effervescent citrus cocktail is an great match for Kusshi’s, as the addition of salt helps the cucumber and grassy notes to shine through.

Kumamoto (crassostrea sikamea) – Petite with a sweet fruity flavor. A nice dry wine would pair nicely with kumamoto’s as the high acidity balances out the oysters salinity.

Oyster Seasonality

Back in the day, the oyster eating rule of thumb was only to eat oysters in months that end in ‘R’. This is because in the warmer month’s oysters begin to spawn. Thankfully, farming practices have allowed oysters to be available year-round, but it is still possible to receive spawny oysters. You can identify a spawning oyster by pricking the meat, if the liquid looks milky it is a sign that it may be full of gametes. 

Oyster Farming & Sustainability 

95% of oysters that are eaten in the United States are farmed. In the late 1800’s, the combination of overharvesting and increased erosion finished off virtually every natural oyster bed in the United States. Since adopting a variety of aquacultural practices, farmed oysters have improved the surrounding environment by filtering and cleaning the water in which they grow (Jacobsen 2008). Farmed oysters are ranked as Best Choice across the board by the Monterey Seafood Watch Program.
