The Complete Guide to Caviar — Tasting, Serving, and Choosing

What Is Caviar, Really?

Caviar is the lightly salt-cured roe of sturgeon. Anything else — paddlefish, salmon, lumpfish, or trout roe — is technically "fish roe," not caviar. The distinction matters because true sturgeon caviar carries a depth of flavor and a textural pearl-pop that no substitute fully captures.

At Onyx & Pearl, every tin we sell is American sturgeon caviar, hand-tinned at our California facility from sustainably farmed fish. This guide walks you through how caviar is graded, how to taste it, how to serve it, and how to choose the right tin for the moment.

How Caviar Is Graded

Grades describe firmness, pearl size, color uniformity, and the cleanness of the finish. Within American sturgeon, four broad tiers cover the practical range:

• Classic — everyday-quality grade with balanced butter and brine, ideal as a first-time experience or a generous canapé.
• Royal — larger pearls, refined butter notes, hand-selected. A clear step up at the table.
• Supreme — connoisseur-grade with a deep nutty finish and longer aftertaste.
• Imperial — top-tier, rare grade with the longest aging and the most silken texture.

How to Taste Caviar

Taste caviar at refrigerator-cold, never room temperature. Place a small amount on the back of your hand, between thumb and forefinger — the warmth releases the aromas without distorting the flavor. Take a small portion with a non-metal spoon, press it gently against the roof of your mouth, and let the pearls release before swallowing.

Look for three things: an initial fresh-sea opening, a buttery middle, and a clean, lingering finish. Inferior product is dull on the opening, oily in the middle, or fishy at the close.

How to Serve Caviar

Keep the tin on crushed ice. Use a mother-of-pearl, bone, or horn spoon — never silver or stainless, which oxidize the roe. Pair with one or more of: warm blinis, plain boiled potatoes, crème fraîche, or simply a clean spoon. Avoid garnishes that drown the flavor (raw onion, lemon juice, capers — these are old French tricks for hiding low-grade roe).

What to Drink With Caviar

Three pairings rarely fail: chilled vintage Champagne, a dry Riesling, or a premium clear vodka served ice-cold. Each lifts the brine and resets the palate without overpowering it.

How Much Caviar to Buy

For a casual aperitif: 10–15 grams per person. For a dedicated tasting: 30 grams per person. For a celebration where caviar is the centerpiece: 50 grams or more per person. Sample tins (10g) are ideal for first-time guests; 250g and 500g formats are for parties and gifting.

How to Store Caviar

Keep refrigerated at 28–32°F. Once opened, consume within three days. Unopened tins keep through the printed best-by date.
