How Much Cognac Should I Pour into a Glass?

How Much Cognac Should I Pour into a Glass?

Hook : The other night, I wanted to impress my friends with an XO I'd found at a wine shop in Cognac. I filled the cognac glasses to the brim, thinking I was going for it. Big mistake: the aromas were muffled, it was impossible to swirl, and I wasted half the bottle. (My friend Claire teased me for weeks!) Since then, I've been wondering: how much to pour to make a cognac sublime? We'll see about that together, don't panic, it's simpler than it seems.

Why Does the Quantity of Cognac Matter?

For Limonadier, it's important to pour the right amount of cognac into a glass ; it's not just a question of elegance. It changes everything: the oxygenation, the perception of aromas, the pleasure in the mouth. Too much, and you drown out the nuances. Too little, and the experience is frustrating. A wine merchant once told me: "A cognac is like a perfume; you need the right amount for it to express itself." And he's right. An article I recently read on a spirits blog talked about how about 80% of amateur tasters get the dose wrong. We're going to avoid that.

Question : What is the ideal amount of cognac in a glass?

Answer : 3-5 cl for a pleasure tasting, 2-3 cl for a rare vintage, 5-8 cl in a convivial context.

The Rule of Fifth: Your Basic Guide

Unlike wine, where you fill it a third full, for cognac, you aim for a fifth of the glass's capacity. Why? Cognac, with its 40% alcohol (compared to 12-14% for wine), is more concentrated. A small dose is enough to release its aromas. A 15 cl glass? Pour 3 cl. That leaves 4/5 of the glass empty—the essential aromatic chamber for capturing fruity, woody, or spicy notes. Plus, you can swirl the glass without spilling, which helps oxygenate it. (Incidentally, I learned this the hard way after getting my shirt soaked in a VSOP at a dinner party in Paris.)

Why Not More?

Overfilling (like 8-10 cl in a 15 cl glass) is a disaster. Not enough air for the aromas, which get stuck. It's like listening to a symphony with earplugs in. Worse, you can't swirl the glass without getting it everywhere. A sommelier explained to me that the surface area in contact with the air must be large for the cognac to "breathe."

Quantity by Context: Find the Right Dose

The amount of cognac tasting (secondary keyword) depends on the occasion. Here's what I've learned after years of testing (and a few memorable failures):

Pro Analytical Tasting (2-3 cl)

For a professional tasting, like a competition or analysis, experts pour 2-3 cl . Why so little? It allows you to taste several samples without saturating the palate. A tulip glass (10-15 cl) is perfect, filled to one-fifth. You observe, you smell, you taste in small sips. (I saw this in a workshop in Cognac, and frankly, I was amazed at the precision of the pros.)

Amateur Pleasure Tasting (3-5 cl)

For a pleasure tasting at home, 3-5 cl is ideal. This is the standard for a cognac measuring glass (secondary keyword). It provides enough substance to appreciate the aromas without wasting anything. In a 20 cl balloon glass, 4 cl is enough for a great experience. This is what I do now when I take out my favorite VSOP.

Friendly Context (5-8 cl)

For an after-dinner drink with friends, you can be more generous: 5-8 cl . It's still respectful of the cognac, but it creates a warm vibe. Be careful, choose a larger glass (25-30 cl) to keep the aromatic room. (One evening, I poured 6 cl for everyone for an aperitif, and everyone was delighted – except my wallet.)

Special Occasion, Rare Vintage (2-4 cl)

For a vintage or Hors d'Âge cognac, be stingy: 2-4 cl . These gems are rare, and every drop counts. A tulip glass, 2-3 cl, and you observe the evolution minute by minute. It's almost meditative. (I remember a 1975 vintage shared with my father... I still get chills from it.)

Question : How much to pour for an XO cognac?

Answer : 3-4 cl in a tulip glass, to respect its complexity and avoid over-oxidation.

Adapt according to the type of Cognac

The amount of cognac per glass also varies depending on the type of cognac. Each category has its own requirements:

VS and VSOP: Generous, but Not Too Much (4-6 cl)

VS (Very Special) and VSOP (Very Superior Old Pale) are fruity and approachable. They can be served a little more generously: 4-6 cl . Their straightforward profile (apples, vanilla) blossoms well with a little more volume. Perfect for a relaxed evening. But avoid going overboard, otherwise the alcohol will dominate.

XO and Hors d’Âge: Measured and Respectful (3-4 cl)

XO (Extra Old) and Hors d'Âge are complex, with notes of leather, dried fruit, or rancio. Pour 3-4 cl to let them express themselves slowly. A tulip glass is ideal. I tested an XO by pouring 5 cl once, and it was too much: the alcohol masked the nuances.

Rare Vintages: Minimalist (2-3 cl)

For a rare vintage, 2-3 cl is enough. You want to savor every micro-sip. A smaller glass (10-12 cl) allows the aromas to be concentrated. (A wine merchant in Jarnac had me taste a 1969 like this, and it was… pff, indescribable.)

The Role of Glass: It Changes the Game

The type of glass influences the cognac glass measurement (secondary keyword). Here are the main points:

• Tulip glass (10-15 cl) : Perfect for professional tasting or vintages (2-3 cl). Narrow shape concentrates the aromas.
• Balloon glass (20-30 cl) : Classic for amateurs, 3-5 cl for pleasure, 5-8 cl for conviviality. Large aromatic chamber.
• INAO Glass (15-20 cl) : Versatile, 3-4 cl for pro/amateur balance. (I use this at home; it's my go-to.)

A spirits blog explained that the balloon, while traditional, can be less precise than the tulip for delicate aromas. But hey, it depends on your mood.

Question : Which glass for which quantity of cognac?

Answer : Tulip (2-3 cl, pro/vintage), balloon (3-5 cl pleasure, 5-8 cl convivial), INAO (3-4 cl versatile).

Common Mistakes to Avoid

I made quite a few mistakes before I figured it out (and I still do, oops). Here are the classic pitfalls:

1. Overfill : More than 8 cl in a 15 cl glass? The aromas are suffocated, making it impossible to swirl. Solution: respect the fifth.
2. Too Little (<2 cl) : Frustrating, heating too quickly, not enough to enjoy. Minimum 2 cl, always.
3. Uniform Service : Pouring the same amount for a VS and an XO is a no-no. Adapts to the type (VS: 4-6 cl, XO: 3-4 cl).
4. Confusing with Wine : Cognac has 3x more alcohol. No third of a glass, otherwise you have a cocktail, not a tasting.

A sommelier friend told me, “Treat cognac like a treasure, not like orange juice.” That stuck with me.

Pro Tips for Dosing Correctly

• Test first : Pour 2 cl into a glass, taste. Too light? Add 1-2 cl. This avoids costly mistakes.
• Use a measuring cup : A pouring spout or a jigger (3 cl) to be precise, especially for vintages.
• Adapts to the moment : Chill night? 5 cl. Serious tasting? 2-3 cl. (I have an engraved jigger that my sister gave me; it always works.)
• Double service for guests : Pour 3 cl, wait 5 minutes, add more if necessary. It keeps things under control.

Conclusion: The Right Dose, It's You Who Decide

Finding the right amount of cognac per glass is a balance between respect for the product and personal pleasure. The rule of one fifth (3-5 cl for most) is your starting point. Adapt to the context – professional, pleasure, convivial – and to the type of cognac – VS generous, measured XO, precious vintage. Test, adjust, trust yourself. (I wonder if Claire will ever forgive me for this XO fiasco…) So, ready to pour just the right amount for your next cognac? Share your tips in the comments!
