Cognac and Brandy Buying Guide: How to Choose the Right Bottle in the UK

Buying cognac and brandy online can feel straightforward until you compare bottle sizes, ageing labels, alcohol units and serving styles. A familiar name does not automatically make a bottle suitable for your home bar, gift list or planned cocktail menu.

This guide explains the practical details that matter, highlights common purchasing traps and matches several options to different UK shopping needs. All alcoholic products mentioned are for consumers aged 18 and over.

Common buying pitfalls to avoid

1. Assuming cognac and brandy are interchangeable

Cognac is a type of brandy made in the Cognac region of France under specific production requirements. French brandy may be produced elsewhere in France, while brandy can also come from other countries. If regional origin matters to you, check the product description rather than relying on words such as “premium” or “traditional”.

2. Choosing a bottle size without considering the occasion

A 70cl cognac is a practical format for regular home use, gifting or serving at a small gathering. A 35cl cognac, such as a smaller Hennessy VS or Courvoisier VS bottle, can be more suitable for trying a style, preparing a gift hamper or keeping storage requirements modest.

Larger formats, including a 1-litre bottle, may suit frequent hosts or cocktail drinkers, but compare the total price and alcohol units before assuming the larger pack offers better value.

3. Treating ageing terms as a simple quality ranking

VS, VSOP and Napoleon refer to ageing classifications or product styles, but they do not tell you whether the flavour suits your preferences.

• VS cognac is generally associated with a younger, lively profile and is often selected for mixed drinks.
• VSOP cognac has a longer maturation requirement and may offer more developed fruit, oak or spice notes.
• Napoleon brandy is a separate brandy designation and should not automatically be compared directly with a cognac classification.

Always check the individual label, alcohol percentage, ingredients and serving suggestions.

Core specifications to check before purchasing

Bottle size and alcohol units

Most full-sized bottles in this selection contain 40% ABV and approximately 28 UK units per 70cl bottle. A 25ml serving is commonly around one unit, although the exact figure depends on the product’s ABV and should be checked on the packaging.

Three Barrels 1L is listed at 38% ABV, while some Bardinet VSOP products are listed at 36% ABV. These differences affect both serving strength and total units. UK Chief Medical Officers advise that adults should not regularly exceed 14 units per week. Alcohol should be avoided during pregnancy, and responsible consumption is essential.

Classification and intended use

For neat sipping, you may prefer a VSOP cognac or a mature French brandy with fruit, floral, oak or spice notes. For cognac cocktails, a VS cognac can be a practical choice because its lively character works with citrus, soda and other mixers.

Descriptions should be treated as guidance rather than a guarantee of personal taste. Look for clear information about origin, classification, ABV and net quantity.

Ingredients, allergens and storage

Spirits may list ingredients such as grape eaux-de-vie, water, sugar, caramel colour or sulphites. Courvoisier VSOP, for example, lists sulphites, while Hennessy VS 70cl also lists caramel colour and sulphites. If allergens are important to you, read the product label and online declaration carefully.

Store unopened bottles upright in a cool, dry place away from direct sunlight and heat. After opening, keep the cap or stopper tightly sealed. Brandy and cognac do not usually improve indefinitely in the bottle once opened, so avoid leaving a partly filled bottle exposed to air for extended periods.

Frequently asked questions

Is cognac stronger than brandy?

Not necessarily. Strength depends on the product’s ABV, not simply whether it is labelled cognac or brandy. Many bottles listed here are 36% to 40% ABV. Check the label and calculate servings using the stated alcohol units.

How long does an opened bottle of cognac last?

A tightly sealed bottle stored upright and away from heat can remain drinkable for a considerable period. However, air exposure can gradually affect aroma and flavour. For the most enjoyable profile, keep the bottle well sealed and follow any storage guidance on the packaging.

What size should I choose for a UK home bar?

Choose 35cl if you are sampling a style, buying for occasional use or creating a smaller gift. Choose 70cl for regular sipping, hosting or a standard home bar. A 1L bottle is more appropriate when you already know the spirit will be used regularly, particularly in cocktails or mixed serves.

When arranging alcohol delivery UK customers should check age-verification requirements before ordering. Keep alcoholic drinks away from anyone under 18, drink responsibly and compare the full product information before placing your order.
