Gin 70cl Buying Guide: How to Choose the Right Bottle for Your Home Bar

A gin 70cl bottle is a practical size for personal use, hosting, cocktails or gifting. It is large enough for several serves without taking up excessive cupboard space, while offering more choice than smaller sample bottles. However, bottle size alone does not tell you whether a gin suits your taste or drinking plans.

Before you buy gin online in the UK, check the label rather than relying on front-of-pack wording. Terms such as “premium”, “craft” and “botanical” can describe a style or positioning, but they do not automatically indicate a particular flavour profile, alcohol strength or serving experience.

Common traps when buying a 70cl gin bottle

1. Assuming every gin tastes juniper-forward

Traditional London Dry gin generally places juniper at the centre, but modern flavoured gin and fruit gin can give greater prominence to citrus, berries, spice or floral notes. If you enjoy a classic gin and tonic, a fruit-led bottle may taste noticeably different from the description you expect.

Check the listed botanicals and tasting notes. Juniper, coriander, angelica and liquorice often indicate a more recognisable classic structure, while ingredients such as yuzu, strawberry, blood orange or rhubarb suggest a more contemporary serve.

2. Treating “flavoured” as a guide to sweetness

A flavoured or botanical gin is not necessarily sweet, and two bottles featuring the same fruit can taste very different. Some rely on natural flavours, while others may contain sugar, colourings or additional ingredients.

For example, the product information for Tanqueray Flor De Sevilla lists sugar, natural flavourings and colourings, whereas Copperfield Volume Three Citrus Spice Gin lists citrus and spice flavours without the same ingredient profile. Read the ingredients and nutrition panel if sweetness or additives matter to you.

3. Overlooking ABV and alcohol units

A standard 40% ABV gin in a 70cl bottle contains approximately 28 UK units. Higher-strength bottles contain more alcohol units even when the bottle looks identical. Tanqueray London Dry Gin 70cl is listed at 41.3% ABV, while Aviation American Gin 70cl is listed at 42%.

In the UK, spirits labelled as gin must meet the relevant legal requirements, including a minimum strength of 37.5% ABV. Always check the current product label, as descriptions and packaging can change. Alcohol is for adults aged 18 and over; follow UK low-risk drinking guidance and drink responsibly.

Core parameters to check before choosing gin 70cl

Flavour direction and botanical balance

Choose the profile that matches how you usually drink gin:

• Juniper-rich gin: Suitable for a classic gin and tonic, Dry Martini or Negroni.
• Citrus and spice gin: Useful for grapefruit or orange serves and more aromatic cocktails.
• Fruit gin: Often works with tonic, lemonade or spritz-style drinks, depending on the bottle.
• Floral or botanical gin: Can suit lighter tonics, soda and simple garnishes.
• Savoury botanical gin: Olive, basil, rosemary and thyme notes can complement food-led serves.

A craft gin may focus on a small-batch story or unusual botanicals, but inspect the actual ingredients and ABV to judge whether it fits your needs.

ABV, units and serving plans

For a home bar, 40% ABV is a familiar benchmark and works across many classic recipes. A 70cl bottle at 40% ABV contains 28 units, while a 41.3% ABV bottle contains approximately 28.9 units. A 43% ABV bottle contains approximately 30.1 units.

If you are buying a gin gift, a distinctive flavour or presentation may be more important than a small difference in strength. For regular mixing, compare the bottle price with the number of serves you expect to make.

Allergens, storage and product accuracy

Some gins list sulphites or nuts, including almonds. This is particularly important when buying for someone else. Check the allergen statement on the product page and packaging before serving.

Store gin upright, tightly sealed and away from direct sunlight or heat. Unopened distilled spirits can generally be stored for a long time in suitable conditions. After opening, air exposure can gradually soften delicate citrus, floral and fruit aromas, so avoid leaving a bottle loosely capped for extended periods.

Frequently asked questions about gin 70cl

How many drinks are in a 70cl bottle of gin?

A 70cl bottle contains 700ml. A typical 25ml measure of 40% ABV gin equals one UK unit, so the bottle contains approximately 28 units. Actual serves vary by measure and cocktail recipe. A standard gin and tonic may use 25ml or 50ml, so check your home measure when serving.

How should I store an opened bottle of gin?

Keep it upright in a cool, dark place away from sunlight and heat. Close the cap or cork firmly after pouring. Gin does not usually spoil quickly once opened, but its more delicate botanical aromas can gradually fade when exposed to air. Fruit and floral styles may benefit from being consumed sooner for flavour quality.

Which gin 70cl is suitable for cocktails?

A classic London Dry gin is a flexible base for a Martini, Negroni or gin and tonic. Citrus spice gin can add grapefruit, orange and warming notes, while fruit gin may suit spritzes and sweeter mixers. Match the garnish and tonic to the bottle’s stated botanicals rather than choosing by colour or presentation alone.

Only purchase and serve alcohol if you are aged 18 or over. Drink responsibly, never drink and drive, and follow UK health guidance on alcohol consumption.
