BE IT A cocktail evening, dinner party or an informal gathering, running out of food and drink is every home host’s nightmare. So, estimating how much whisky you’ll need becomes the starting point for planning mixers, ice, and other bar essentials.
Here’s a handy guide to help you calculate the right amount of whisky for a 10-person party...whether you're mixing cocktails or serving it neat or on the rocks.
How many drinks per guest should you plan for at a party?
For a gathering that lasts 3-4 hours, it’s safe to plan for 2-3 drinks per guest. A standard whisky pour — whether in a cocktail or served neat — is around 30 ml per drink.
How much whisky do you need for cocktails for 10 people?
If you're using a standard 750 ml bottle, two bottles should comfortably cover 2 cocktails per person, with a little extra to spare.
Calculation:
2 drinks per guest × 30 ml × 10 guests = 600 ml
So, one bottle will cover the basics; crack open the second if anyone wants a third round.
What if guests prefer whisky on the rocks?
For those who enjoy whisky neat or with ice, a 30 ml pour still holds. You can even go with 25 ml if the mood is more "tasting session" than full-blown party. Two bottles still suffice.
Should you offer different whisky varieties?
That depends on your guest list. If your crowd includes whisky lovers, offering a mix adds flair. Aim for a smoky/peaty option, a smooth and sweet one, and a cask-strength pick for range.
But if whisky is just the cocktail base, a single versatile bottle will do.
So, how many bottles is that in total?
For cocktails: 2-3 bottles of 750 ml each.
For variety: consider smaller bottles of 2-3 different types.
What if whisky isn’t the only spirit on offer?
If your menu also includes wine, beer, or other spirits, you can scale down. Around 1-1.5 bottles should do, especially if guests will be sampling across options. This is also a great time to bring out premium whiskies for those who want a refined sip.
Do mixers or ice make the whisky stretch further?
Yes. When served on the rocks or mixed with soda, lime or ginger ale, whisky quantities can be dialled down slightly (for instance, with cask-strength or robust Scotch). Sometimes, even 20–25 ml is enough when balanced well with mixers.
