How Much Beer, Wine or Whisky Should You Buy?
Set the number of participants and how many drinks are in the lineup. We suggest a pour size that keeps palates sharp to the last item, then work out exactly how many bottles or cans to carry home.

How the calculator works
The math behind a tasting is different from party math. At a party you estimate drinks per hour; at a tasting the lineup is fixed and every guest tries every item. So the real question is pour size.
The calculator starts from your participant count and lineup, then recommends a pour that keeps the total per person sensible — big enough that everyone gets a proper taste of each item, small enough that palates (and judgment) survive to the last pour. From there the shopping math is simple: pour size × participants = liquid needed per beverage, divided by your bottle or can size and rounded up to whole containers, because shops don't sell half bottles.
Alongside the shopping list, it estimates how long the tasting will run, tracks the total volume and alcohol per person, and flags when a lineup leaves almost nothing spare — so you know when to buy one extra of anything you'd happily drink again.
Standard tasting pour sizes
| Beverage | Focused tasting | Standard tasting | Generous tasting | Full serving |
|---|---|---|---|---|
| Beer | 90 ml (3 oz) | 120 ml (4 oz) | 150 ml (5 oz) | 330–500 ml |
| Wine | 40 ml (1.4 oz) | 60 ml (2 oz) | 75 ml (2.5 oz) | 150 ml (5 oz) |
| Whisky | 15 ml (0.5 oz) | 20 ml (0.7 oz) | 25 ml (0.85 oz) | 40 ml (1.35 oz) |
Rule of thumb: the longer the lineup and the stronger the drink, the smaller the pour. That is why the calculator lowers its recommendation as you add items — six full glasses of anything is a party, not a tasting.

Frequently asked questions
How much alcohol should I buy for a tasting?
Multiply the pour size by the number of participants to get the liquid you need per beverage, then round up to whole bottles or cans. For example, 8 participants at 120 ml (4 oz) pours need 960 ml of each beer — three 330 ml cans. The calculator on this page does this for the whole lineup and produces a printable shopping list.
What is a standard tasting pour?
Roughly a quarter to a third of a normal serving: about 120 ml (4 oz) for beer, 60 ml (2 oz) for wine, and 20 ml (0.7 oz) for whisky. Small pours are the point — they let guests compare several drinks side by side while their palate is still fresh.
How many drinks should be in a tasting lineup?
Five to eight for beer, five or six for wine, and four to six for whisky. Fewer than four feels short; past the top of those ranges palate fatigue sets in and the last items get unfairly low scores. If you want a longer lineup, shrink the pours.
How long does a tasting take?
Plan roughly 8–13 minutes per item: pour, taste, talk, score. A six-drink lineup runs about an hour once you add the welcome and the reveal — longer if your group likes to argue about the scores, which is half the fun.
Is the calculator free?
Yes — free, no sign-up, and the shopping list downloads as a printable PDF. If you also want to run the tasting itself with live guest ratings and a final reveal, Tasteparty is free for up to 10 guests.
A note on drinking sensibly
A tasting is about comparing drinks, not finishing them. The calculator tracks alcohol per participant across the evening so you can see the pacing before you shop — put water and food on the table, keep a dump bucket within reach for anyone who wants one, and sort out how everybody gets home before the first pour. Nobody has to empty a glass to score it.
