How We Calculate Exactly How Much Alcohol Your Event Needs

When you're providing the alcohol for your own event, it all comes down to one question: how much do I actually need?

The internet is full of rules of thumb. "One drink per person per hour." "Buy 1.5 bottles of wine per guest." Those formulas are fine as a starting point and pretty unreliable as a final answer.

Here's how we build your shopping list, and why our approach saves you money without ever risking a dry bar.

The Things That Actually Change the Number

Generic calculators treat every event the same. We don't. Here's what we account for when we plan yours:

  • Guest count. The obvious one. But not all of your guests drink, so we adjust for the typical 15-25% who won't.
  • Event length. A 3-hour reception and a 6-hour celebration have very different consumption curves. It isn't a straight line either, since drinking peaks during cocktail hour and tapers from there.
  • Time of day. Afternoon events go through 25-30% less alcohol than evening ones.
  • Season. A summer Oklahoma event leans heavily toward lighter drinks like ranch water, beer, and rosé. A winter event shifts toward whiskey, red wine, and spirit-forward cocktails.
  • Your drink menu. A beer-and-wine event needs different planning than a full cocktail bar with three signature drinks.
  • Who's coming. A wedding with a big 21-30 crowd drinks differently than one weighted toward older guests.

How We Model the Night

We plan your night in phases:

  • Cocktail hour (60-90 min): about 2 drinks per drinking guest. This is the peak, when people are social, standing, and ready.
  • Dinner service (60-90 min): about 0.5 drinks per guest, since consumption drops once food is out.
  • Post-dinner reception (2-3 hours): about 1 drink per hour per drinking guest, tapering toward the end of the night.

For a typical 4-hour event with 100 guests, that comes to roughly 358 total drinks, not the 500-600 a generic calculator would tell you to plan for. In real dollars, that lands your alcohol around $500-600 total, or about $5-6 per guest, instead of the inflated number a rule of thumb would push you toward. That difference is real money you'd never have opened.

The Safety Buffer

We always build in a 10-15% buffer. Here's why:

  • Some events run hot. A great band, a great crowd, and consumption climbs.
  • Spillage, over-pours, and garnish waste are real.
  • Running out at 10pm is a lot worse than having three extra bottles to return.

The buffer is deliberate, not lazy. We size it based on the risk factors for your specific event, so an outdoor summer party gets a larger cushion than an indoor winter one.

You Can Return What You Don't Use

This is the real advantage of buying your own: if you over-buy, you return the unopened bottles. Most Oklahoma liquor stores take returns within 30 days with a receipt.

We point you toward stores with flexible return policies and tell you which items make sense to buy in larger formats (handles save money) versus standard bottles (easier to return).

The Welcome Sips Advantage

For Luxe and Iconic tier events, our Welcome Sips feature adds another layer of precision. When your guests pre-select their opening drink through your wedding website, we can see the pattern before the event even starts.

"Once we know what guests are reaching for in that first round, we know the minimum of each beverage we need on hand," explains founder Patrick Wilson. "It lets us predict consumption more accurately using real data, so our clients spend less and never buy too much or the wrong drinks."

If 60% of your guests choose the signature cocktail over beer, we adjust your shopping list to match: fewer cases of craft IPA, more of the spirits in your signature. That's data doing the guessing for you instead of a rule of thumb.

Why It Works for You

Your shopping guide isn't a generic calculator with your guest count plugged in. It's a model built on data from hundreds of Oklahoma events, tuned to your specific event, and designed to save you money while making sure you never run dry.

"We make buying your own alcohol so easy that it is rarely worth paying a caterer to handle it for you," Patrick says. The result for you: you spend less, waste less, and your bar runs exactly as long as your celebration does.
