How Much Alcohol for a 300-Guest Wedding
Three hundred guests is the size where a wedding bar starts to look like an actual event bar: three stations, a reception length that swings the order by whole cases, and an order large enough that a case discount is worth asking for. Here's the exact list for a 4-hour reception and the specifics that come with this size.
For 300 guests over a 4-hour reception, plan for 1,200 drinks, then add 20 percent to get 1,440. At a wine-leaning mix that's about 144 bottles of wine (12 cases), 15 cases of beer, and 17 liters of liquor, plus mixers, 450 pounds of ice, and 900 cups. Staff 4 bartenders and a barback.
The full shopping list for 300 guests
This is a 4-hour open bar at the wine-leaning default of 25 percent beer, 50 percent wine, and 25 percent liquor, with a 20 percent overage buffer already built in. Every quantity rounds up, because running dry is worse than a few unopened bottles you can return.
| Item | How much | Notes |
|---|---|---|
| Wine | 144 bottles | 12 cases (12 per case); split roughly half red, half white |
| Beer | 360 beers | 15 cases of 24, or about 3 half-barrel kegs |
| Liquor | 17 liters | 1-liter bottles; about 22 cocktails each at a 1.5 ounce pour |
| Mixers | 100 quarts each | Cola, club soda or tonic, and ginger ale |
| Ice | 450 lbs | Double it for a hot, outdoor bar |
| Cups | 900 | 3 per guest across the night |
| Champagne (optional toast) | 50 bottles | One flute per guest, 6 flutes per bottle |
| Bartenders | 4 + barback | About 1 per 75 guests; barback recommended past 200 |
| Bartender tip | $200 to $400 | Cash at the end of the night, weighted toward the lead |
Where the numbers come from
Same engine as our wedding alcohol calculator: one drink per guest per hour, a 20 percent buffer, and published yields (5 pours per wine bottle, 24 beers per case, 22 cocktails per liter at a 1.5 ounce pour). The 100-guest list shows every conversion step by step. What's below is specific to 300: the three-station split, how reception length moves the order at this scale, and buying at wholesale volume.
A three-station bar plan
At 300 guests, two bars usually isn't enough to keep lines short, so most venues run three stations instead. Divide the list three ways and each station gets about 48 bottles of wine, 5 cases of beer, 6 liters of liquor, 150 pounds of ice, and 300 cups, every share rounded up so no station runs short before the others do. Spread the 4 bartenders roughly evenly across the three, and let the barback rotate to whichever station is backing up, rather than assigning them permanently to one spot.
How the list changes at 5 and 6 hours
The table above is a 4-hour bar. At 300 guests, every additional hour adds 300 drinks before the buffer, which is enough to move the wine order by more than a full case each step. Here's the same wine-leaning mix stretched longer:
| Bar open | Drinks to buy | Wine | Beer | Liquor |
|---|---|---|---|---|
| 4 hours (this list) | 1,440 | 144 bottles | 15 cases | 17 liters |
| 5 hours | 1,800 | 180 bottles | 19 cases | 21 liters |
| 6 hours | 2,160 | 216 bottles | 23 cases | 25 liters |
A 6-hour reception at 300 guests is a long day, and it's usually the ceremony-plus-reception-in-one-venue pattern rather than a separate cocktail hour tacked on. If your timeline runs that long, confirm the venue's pour cutoff and last-call policy before you finalize the order, since some venues stop serving 30 to 60 minutes before the stated end time regardless of how much alcohol is left.
Wholesale and case-discount math
At 12 cases of wine and 15 cases of beer, this order is large enough that most wine and spirits retailers have a case-discount tier for it, commonly 10 to 15 percent off shelf price once you clear a case-count minimum. Applied to the editorial retail estimate below, that would put the order closer to $2,093 to $3,312 instead of full retail. Ask specifically about a mixed-case or wedding-order discount when you place the order, since it isn't always advertised at the register, and pair it with free delivery, which most retailers extend automatically at this volume.
What a 300-guest bar costs
The list above sizes the bar; it doesn't price it. As an editorial estimate, the alcohol and mixers alone run about $8 to $12 per guest at typical US retail prices, which is roughly $2,462 to $3,680 for the whole 300-guest order before any case discount. That figure is our own construct, built from the exact bottle counts above times common retail price bands (wine around $12 to $18 a bottle, beer $24 to $34 a case, liquor $22 to $34 a liter). It excludes labor and it is not a quote.
Staffing at this size is 4 bartenders plus a barback at $35 to $75 an hour each, plus the $200 to $400 tip on top. For where your own market falls, see our cost-by-state and cost-by-city pages and the wedding bartender cost guide.

Frequently Asked Questions
How much alcohol do I need for 300 guests?
For a 4-hour open bar, 300 guests come to 1,200 drinks, and a 20 percent buffer rounds that up to 1,440 to buy. At the wine-leaning 25/50/25 mix that is about 144 bottles of wine (12 cases), 15 cases of beer, and 17 liters of liquor, plus mixers, 450 pounds of ice, and 900 cups. Staff 4 bartenders and a barback.
How do I split the bar into three stations for 300 guests?
Divide the full list by three and round each up so no station comes up short: about 48 bottles of wine, 5 cases of beer, 6 liters of liquor, 150 pounds of ice, and 300 cups per station. Spread the 4 bartenders across the three stations, roughly one to one, with the barback rotating to whichever line is running longest. Keep the drink menu identical at all three so guests never have a reason to cross the room.
How much alcohol for 300 guests at a 5 or 6 hour reception?
Every extra hour adds 300 drinks before the buffer at this size, which moves the order by a full case or more each step. A 5-hour bar for 300 guests needs about 1,800 drinks: roughly 180 bottles of wine, 19 cases of beer, and 21 liters of liquor. Six hours takes it to about 2,160 drinks, or 216 bottles of wine, 23 cases of beer, and 25 liters of liquor.
Can I get a wholesale or case discount buying alcohol for 300 guests?
Often, yes. At 12 cases of wine and 15 cases of beer, most wine and spirits retailers apply a case-discount tier, commonly in the 10 to 15 percent range off the shelf price, once an order crosses a case-count minimum. Applying that band to the editorial retail estimate below would put the 300-guest order closer to $2,093 to $3,312. Ask specifically for the mixed-case or wedding-order discount; some stores only extend it if you ask, and it's worth combining with free delivery once you're ordering at this volume.
How many bartenders and how much does a bar for 300 guests cost?
Plan on 4 bartenders plus a barback, the same staffing tier as 250 guests since the ratio rounds to the same headcount at 1 per 75. As an editorial estimate, the alcohol and mixers alone run about $8 to $12 per guest, or roughly $2,462 to $3,680 total, before labor and the 200 to 400 tip. Prices swing hard by region, so treat this as a planning range, not a quote.
