The question every Connecticut couple eventually faces: how do we actually serve alcohol at the wedding? The terminology alone is confusing. Open bar. Cash bar. Consumption bar. Limited bar. Hosted bar. The words get thrown around by venues and caterers like everyone knows what they mean. Most couples do not — and that ambiguity costs money.
At Wonderbarz, we have run every variation at weddings across Greenwich, Westport, Stamford, and Fairfield. This guide breaks down the three real options — open bar, cash bar, and consumption bar — with actual Connecticut pricing, honest etiquette, and the hybrid approach most couples never hear about.
In This Guide
Open bar means the host pays for all drinks; guests pay nothing. Cash bar means guests pay for their own drinks. Consumption bar means the host pays only for what is actually poured, tracked per drink. Dry hire means you buy alcohol retail and hire professional bartenders separately — it is a staffing model, not a bar structure, but it applies to any of the three options above. In Connecticut, dry hire typically saves 30–50% on the beverage budget versus full-service catering.
Quick Comparison: The Three Options
| Option | Who Pays | Guest Experience | Average Cost (100 guests, 5 hrs) | Best For |
|---|---|---|---|---|
| Full Open Bar | Host (flat rate) | Seamless, generous | $4,500–$7,500 | Evening receptions, formal weddings |
| Cash Bar | Guests per drink | Friction, delays, poor etiquette | $1,500–$2,500* | Rarely appropriate for hosted events |
| Consumption Bar | Host (per drink) | Seamless, but with risk | $2,800–$6,000+ | Light-drinking crowds, tight budgets |
| Curated Limited Open Bar | Host (flat rate or retail) | Seamless, elegant, memorable | $1,200–$2,500 | Most Connecticut weddings |
*Cash bar “cost” reflects bartender and equipment fees only; guests pay for all alcohol separately. Total guest spending is not included.
Option 1: Full Open Bar
The standard expectation for evening wedding receptions. Guests walk up, order anything they want, and pay nothing. The host pays a flat per-person rate to the caterer or venue, and the bartenders handle the rest.
The upside: Zero friction at the bar. Guests feel taken care of. The host looks generous. No lines caused by payment transactions. Bartenders focus entirely on making drinks, not handling cash or cards.
The downside: Cost. In Connecticut, caterers typically charge $45–$75 per person for a 5-hour open bar. For 100 guests, that is $4,500–$7,500. The problem is not the concept — it is the markup. That same alcohol, bought retail, costs roughly $700–$1,400. The rest is labor, profit, and overhead baked into the caterer’s rate.
The Fix
Do not abandon the open bar concept. Abandon the caterer markup. Use a dry hire bartending team for professional staff and equipment, buy alcohol retail, and run your own open bar for 60–70% less. See our full dry hire cost breakdown for CT.
Option 2: Cash Bar
Guests pay for every drink they order. The host covers nothing except possibly the bartender’s base fee or equipment rental.
The upside: The host spends almost nothing on alcohol. For couples with severe budget constraints, this is mathematically the cheapest option.
The downside: Everything else. Cash bars create friction at the bar. Bartenders slow down to handle payments, ring up tabs, and make change. Guests who traveled, bought gifts, and dressed up feel nickel-and-dimed. In the Northeast, cash bars at hosted weddings are widely considered poor etiquette. We have seen guests leave reviews that mention the cash bar specifically — not the food, not the DJ, not the flowers. Just the bar.
There is also a hidden cost: the venue or caterer may charge a higher bartender fee for cash bars because they know gratuity will be lower and transaction handling is slower. Some Connecticut venues quietly discourage cash bars for this reason.
The Fix
If budget is the concern, skip the cash bar and move to a curated limited open bar instead. It costs the host slightly more but protects guest experience and your reputation. The difference is usually $500–$1,000 — less than the cost of one upgraded floral centerpiece.
Option 3: Consumption Bar
The host pays only for what guests actually drink. The venue tracks every pour — wine by the bottle, beer by the unit, cocktails by the recipe — and bills the couple afterward.
The upside: You only pay for what is consumed. If your crowd drinks lightly — older demographics, daytime events, or conservative family cultures — a consumption bar can cost 30–40% less than a flat-rate open bar.
The downside: Risk and uncertainty. A lively crowd, warm weather, or a late-night crowd can push consumption well above the flat-rate price. Plus, most caterers add 20–25% service fees and sales tax to the consumption total, which erodes savings. One 150-guest wedding in Norwalk ended with a consumption bill of $6,200 — $800 more than the flat-rate open bar quote they had declined.
Consumption bars also require trust. You are relying on the venue to track honestly. Few couples audit the final bill against actual guest behavior.
The Fix
If you choose consumption, negotiate a spending cap. The bar switches to cash (or closes) once the cap is reached. This limits downside while preserving the “pay for what you use” structure. Better yet, use dry hire and buy retail — you control the inventory, and unopened bottles go back to the store.
Wonderbarz Pro Tip
Most caterers will not offer dry hire as an option unless you ask directly. Their business model depends on the markup. When you ask “Can we provide our own alcohol and hire outside bartenders?” you are cutting into their margin. Ask anyway. Connecticut law permits BYO alcohol at licensed private events, and many venues — especially DIY estates — encourage it.
The Better Way: Curated Limited Open Bar
This is the option most couples never hear about because it does not have a catchy name. It is an open bar with a thoughtfully limited selection. Not a restricted bar. A curated one.
The structure is simple: 2–3 signature cocktails, 4–5 spirits, wine (red and white), beer, and champagne or prosecco for toasts. That is it. No back-bar of 20 bottles. no obscure liqueurs. no top-shelf tequila that two guests might order.
Why it works: Guests have options. A beer drinker finds beer. A wine drinker finds wine. Someone who wants a cocktail gets a beautifully designed signature drink with a name tied to your wedding. But the host buys 60% less inventory, wastes almost nothing, and keeps the bartenders moving fast.
At a Greenwich estate wedding last fall, the couple chose a curated open bar: two signature cocktails (a spritz and an old fashioned), Pinot Grigio, Cabernet, two local craft beers, and prosecco. Total alcohol cost: $980 retail. Bartender fees for 3 staff over 5 hours: $720. Total bar spend: $1,700 for 140 guests. The caterer’s open bar quote for the same event: $8,750.
The Fix
Work with your bartending team to design 2–3 signature cocktails that are memorable but operationally simple. A drink that requires muddling, shaking, and garnishing will slow the line. A drink that pours, stirs, and serves takes 30 seconds. The right signature cocktail is both Instagram-worthy and bartender-friendly.
Real Costs for a 100-Guest Connecticut Wedding
Here are actual numbers from Connecticut events we have staffed. These assume a 5-hour reception (cocktail hour + 4 hours).
| Approach | Alcohol Cost | Staffing / Equipment | Total |
|---|---|---|---|
| Caterer full open bar | Included in markup | Included | $4,500–$7,500 |
| Caterer consumption bar | $2,200–$4,500 | $600–$1,200 + fees | $2,800–$6,000+ |
| Dry hire curated open bar | $700–$1,400 retail | $500–$850 | $1,200–$2,250 |
| Dry hire full open bar | $1,000–$1,800 retail | $500–$850 | $1,500–$2,650 |
Dry hire staffing costs include TIPS-certified bartenders, bar equipment, glassware, ice transport, and setup. Alcohol is purchased separately at Connecticut retail prices. Unopened bottles can be returned to most retailers.
How to Choose: A Simple Decision Framework
You do not need a spreadsheet. You need three answers:
1. What time of day is the reception?
Daytime and brunch weddings have lighter drinking. A consumption bar or limited open bar makes sense. Evening receptions with dancing expect a full open bar. Guests who paid for a babysitter and an Uber to a Saturday night wedding in Stamford do not want to pull out their wallet at the bar.
2. Who is coming?
A 70-person dinner with mostly family over 50 drinks differently than a 200-person party with 80 college friends. Know your crowd. If 40% of your guest list does not drink, do not buy alcohol for 100% of them.
3. What is the real budget ceiling?
Not the number you hope for — the number that, if exceeded, causes stress. If that number is $2,500, a curated dry hire open bar is your answer. If it is $7,000, you can comfortably do a full open bar through a caterer or save money with dry hire.
Our Recommendation
For 90% of Connecticut weddings, the curated limited open bar with dry hire staffing is the right answer. It delivers the guest experience of a full open bar at roughly 35% of the caterer price. Use our alcohol calculator to lock in exact bottle counts, then use our bartender ratio guide to confirm staffing.
