#1 Note your guest list
If you have a lot of kids, or non-drinkers, then there's really no point in having an open bar. Do the math - will bringing your own booze (even with the corkage fee) be a more wallet-friendly option instead?
#2 Skip the champagne toast
It's no longer a must-have for a champagne toast. After all, a toast should be more about the things that are said rather than the choice of drink. Instead, request that everyone's glasses are topped up just before the toast.
#3 Have a wedding lunch instead
We're seeing more couples opting for day time weddings instead. And why not? They're generally more affordable, give a laidback and fun feel, and reduces your alcohol expenditure since guests are inclined to drink more at night. Serve fun (and cost-saving) alternatives instead - punch, fruit-infused iced teas and juices.
#4 Limit the liquor
You can cut it out completely - it's your wedding after all, so don't feel compelled to serve more expensive liquor which takes a chunk out of your budget. Alternatively, serve liquor during cocktail hour, then switch to just beer and wine for dinner.
#5 Keep it to the bar
If you're having a signature cocktail or liquor served during cocktail hour, serve them at the bar instead of wait staff going around with trays. Most guests might take one, but not drink it which translates to wasted money. You can make a sign and display it at the bar so guests know they can request for one if they want it.
#6 Bring your own
Some wedding packages waive the corkage fee, and bringing your own booze can significantly lower the cost. Do take note though: There's a chance that you over- or underestimate the amount of alcohol needed, which either leaves you with several crates of wine left over or worse - falling short of beverages.
