Every bar you work in will teach you something new. No bartender knows it all—and anyone who tells you they do probably hasn't been behind a bar long enough.

Here are some of those little things you pick up along the way.

1. When in Doubt, Salt Half

Can't remember whether the guest wanted salt on their Margarita? Rim half the glass. Now they can drink from the salted side or the unsalted side.

Congratulations. You just turned forgetfulness into customer choice.

2. “Lemonade” May Not Mean Lemonade

When a guest with a British accent orders lemonade, they may mean a carbonated lemon-lime drink similar to Sprite or 7UP rather than American-style still lemonade.

Don't assume—double-check. It's much easier than remaking the drink.

3. “Whisky” Can Mean Different Things

A European guest ordering “whisky” may expect Scotch whisky, depending on where they're from and what they're used to drinking.

Again, simply ask. Ten seconds of clarification beats one unwanted whiskey.

4. Learn the Head Game

Beer-drinking customs vary worldwide, and many European beer styles are traditionally served with a larger, more deliberate head than the typical American draft. If your European guest looks disappointed by that perfectly flat-to-the-rim beer, you may have been a little too generous.

5. Know About Spotters

Some establishments hire spotters, shoppers, or mystery shoppers to pose as ordinary guests and report what they observe—service, cash handling, alcohol procedures, cleanliness, comps, and more. The point is, you usually won't know who they are.

So treat every guest as though they're a shopper. It's also conveniently the same way you should treat guests anyway.

6. Speed Pourers Are About Speed

Bottle pourers belong on frequently used bottles because they're for speed, consistency, and control. There's a reason they're called speed pourers and not Let's Take Our Sweet Time Pourers.

7. Rotate Your Beer

When stocking a beer cooler, develop a simple rotation system. Move the existing beer to one side and place the new beer on the other, making sure the older product gets used first. First in, first out. Your beer cooler should have better organizational skills than your junk drawer at home.

8. All Cognac Is Brandy, but Not All Brandy Is Cognac

Cognac is a type of brandy produced in the Cognac region of France under specific production requirements.

Brandy is the larger family and can be produced in many places and from various fermented fruits.

Think of it this way: Cognac has an address. Brandy has relatives everywhere.

9. Understand Sour Mash

“Sour mash” doesn't mean the whiskey is sour. It refers to a production method in which material from a previous fermentation/distillation cycle is incorporated into the next batch to help maintain consistency—somewhat like maintaining a sourdough starter.

And Jack Daniel's doesn't taste distinctive simply because it's sour mash; many American whiskeys use the process. Jack Daniel's is also known for the Lincoln County Process, in which the new spirit is mellowed through sugar maple charcoal (burnt wood from a sugar maple tree) before barreling.

So no, “sour mash” isn't a flavor. Please don't go looking for the sweet mash aisle.

10. Champagne Has an Address Too

True Champagne comes from the Champagne region of France and must meet its production rules. Bubbly wine made elsewhere is generally called sparkling wine or another regionally protected name.

Champagne isn't just being fancy. It has paperwork.

11. Know Your Tequila

Tequila is produced under Mexican regulations in designated regions and must be made from blue Weber agave. Products labeled simply “tequila” may contain at least 51% sugars from blue agave, while 100% agave tequila must derive all fermentable sugars from blue agave.

Mezcal is a separate Mexican agave-spirit category that can be produced from numerous permitted agave varieties.

In other words, tequila and mezcal are relatives, not twins.

12. Say “Sold Out,” Not “We're Out”

When you don't have something a guest requests, try: “I'm sorry, we're sold out of that.”

“We're out” can sound like somebody forgot to order it. “Sold out” makes it sound so popular that everybody else beat them to it. Same empty shelf. Much better public relations.

13. Bourbon Doesn't Have to Come From Kentucky

Bourbon can legally be produced anywhere in the United States as long as it meets federal Bourbon standards.

But if the label calls it Kentucky Bourbon, it must qualify for that geographic claim.

Kentucky may be Bourbon's most famous home, but it doesn't own the whole neighborhood.

14. Only Time Sobers You Up

Coffee doesn't sober someone up. Food doesn't sober someone up. A cold shower doesn't sober someone up.

Time does.

Coffee gives you a wide-awake drunk, food gives you a full drunk, and a shower gives you a wet drunk.

15. Don't Redesign the Bar on Day One

When you start at a new bar, resist the temptation to immediately rearrange things or explain how everything could be done better. And avoid: “Well, at my last bar, we did it this way…” Nobody cares.

Observe. Learn their system. Give yourself several weeks before suggesting changes.

Your old bar may have done it differently, but this isn't your old bar. That's why it's called your old bar.

16. A Classic Martini Starts With Gin

Traditionally, a Martini is made with gin and dry vermouth. But modern guests frequently use “Martini” to mean a vodka Martini, so clarify rather than lecture.

A nice approach is: “Absolutely. Do you have a favorite gin, or would you prefer vodka?” You get the information you need without turning happy hour into

cocktail-history class.

17. If You've Got Time to Lean…

When business slows down, don't just stand around. There's always something to wipe, wash, stock, polish, organize, prep, or refill. If you truly can't find anything that needs attention behind a bar, look again.

18. Bartender Burnout Is Real

Bartending is physically and mentally demanding, especially when you've been dealing with the public for hours, days, weeks, and years. You'll recognize burnout when little things suddenly start irritating you and your patience gets shorter with guests and coworkers.

Take some time off. Recharge. Go somewhere and let somebody else wait on you for a change. And whatever you do, don't tell their bartender how you would have made the drink.

19. Pick Up a Bottle Once

When making several drinks, try to pick up each spirit or mixer only once.

If four drinks need vodka, pour the vodka into all four before putting the bottle down.

Every unnecessary movement costs time. Multiply that by hundreds of drinks a night and suddenly you've completed a full-body workout nobody asked for.

20. “Dry” Means Less Vermouth

When someone orders a dry Martini, they generally want less dry vermouth. Extra dry usually means even less. Preferences vary considerably, though, so when in doubt, ask. Some bartenders joke about merely waving the vermouth bottle over the glass.

At a certain point, you're basically just letting the Martini know vermouth exists.

21. Don't Make a Spill More Embarrassing

When a guest spills something, they're usually embarrassed enough already. Don't sigh, roll your eyes, or act irritated. Smile and say: “It's okay. It happens.” Watch their entire face relax. You've just turned an embarrassing moment into good hospitality—and yes, sometimes good hospitality mysteriously appears later on the tip line.

22. Acknowledge Guests Even When You're Slammed

If you can't get to someone immediately, acknowledge them. Eye contact, a smile, a nod, or “I'll be right with you” tells them they've been seen. People are generally much more patient when they know they're not invisible.

23. When You're Slammed, Just Keep Going

You can only move so fast. If you're stocked and organized, keep working, keep smiling, and give the guest in front of you your attention.

Don't let the ten people waiting make you give lousy service to the one person you're serving. Remember: a busy bar is a good problem to have.

Without those people waiting for drinks, you wouldn't have a job—or tips.

24. Treat Bottles Like Money

Hold liquor bottles firmly and handle them carefully. Depending on the product and your establishment's pricing, a single bottle can represent hundreds of dollars in potential sales. So when you're holding a bottle, you're essentially holding money.

Except dropping twenty-dollar bills doesn't usually require a mop.

25. Broken Glass Near Ice? Burn the Ice

You will spill something. You will break something. It’s part of bartending.

But if glass breaks anywhere near an ice well, stop using that ice immediately. Tiny shards can travel farther than you think, and one nearly invisible sliver is all it takes to seriously injure a guest.

​

If you’re working with other bartenders, make it impossible for anyone to accidentally scoop from the contaminated well. Lay a bar towel across the ice and pour a big red X over it with grenadine. Now everybody knows: DO NOT USE THIS ICE.

​

Next, get a clean ice bin filled with fresh ice so you and the other bartenders can keep making drinks while you deal with the contaminated well.

Then you—or hopefully your wonderful barback—can start burning the ice. Get a bin of hot water, melt and remove all the ice, thoroughly clean the well according to your establishment’s procedure, and refill it with fresh ice.

​

Don’t try to inspect the ice and decide whether you can see any glass. You can’t see what you can’t see. When in doubt, burn it. Yes, it’s a pain, especially when you’re slammed. But the inconvenience doesn’t matter. The most important thing is making absolutely sure a guest never ends up with a shard of glass in their drink. No cocktail, no rush, and no amount of wasted ice is worth risking someone getting hurt.

​

Besides, burning an ice well in the middle of a Saturday-night rush is still considerably less inconvenient than serving a guest a Martini with a glass garnish nobody ordered.

26. Don't Let Guests Pick Up Broken Glass

When a guest breaks a glass, their first instinct is often to help. Immediately tell them:

“Don't touch it—I've got it.” Clean up the large pieces safely with the proper tools. For tiny fragments on an appropriate surface, a damp disposable towel can help collect remnants after you remove the larger pieces.

 

Follow your establishment's broken-glass procedure and dispose of everything safely. Most bars do not throw broken glass in the trash. There should be a designated bucket or box for that purpose. Guests came for drinks. They don't need to leave with stitches as a souvenir.

27. Ask Before Coming Behind the Bar

Most bartenders are protective of their workspace, and for good reason. It's tight, fast-moving, slippery, and full of people carrying bottles, glassware, and hot liquids.

If you're a server or other employee who doesn't normally work behind the bar, ask before entering whenever possible. Behind the bar is basically a bartender's kitchen, office, cash register, and dance floor squeezed into four feet of space.

28. Every Bar Has a Trade-Off

Every bar has good things and irritating things. At a hotel, maybe the kitchen is three zip codes away—but a cleaning crew washes your mats and mops your floor.

At a restaurant, maybe you make killer money—but you're constantly transferring checks when bar guests get seated at tables. Every bar has something.

The perfect bar exists in approximately the same location as the perfect manager, the perfect schedule, and the guest who says, “Surprise me,” then loves the first drink you make.

29. Guests Can Hear You

Have you ever sat somewhere while employees carried on a personal conversation as though you weren't there? Don't do that. Guests don't need to hear about your dating life, coworker drama, horrible manager, schedule complaints, hangover, landlord, or what Ashley supposedly said about Brittany in the walk-in. The bar has guests, not invisibility cloaks.

30. Be Able to Do the Job

Every bartender should be prepared to perform the physical duties required by the position—changing kegs when trained and able, moving appropriate cases and supplies, hauling trash, stocking, cleaning, and doing the less glamorous jobs.

​

Work safely, use proper lifting techniques, ask for help when an item requires two people, and follow workplace procedures. Once your team knows you're willing and able to share the workload, it's much easier to trade responsibilities: I'll count the money and finish the cash-out while you handle the heavy restocking.

That's teamwork. Nobody gets hired exclusively for the glamorous lime-wedge department.

31. Don't Immediately Dump a Mistake

If you accidentally make the wrong drink, follow your establishment's policy. Some bars may allow you to temporarily hold a freshly made, uncontaminated drink for an identical order; others require you to discard it and record it immediately.

​

Never serve something that has been sitting too long or hasn't been handled safely.

If it can't be used, put it on the spill/waste sheet as required. Mistakes happen. That's why spill sheets exist—and why bartenders occasionally whisper bad words under their breath.

32. Don't Put the Bar Keys in Your Pocket

Make it a habit never to put the bar keys in your pocket. Use the establishment's designated key location or, if permitted, a secure clip or hook. Why? Because anything you put in your pocket at work has an excellent chance of going home with you. And nothing says “good morning” quite like realizing at 7:00 a.m. that the keys to the entire bar are sitting on your nightstand.

33. Let Things Breathe When Drying

When you turn washed equipment or containers upside down to air-dry, make sure they're positioned so air can circulate underneath and water can drain properly.

Don't seal a wet container flat against a surface and assume you've accomplished something. You haven't dried it. You've built a tiny indoor swimming pool.
