Keg Kicked Mid-Shift: A 4-Job Routine for Busy Nights
When a keg kicks mid-shift, bar staff run 4 jobs in a set order: call the kick by tap number, offer the guest a sub picked before service, fix the board line, and swap the keg during the rush only if a cold backup and a free pair of hands are ready.
Below are the call, the sub map, the board fix with the math on a slow one, the swap decision, a solo bartender version and a kick card to print.
What are the 4 jobs when a keg kicks mid-shift?
The 4 jobs are calling the kick, saving the guest, fixing the board and swapping the keg, and each one needs an owner before doors open. A full crew splits them up. On a skeleton crew, 1 person works through them in order.
| Job | Who owns it | Done when |
|---|---|---|
| 1. Call it | The bartender who pulled the foam | Someone answers "heard" |
| 2. Save the guest | The same bartender | The guest has a full pour of the sub, or a taste and a no |
| 3. Fix the board | The shift's board owner | The line is marked kicked, taken down or replaced |
| 4. Swap the keg, or decide not to | The barback, or the swapper named at pre-shift | The new keg pours clear and the handle tag is off |
How should the bartender call a kicked keg?
The bartender who hits foam calls it by tap number, loud enough for the whole bar to hear: "Tap 1's kicked." The number is on the handle and on the board, so nobody has to catch a beer name in a loud room. Someone answers ("Heard, tap 1") so the caller knows it landed.
On a big wall, the call only works if the handles and the board use the same numbers. Numbering the handles on a 30 to 40 tap wall covers how to set that up.
Servers need the call too. They take orders at tables off the board and walk them to the service well, so a kick that never reaches them turns into tickets for a beer that's gone. Whoever stands nearest the well tells them, or it goes on the server board.
Then 2 quick things at the tap:
- Tag the handle. A clip-on tag, a rubber band or the handle turned backward all work, as long as the house uses 1 signal and everyone reads it the same way. The tag keeps the next bartender from pulling foam into a clean glass.
- Dump the foam. Pour out the half-foam pint and start the guest fresh on something else.
What should the bartender offer the guest instead?
The bartender offers 1 sub, chosen before doors open and written on a sub map: nearest style, similar strength, same price or lower. The worst time to pick a substitute is with the guest standing at the rail.
Here is a sub map for part of a 16 tap list. Tape it where every bartender can see it, next to the kick card further down.
| Tap | If this kicks | Offer tap | Sub | Price check |
|---|---|---|---|---|
| 1 | Helles lager, 4.9%, 16 oz $7 | 2 | Pilsner, 5.0%, 16 oz $7 | Same |
| 2 | Pilsner, 5.0%, 16 oz $7 | 1 | Helles lager, 4.9%, 16 oz $7 | Same |
| 5 | Hazy IPA, 6.5%, 16 oz $8 | 6 | West Coast IPA, 6.8%, 16 oz $8 | Same |
| 6 | West Coast IPA, 6.8%, 16 oz $8 | 5 | Hazy IPA, 6.5%, 16 oz $8 | Same |
| 9 | Raspberry sour, 5.5%, 16 oz $9 | 8 | Gose, 4.5%, 16 oz $8 | $1 lower |
| 10 | Porter, 5.8%, 16 oz $7 | 11 | Oatmeal stout, 6.2%, 16 oz $7 | Same |
| 16 | Dry cider, 6.2%, 12 oz $8 | 15 | Cherry cider, 5.5%, 12 oz $8 | Same |
Recheck the map after every kick. A sub that is running low won't cover the next one, and if tap 2 kicks while tap 1 is already down, the map needs a third choice for that pair.
The line to say is short. Say it's gone, name 1 beer, say why it's close, and offer a taste:
"That one just kicked, sorry. Closest thing we have is the pilsner on tap 2, another crisp lager, same price. Want a taste?"
Give the guest 1 option and skip the tour of the board. A taster pour often settles the choice faster than a description does.
Settle the money rules before the shift
Nobody should be working out prices in the rush, so decide these at pre-shift:
- When the sub costs more than the kicked beer, the house either honors the kicked beer's price for that pour or charges the sub's price. Either rule works as long as nobody guesses.
- When the guest already paid or the beer is on a tab, re-ring it or leave it, per your rule.
- When the guest got a half pour before the kick, they get a full pour of the sub. Don't top off a half pint of one beer with another.
How fast does the board need to change after a kick?
The board needs to change before the next order comes off it, which in a rush means at the first pause instead of the next lull. Make that 1 named person's job each shift, the board owner, and put the name on the shift handoff card so nobody assumes someone else has it.
The board owner has 2 choices:
- The replacement goes on now. Change the whole line: maker, beer, style, ABV, pours and prices. Pull the prices from your cost per ounce sheet instead of from memory.
- The replacement isn't ready. Mark the line kicked or take it down. Don't leave it up unmarked.
The math on a slow fix
The example below is 1 fast seller on a busy night. Swap in your own pace and price.
Inputs:
- The kicked beer was selling 1 order every 2 minutes.
- A 16 oz pour is $8.
- Every order placed off a wrong line is a guest who hears "we're out" and then gets the sub pitch.
| How the line gets fixed | Minutes the line is wrong | Orders off the wrong line | Order value riding on the sub pitch |
|---|---|---|---|
| Chalk rewrite at the next lull | 20 | 20 / 2 = 10 | 10 x $8 = $80 |
| Clip-on KICKED card at the first pause | 4 | 4 / 2 = 2 | 2 x $8 = $16 |
| Digital line changed at the first pause, plus up to 0.5 minutes for screens to check | 4.5 | 4.5 / 2 = 2.25 | 2.25 x $8 = $18 |
In all 3 rows, the minutes before anyone makes the first fix drive the count. On a chalkboard mounted high, the full rewrite means a ladder in a full room, so a clip-on card over the line holds until the lull. On a digital board, the first fix and the full fix are the same edit.
Kicked note or take it down?
On a long list in a packed room, taking the line down keeps the list shorter and faster to read. On a short list, a kicked line tells regulars the beer sold through and sets up whatever goes on next, which is the job of an on deck section. Pick 1 and do it the same way every shift.
On a TapDisplay board, the board owner marks the beer kicked from a phone, tablet or computer behind the bar. The line stays on the list, struck through, with a KICKED label. The word comes from the business type: keg menus such as a brewery, bar or cidery say KICKED, and coffee, wine or cocktail menus say SOLD OUT.
Each connected screen checks for changes every 30 seconds, so the edit shows on every connected screen within about 30 seconds. Staff accounts can make the change, the activity log records who did it, and undo puts it back if someone marks the wrong tap.
When the replacement goes on, start typing its name and pick a match from the catalog. The catalog fills in the brewery, style and ABV you have not entered yet, and you add the pour prices.
Should you swap the keg now or after the rush?
Swap mid-rush only when waiting costs more than taking a person off the rail, and only with a keg that is already cold. The Brewers Association's Draught Beer Quality Manual says every keg must be at or below 38°F when served, and that even a few degrees above 38°F can create pouring problems, especially excessive foaming.
The same manual's chill table gives a keg at 44°F, which can still feel cold to the hand, 18 hours to reach 38°F. A keg at 50°F needs 25 hours. A backup that came in on today's delivery is not a mid-rush backup.
| Situation | Swap now? |
|---|---|
| Second keg of the same beer, in the cooler since at least yesterday | Yes, if it's a fast seller |
| A different beer going on that tap | Usually wait for a lull |
| Backup keg came in today or sat out warm | No. It will pour foam. Leave the line down |
| 1 person behind the bar | No. Swap after the rush |
| Tonight's top seller, cold keg ready, someone free | Yes |
The barback swaps if you have one. If you don't, send the bartender with the fewest open tabs instead of the one who called the kick. The Brewers Association manual notes a full keg typically weighs 165 lb and recommends buddy-lifting or a mechanical lift, so plan the swap for 2 people or a lifting aid.
Getting the backups cold the day before a big night is covered in game night keg prep.
The swap, step by step
- Check the label on the new keg against what's on deck for that tap. A wrong keg on the line means the board is wrong twice.
- Pull the coupler off the empty and rinse the coupler face.
- Tap the new keg.
- Pour off foam into a pitcher until it runs clear.
- Pour a small taste and check it. The manual's pre-service tower check is to pour 1 to 3 fl oz and confirm the tap marker matches the beer in the line. You're checking for the right beer, nothing off and nothing warm.
- Take the tag off the handle.
- Tell the board owner it's live, then call it out loud: "Tap 1's back," plus the beer's name if it changed.
- Mark the empty shell and move it out of the walk-in path.
If your long-draw system has foam on beer detectors (FOBs), the manual explains that an FOB stops beer flowing through the line once the keg empties, which keeps the line packed and cuts the beer lost at a keg change. Bring that line back with your system's own steps once the new keg is on.
What if you're the only bartender?
Alone behind the bar, the guest in front of you comes before the board, and the board comes before the keg. In order:
- Dump the foam and tag the handle.
- Offer the sub and finish that guest's round.
- Fix the board at the first pause.
- Swap last, or after the rush.
On a chalkboard, step 3 is the clip-on card and the rewrite waits for a lull. On a digital board, step 3 is 1 edit from behind the bar. Either way, a solo bartender doesn't leave the rail for the walk-in until the rush breaks.
What goes on a printed kick card?
A kick card holds the whole routine plus the 3 blanks that change every shift: the price rule, the board owner and the swapper. Print it, fill in the blanks at pre-shift, and tape it next to the sub map.
KICK CARD
1. Call it: "Tap [number]'s kicked." Wait for "heard."
2. Tag the handle. Dump the foam.
3. Tell the servers.
4. Offer the sub from the sub map. Price rule tonight: ______
5. Board owner this shift: ______ Fix the line at the first pause.
6. Swap now only if: same beer or top seller, keg cold since yesterday, someone free.
7. Swapper this shift: ______
8. When it's back: "Tap [number]'s back, [beer]."
9. Write the kick on the shift handoff card.
After the rush, check every other place the beer is listed. A kicked beer that still shows on your website brings guests in for something you can't pour, and keeping the website tap list current covers that check. Marking a keg low before it kicks, and deciding whether guests see it, has its own post: keg levels on the board.
The bottom line
A kick mid-shift costs 1 foamy pour when the call, the sub, the board fix and the swap each have an owner before doors open. Serve the guest first, fix the board at the first pause, and leave the keg for last. Swap during the rush only with a keg that has been cold since yesterday and a free pair of hands.
Questions operators ask next
Why does a new keg pour mostly foam right after a swap?
A keg warmer than 38°F is a likely cause. The Brewers Association's Draught Beer Quality Manual says every keg must be at or below 38°F when served, and that even a few degrees above that can cause excessive foaming. Its chill table gives a 44°F keg 18 hours to reach 38°F, so a keg that came in on today's delivery usually belongs on tomorrow's list.
Can linking kegs keep a fast seller from kicking mid-rush?
Linking can help on a beer you empty fast. The Brewers Association's manual describes chaining 2 or 3 kegs of the same beer so all of them empty before the beer stops flowing, and says a series fits only accounts that turn kegs rapidly. It also says to empty the whole series regularly, with every 7 days a common practice at breweries, so old beer does not sit in the chain.
How long before a kicked line shows on every TapDisplay screen?
About 30 seconds. Each connected screen checks for changes every 30 seconds, so once the board owner marks a beer kicked from a phone, tablet or computer, the struck-through line with its KICKED label shows on every connected screen within about 30 seconds. The slower part is usually the minutes before anyone makes the change, which is why the board owner fixes the line at the first pause.
Does the board owner need to be a manager to mark a beer kicked?
No. In TapDisplay, the staff role can edit the menu, including marking a beer kicked, typing in keg levels and changing prices, so a bartender can own the board for the shift. Managers and owners also run the screens and the look. An activity log records who changed what, and undo reverses a change if someone marks the wrong tap.
What should the next shift hear about a kick?
Write each kick on the handoff with the tap number, the time, whether the keg was swapped, and what is on that line now. The next shift then knows which backups are already used up and which lines may need a new beer before doors open. Note any sub that ran low too, so the opener can update the sub map before the first rush.
