Bar training that keeps every drink on spec

A new bartender picks up glass handling, ice and the register by watching for a few shifts. House specsA drink's exact recipe: each ingredient and how much of it. are different. A new bartender who learns the Paper Plane from a colleague learns that colleague's version. And because bar staff change often, you will train often. So write your training down once, in four parts: levels, a four-week plan, a spec test, and a routine that keeps every drink on spec.

Training levels and sign-offs

Bar training must cover these skills:

• make every drink on your menu to spec
• work a station through the busiest hour
• open and close a station
• serve alcohol responsibly

Levels put these skills in order. Each level gives the new bartender a clear next step and tells you who can work which station.

We recommend four levels. Adapt them to your bar. Each level ends with a sign-off by the head bartender or the bar manager. They sign it on the Levels and sign-off sheet of the free training manual, a spreadsheet you can download at the end of this guide.

Most new bartenders are working toward level 3. Level 4 is for experienced team members who are ready to train others, and doesn't need to be part of their first four weeks.

When someone doesn't pass a sign-off, write down what they missed and what to practice before the next try.

A four-week bar training program

Say your menu has 13 cocktails and you sell 300 cocktails a night. Your six best sellers make up 210 of them: 210 ÷ 300 = 70%. A new bartender who learns those six in week one already knows the recipes for 7 in every 10 cocktails you sell. So teach the best sellers first. In this example, they are the Espresso Martini, Negroni, Daiquiri, Paper Plane, Old Fashioned and Aperol Spritz. The other 7 drinks come in week two.

If your menu is longer, give weeks two and three more time. Some new hires already know part of week one, so they need less time on it. To find out how much they know before you hire, ask candidates to talk you through a spec in the interview.

For an experienced bartender, a four-week training plan is a useful starting point. Adjust it to their experience and your menu, and let them work independently once they've demonstrated the skills your bar requires.

Responsible service certification is separate from this plan, and the law sets its deadline. In California, servers and managers must be certified within 60 days of starting work, and the certificate is valid for three years.

How to run a spec test

A spec test has two parts. The written part checks that a bartender knows each drink on your menu. The practical part checks that they make it the same way twice, in front of the head bartender.

For the written part, list the drinks by name. The new bartender writes down the glass, ice, method, garnish, and every ingredient with its amount. For the Paper Plane, the right answer is ¾ oz (22.5 ml) each of bourbon, Aperol, Amaro Nonino and lemon juice. Shake with ice, double strain into a chilled coupe, no garnish. Mark each part right or wrong. A drink passes only when every part is right, because one wrong amount makes a different drink.

Run the practical part in a quiet hour. Watch how they use the jiggerA small measuring cup for pouring exact amounts of spirits and other ingredients., how they shake or stir, and how they strain. Taste the drink next to one the head bartender made.

Then ask them to make a second Paper Plane, pouring each ingredient into a measuring cylinder. Do this before any ice goes in, because melting ice adds volume. The four 22.5 ml measures should total about 90 ml before dilution: 3 oz, counting 1 oz as 30 ml. If the cylinder reads 97.5 ml, check the individual pours to find the extra ¼ oz (7.5 ml). The total tells you something is wrong, but not which ingredient was over-poured.

Don't rely on the total alone. A bartender can pour too much of one ingredient and too little of another, and still finish at 90 ml. So read the cylinder after each pour: 22.5, 45, 67.5 and 90 ml.

Why house drinks drift off spec

Spec drift is when a house drink slowly changes as it passes from one bartender to the next. Nobody decides to change it. One bartender pours a little too much bourbon into the Paper Plane, without a jigger. The next bartender learns the drink from them. A year later, you sell a different drink at a different cost.

Research has found substantial differences in the amount of alcohol served in drinks at bars and restaurants. A 2008 Northern California study measured drinks from 80 establishments and found that mixed spirits drinks contained more alcohol on average than a standard drink. That doesn't necessarily mean the bartenders were pouring above their house specs, but it shows why you shouldn't assume every bar serves the same amount.

In your own bar, the way to check accuracy is to compare what bartenders pour with your spec. Train with a jigger on every pour from the first shift, run occasional pour tests and taste drinks against the house standard.

Drift also costs money. Say the Paper Plane sells for $14 and its ingredients cost $3.42. Its pour cost is 3.42 ÷ 14 = about 24%. The bourbon costs $30 for a 750 ml bottle, so 30 ÷ 750 = 4 cents a ml. An extra ¼ oz (7.5 ml) of bourbon costs 7.5 × $0.04 = $0.30.

With that extra bourbon, the drink costs $3.42 + $0.30 = $3.72, and its pour costThe cost of a drink's ingredients divided by its menu price, as a percentage. is 3.72 ÷ 14 = about 27%. At 30 Paper Planes a night for 30 nights, you sell 900 a month. That is 900 × $0.30 = $270 a month, on one drink. To see how far each bartender's pours have moved, measure them in a pour test.

Log every change to a spec, with the date and who made it, on the manual's Change log sheet. Then everyone trains from the same version.

A training calendar that keeps going

Training does not stop at the sign-off. This calendar keeps the whole team on spec.

Responsible service training is not on this calendar, because the law sets when it happens. Check the rules where your bar is. Keep a separate record of each team member's responsible service certificate and its renewal date. House spec tests and legal certification serve different purposes, so track both.

Free bartender training manual

The manual is a spreadsheet, not a long document, because specs change every season. A spreadsheet is easier to keep current, to print for the bar and to score the spec test in. It has ten sheets.

Replace the sample drinks with your own, and print the spec test for each new bartender. For shift routines, start from the free opening and closing checklist.
