While taking inventory, and especially beer keg tracking, is probably not your favorite thing to do, you gotta do it often. As a bar owner or manager, you know that your inventory is your bar’s most valuable asset.It is an investment of your bar’s cash and every dollar spent on inventory is a dollar that you can’t put towards other costs. Buying things without keeping track of them is a huge risk. It can cause you to lose some cash and damage your bar's long-term profitability.
Why You Need a Draft Beer Inventory System
Bar inventory has become a lot more complicated with the rise of craft beer. That forces you and many other bars to increase your beer selections—especially on draft.
Some bars cater to craft beer drinkers by offering as many as 40 different selections on tap. Others simply choose to rotate their taps more often. It's common for bars to keep about half of their draft beers the same at all times. All while rotating the other half of their taps.
You might be one of the many bar operators asking yourself, "how much does a full keg weigh?" or “how many beers are in a half keg?” If so, here ya go!
How Do You Check a Keg?
There are essentially three ways to perform inventory on a beer keg. They are tenthing, using a keg scale, or using a keg checker. The best option for you will depend on your bar’s unique needs and your selection of draft beers. So don’t be afraid to try all of these out.
The most common method to measure beer kegs used by bars is tenthing. It involves dividing the keg into ten equal parts and estimating how much beer is left inside. If you get an odd number, simply round it up to the nearest tenth for your inventory. If you feel that your keg is more than 40% full but not quite half full, round it to 50%. Then label it as 0.5 on your inventory sheet. For full cans and bottles, count them as single units.
This method is extremely subjective and if you have two people take inventory, you might end up getting two different measurements. It may work for calculating liquor cost. But it's not accurate enough to provide you with enough detail properly evaluate your draft beer performance.
A better and more accurate way to perform inventory on your beer kegs is by using a keg scale. They can be purchased easily from most scale manufacturers as well as online. Make sure that you purchase a scale with a significant weight capacity. It should be able to accommodate a full ½ barrel keg at about 160 lbs. Each time you use your keg scale, test its accuracy first to avoid recording incorrect data later on.
When weighing your beer keg, you will also need to account for tare weight. While tare weight is not different for every brand, it varies based on your keg size. Simply weigh 3 to 4 kegs of a particular size and use this as the tare weight if you are unsure. There's one issue with using a keg scale to take inventory. Your staff needs to pick up kegs that are stacked on top of each other. That can be dangerous. Always train your bar staff on the correct procedure and safety cautions when doing this.
When it comes to beer keg tracking and draft beer inventory, keg checks are also a popular tool that many bars use. It has a torque wrench that is specially designed to measure the amount of beer left in a keg. However, we don’t recommend using this method if your bar carries a lot of smaller kegs, like the 1/4 barrel and 1/6 barrel kegs. You can use the keg scale option above for your smaller kegs. You won’t have to worry too much about the safety issue that we previously mentioned with smaller, lighter kegs.
