Running a craft beer bottle shop's fridge rotation
A craft beer fridge is a slow moving cold store with a glass door. Run it on dates, temperature and a weekly routine and your customers taste the beer the brewer made. Run it on instinct and they taste cardboard.
Fresh beer is a stock control problem
Most craft beer that disappoints a customer was fine when it left the brewery. It went stale on the way, often in the last fortnight of its life, sitting warm in a stockroom or under a bright light. A bottle shop cannot change the recipe. It can control time, temperature and light, which are the three things that age packaged beer.
Hop aroma fades first. A hazy IPA that smelled of mango and pine at four weeks can smell of onion and paper at four months. Malt forward lagers and dark beers hold up longer, but none of them improve in a shop fridge. The job is to sell each can or bottle while it still tastes the way the label promises.
Rotate by packaging date, not by arrival
First in, first out is the rule every grocer knows. For beer it needs one change: rotate by the date the beer was packaged, not the date it reached you. Two cases of the same IPA can arrive in the same week three months apart in age.
Check the can or bottle for a packaging date or a best before date when stock comes in. Write the packaging date on the outer case in thick marker. If a brewery prints only a best before date, ask how long their shelf life is so you can work back to the packaging date. Many craft breweries give hop forward beers a shorter shelf life than their lagers. Some tell retailers to sell their IPAs within about three months of canning.
Load the fridge from the back. New stock goes behind, older stock comes forward. It takes a little longer than dropping cans in the front gap, but it is the only way older beer sells first.
Keep it cold from delivery to door
A common rule of thumb is that every 10 °C rise in storage temperature roughly doubles the rate at which beer stales. In an Indian summer the stockroom can sit above 35 °C. A week back there can age an IPA more than a month in a cold room would.
- Set display fridges to about 3 to 5 °C and check them with a separate thermometer, because the dial on the door is often wrong.
- Keep backstock in a cold room or a second fridge, not in cartons by the counter.
- Put fridges on an inverter or generator circuit where power cuts are common. A fridge that warms up and cools down every afternoon is cycling the beer it holds.
- Leave a gap of a few centimetres behind and above the stock so cold air can circulate. An overfilled fridge has warm pockets near the door.
Ask your distributor how the beer travelled. Craft beer that sat in an unrefrigerated truck for two days has already lost some of its life before you rotate it.
Light ruins beer faster than heat
Hop compounds break down under light and form a sulphur compound that smells like a skunk, which is why brewers call the fault lightstruck. Clear and green glass let the damaging wavelengths through within minutes in bright light. Brown glass blocks most of it. Cans block all of it.
Position clear and green bottles in the darker lower shelves or keep them in their cartons. Fit LED fridge lighting rather than old fluorescent tubes. Keep the fridge out of direct sun from the shop window. Our guide to beer shelf life explains the other staling reactions in more detail.
A weekly routine that takes 30 minutes
Rotation fails when it depends on one careful person remembering. Make it a fixed weekly job on a quiet morning:
- Read every fridge thermometer and write the reading in a log.
- Pull each line forward and check the dates on the front row.
- Move any beer within a month of its best before date to a clearly marked spot near the till.
- Count slow lines and note which ones have not sold a case in four weeks.
- Clean the glass and shelves, because a sticky fridge looks like an old one.
Keep the log for a few months. It will show you which beers you over order and which fridge runs warm in the afternoon.
What to do with beer that is getting old
Old stock is a buying mistake, not a fridge mistake, so fix both. Sell beer nearing its date at the counter with an honest word: it is still good but drink it this week. Do not hide it among the fresh stock. Some breweries will swap or credit old stock if you raise it early, so ask before it expires rather than after.
Then cut the order. If a beer sells a case a month, order a case, even if the distributor's minimum makes that awkward. Fewer lines kept fresh will beat a wall of choice that is half stale. Our guide to choosing a beer range for a new bottle shop covers how many lines a small shop can turn.
The hard part of running a bottle shop is the arithmetic of stock days, cash tied up and margin per line, which a fridge routine alone does not solve.
Your first step
Tomorrow morning, take a marker and a notebook to the fridges. Write the packaging date on every case in the stockroom, then pull the oldest beer of each line to the front. You will know within an hour which beers are at risk and which order to cut next.
Common questions
What temperature should a beer fridge in a bottle shop be?
About 3 to 5 °C suits most craft beer on display. Check it with a separate thermometer rather than trusting the fridge dial.
How long can an IPA sit in a shop fridge?
Hop aroma fades within a few months even when cold. Many craft breweries ask retailers to sell their IPAs within about three months of canning, so check the brewery's own guidance.
Are cans better than bottles for a shop fridge?
Cans block all light, so they cannot become lightstruck. Brown glass protects well. Clear and green glass should be kept away from bright light.
