I’ve been visiting to a bar in Borough for years, and the last time I was there, I observed something strange. I had been drinking the same pale ale all summer, but all of a sudden it tasted thinner. It was almost watery. When I brought it up, the barman shrugged and vanished down the cellar. Ten minutes later, he returned and reported that since the engineer’s visit on Tuesday, the cooling unit had been operating two degrees cooler than normal. Two degrees. That was all it took to transform a beverage I cherished into one I hardly recognized.
When most individuals enter a pub, they don’t consider the temperature. They consider the number of people, the music, and if a table by the window is available. Either the pint tastes good or it doesn’t, and if it doesn’t, it’s simple to point the finger at the brewery. What goes out in your glass on a Friday at half past seven has very little to do with the brewery. It’s in the cellar. The lines do. Things are left half frozen by the glass washer operating on the cycle.
Aroma is suppressed by cold. Nobody tells you that part. When a beverage is served excessively cold, the volatile elements that give it its hop flavor, malt sweetness, and yeast aromas are trapped inside the liquid and you only taste carbonation. This explains why popular beer companies heavily promote the ice cold concept in their marketing. When you are unable to taste a thin beer, it is forgiving. Serving a complex beer in the same manner only makes it thinner.

There isn’t much debate regarding the ranges. Light lagers thrive in temperatures between 3 and 7°C. Pale beers and IPAs like temperatures between 7 to 10°C, which is nearly heated to somebody accustomed to Stella served at refrigerator bottom temperatures. Before they reveal their true composition, stouts and porters must reach a temperature of 10 to 13°C. Additionally, cask ales what English pubs are supposed to be known for prefer 10 to 14 degrees Celsius, which is actually what people mean when they say that the British serve warm beer. It’s not warm. It simply isn’t freezing. Although travelers have been mistaking the two for almost a century, there is a distinction.
Wine is a silent play unto itself. Everyone says, “Reds at room temperature”, but what they meant was a Georgian dining room in 1820, not a London apartment with central heating in May. When a Cabernet is served at 22°C, it tastes strong and alcoholic. The structure becomes clear when you reduce it to 16 or 18. The converse is true for white people, who are served so cold that everything worth tasting has been removed from the refrigerator, leaving just acid. When poured at 8°C, a fine Chardonnay is practically quiet. When it reaches 11 or 12, it will begin to speak.
Strangely, not many places even those that ought to get this correctly. I’ve been served Burgundy that was so chilly the glass fogged as I sat in restaurants with wine lists that were as expensive as rent. The sommelier was aware. He had to. No one was going to return a bottle that was more than a few degrees because the kitchen was busy and the cellar was becoming cold. Everyone went on. Presumably, the wine didn’t.
Although I can’t prove it, I believe there is a sense that the temperature issue is actually a confidence issue. Complaints are a concern for the public. Someone will claim that a pint delivered at the correct 8°C tastes weird, and it feels colder than a Coke. As a result, the regulars who genuinely pay attention wander away to the one location down the road where the management has the thermostat calibrated correctly and isn’t offering an apology as they push the temperature lower and lower.
Glassware is important as well, although very few people discuss it. On a hot day, a frozen mug looks dramatic, but the ice crystals inside destroy head retention and completely drown out the carbonation. The modest custom of rinsing a glass with cool, not cold, tap water before pouring is one that has been lost in most locations but still exists in a few. Pubs that continue to do this are typically the ones where a pint is worth getting twice.
It’s difficult to avoid the conclusion that temperature is the most underappreciated factor in the whole hospitality industry after seeing this unfold over hundreds of pours in several locations. Food is praised. The picture is sent to the chef. The majority of the experience is really decided in the windowless, somewhat damp cellar full with pipes that no one takes pictures of. A restaurant with one outstanding leg is one that has a fantastic kitchen but a poorly managed cellar.
The good news is that fixing any of this won’t cost a fortune. More affordable than a round of drinks is a good digital thermometer. It takes an afternoon to calibrate a cooling unit. It may take 10 minutes to train a novice barman to feel the glass before pouring. The obstacles are inattention and habit, which are tenacious yet transient.
Whether the typical drinker will ever care enough to turn this into a competitive issue is still up in the air. Perhaps they won’t. Perhaps the pubs that stress over five degrees here and there will continue to be a small minority, only known to a few regulars who are unable to explain why their local feels different from the nearby chain. Whether or not it is named, the difference exists and is there in every glass.
