What Is Temperature Surfing In Espresso Machine

Most espresso machine companies have short-listed 1 objective for the very leading of their list: supply you with all the proper environment to pull the best shot achievable. Like the perfect storm, the right situations hinge upon having the perfect stress and temperature. For espresso enthusiasts, finding the perfect formula for every shot requires ongoing trial and error. A significant point of interest and case study, of sorts, in the coffee community involves a technique called “temperature surfing.”

Why Temperature Surf?

Temperature surfing may be performed numerous ways, but its ultimate aim would be to get the best brewing temperature out in the group head. Whilst most semi-automatic machines are equipped with thermostats to help regulate water temps, the thermostats concentrate on controlling boiler temperature. As some coffee lovers have noted, there is always a variation often minor, other occasions noticeable, in between the boiler and brew group temperature. Also, some machines might brew too hot and other people too cold for your liking. Temperature surfing will help you get closer to your target brewing temp.

Even though it’s a matter of private preference, and you can certainly make great-tasting espresso with no using this strategy, the theory behind temperature surfing relies on normally accepted coffee logic. If brew temps are too cold, you will find yourself having a sour, lackluster shot. If they’re too hot, your espresso is probably to be bitter. Also, optimal brewing temperatures could differ for different roasts and blends. You might discover that a light roast tastes just proper at one temperature but a dark roast might need a slightly various brewing environment to extract the perfect shot.

Will Temperature Surfing Harm my Machine?

Temperature surfing is totally secure when accomplished effectively and can not negatively have an effect on your espresso machine. Under normal circumstances, it won’t influence your warranty either. If you strategy to attempt temperature surfing, though, be sure that your machine has lots of water to prevent a dry boil-which has the possible to harm the unit.

Is Temperature Surfing Worth It?

Again, we defer towards the tech division; but this time there isn’t a clear consensus of opinion. It essentially boils down to this: Temperature surfing will add further time for you to your brewing routine and it is not an exact science. Even if you select to temperature surf, you nonetheless won’t have complete manage. Let the steam run too lengthy on a single boiler machine and you danger brewing too hot. However, having a heat exchanger, if you run too significantly water by means of your group head you may be brewing too cold.

Our tips is…let your taste buds be your guide. If your espresso tastes its best right after you’ve temperature surfed your machine, excellent! If you just like the espresso your machine tends to make as is, with out temperature surfing, a lot more energy to you! This is a component of the art of espresso; it’s exciting, experimental and occasionally oh so subjective.


Some Semi-Automatic Espresso Machines may have the tendency to brew a tad too cold for your liking. This may be the case when the maximum temperature in the machine’s thermostat is on the lower side. Even if the machine is within the perfect temperature variety, if you desire to brew a bit hotter, you can do so by “tricking” the unit into thinking it truly is about to steam rather than extract.

Because these machines use the same boiler to brew and steam, there will likely be a natural temperature variation among the two functions. For extracting espresso, the boiler temp for many machines is lower than it will be if you have been to steam or froth milk. Hence, you can trick the machine into raising its boiler (and in the end brewing) temperature, by activating the steam function as quickly because the brew-ready indicator light comes on. The longer you leave the steam function running, the hotter the machine temperature will be. As soon as you’re prepared to brew, turn the steam function off and extract your espresso correct away, prior to the boiler features a possibility to cool down.

Heat Exchangers

Heat exchange machines-with the exception of dual-boiler units just like the Expobar Brewtus models and the Pasquini Livietta T2-could brew slightly too hot for some users. The cause for this is due to the fact the water you are brewing may have been heating inside the boiler for an extended time period if the machine has been left on. The water, which will work its way through the group head when you extract a shot of espresso, might be close to boiler temperature-over 212?F and too hot for brewing purposes.

To be able to steer clear of extracting your shot with water that’s too hot, merely take away your portafilter and run water by way of the brew group. In the event the water that’s flowing by means of machine is too hot, you’ll see fine wisps of steam emanating from the group head. Continue to let water flow by means of the unit until the steam disappears, this can be your indication that you have purged all the overheated water from your machine. Make sure you have your portafilter filled, tamped and waiting on the side. To brew, simply reattach the portafilter and adhere to through with your standard routine.
