hello fellow coffee botherers in this video we're going to be talking about espresso Brew temperature Brew temperature is very important for all Brew methods of course including espresso but for espresso specifically it's often a cause of confusion and frustration I get a lot of emails relating to brew temperature and I've been getting a lot more than usual lately so I thought I'd cover it here and try and demystify it a bit this is going to be a short video because thankfully this is actually quite straightforward to explain there's not a lot to it but it's one of those things that once you know you know you know but but hopefully you'll find it useful temperature tip number one understanding what we actually mean by Brew temperature a very common email I get goes along the lines of this Kev is my machine faulty the espresso temperature is way way less than I'm told the espresso Brew temperature is supposed to be what we mean by Brew temperature isn't the temperature in the cup it's the temperature of the water as it's entering the basket your espresso will always be cooler than the brw temperature which is good I don't think anyone really wants to drink 94° Celsius espresso you can usually expect a difference of around 15 to 20° C from brute temperature when measuring the espresso temperature so your espresso is likely to be mid to high 70s or very low 80s in Celsius around 170 to 180° fah so now you know if your espresso is cooler than the brw temperature that's because it's supposed to be if your espresso is below 70° C or below 160° Fahrenheit then there may be something going on I'll tell you what to do in the next tip which takes us to tip number two understanding how pressure affects temperature if you have a thermac coil or thermal block espresso machine including all of the 54 milk Sage or brevel machines pressure is required for brew temperature to be as expected if a shot runs way too fast because the grind is too Co that will also mean that the pressure in the basket is less than expected so the water doesn't have the expected contact time with the heater so the brute temperature will be cooler and the espresso will be cooler this is the reason that many people think the machine is broken I can't tell you how many times someone has told me they've actually returned the machine for this reason in fact more than one person has told me they've returned the machine for having this fault and then the replacement had this fault too so they gave up and went for another brand one person told me that they had two Replacements and they both had this fault the machine didn't have a fault they were doing it wrong no they' stumbled across a Reddit thread or something about Sage or brevel machines having a temperature issue and there were a couple of videos actually here on YouTube where people appear to be showing this fault but it's not a fault they're a fault this fault is measuring the water entering the cup from the group or from the pter filter with the standard baskets when you do this the water will hit the cup at around 65° cus or 150° fahr simply because it's the way thermal blocks and thermac coils work there needs to be pressure in the basket in order for the water to have the extended contact time with the heater to prove this put the Dual W Basket in the pter filter and then run a blank shot and you'll see the water temperature significantly increases to around 80° C just under 180° fah because it's now having the expected contact time with the heater temperature tip number three don't underestimate the importance of preheating your machine most espresso machines when they give you the ready light to signal that they've heated up this only means the water heater is up to temperature so with the Bambino Bambino plus brista pro and so on it's 3 seconds how hot do you think the Brew path the group and the porter filter are going to be after 3 seconds about as hot as something that isn't very hot roughly pulling a shot straight away before you've heated the internals and the group will result in the Brew temperature being cooler than expected with most machines if you do have a thermac coil or thermoblock machine and you have a dual wall basket sitting in a drawer somewhere hopefully you didn't chuck it away these are perfect for using to properly preheat your machine what I call a turbo flush is when you do the preheating flush basically one or two blank shots but you do it with the Dual W pressurized baskets in the porter filter this creates pressure in the basket in the machine is heated up at full Brew temperature bonus tip number four always preheat your cup when espresso machine Engineers are called out to cafes who've reported that the Brew temperature isn't right the first thing a decent engineer will do is to check that the BRS are putting the cups on the cup warmer the right way round so the bottoms get heated not the rims that's literally all it takes to stop a cup from becoming a heat sink in commercial espresso machines many home machines don't have usable cup warmers so preheating the cups is always worth doing and you may as well anyways it saves drip Dray space when you're preheating the pter filters so all you need to do is put a cup on under the portter filter when you're doing your turbo flush and that's it short but sweet I hope you
