  1. Distilled water will taste the same no matter the origin. Only reason I can think it would be different is if it was stored on a container that would leach flavour or it hadn't be properly sterile. As for batch to batch variation I can't comment as this will be my first attempt trying them. It is fairly easy to make it consistent in fact you can buy the ingredients in bulk and make your own mixture. CaCO3 is really all you need Sent from my SM-G950F using Tapatalk
  2. If you use distilled then you guarantee the same results across the world. When using RO there may some differences depending on the system used but they are probably negligible for taste...
  3. They all produce different purities which is way I used the V60 and the Kalita example. Even for brewing coffee RO and distilled may be quite different depending on the particular arrangement of the RO system. An RO system is normally composed by at least a particle pre-filter, carbon filter, RO membrane and in some case a DI resin to bring the water to TDS 0.0. However many of the home RO systems don't use the DI resin at the end because you don't want to drink 0 TDS water (isn't harmful but you will lose some salts). What some cafes do is bring the TDS to 0 and then remineralize it so you can control its properties. The advantage of RO vs distilled is cost essentially although it wastes more water. So like in coffee brewing it all depends on how pure do you need the water to be, how much it costs to achieve it and in what scale you can do it. So yes it all gets a bit complicated and it is probably outside the scope of this thread, for this particular tasting because you will remineralize the water so you essentially want 0 TDS or as close to that as you can possibly can get. Most cafes should also able to provide you with RO that is 0 TDS or very close to it so will fish/aquarium stores. Be aware that if you are storing in a container for long term you want that container to be sterilized as the water does not contain chlorine anymore so bacteria can and will grow on it if you give it enough time
  4. They both are purified water so in a sense they are the same thing H2O. At least the same way that say a V60 and a Kalita produce the same thing, brewed coffee Sent from my SM-G950F using Tapatalk

  6. They essentially achieve very similar things so they are often confused. Distilled relies on boiling water at 100C and then condensing the vapour. Because different substances have different boiling points you can have pure water that way. Reverse osmosis achieves near purified water by passing it through a membrane that binds ions and large molecules, water is normally passed through the membrane simply by pressure and it is often combined with other types of filters either before or after the RO membrane. It also normally has a TDS slightly above 0 but different systems will have different tds outputs Sent from my SM-G950F using Tapatalk
  7. That is the stuff Sent from my SM-G950F using Tapatalk
  8. Not at all. You will be able to use them multiple times. Did you refill the boiler by pressing the brew button and opening the steam valve until water flows through? Sent from my SM-G950F using Tapatalk
  9. If you want to convert the machine to 220/240V you will need to replace the solenoid and the pump for their 240V versions as well as rewire the heating elements. The other option would be to buy a convert that allows you to run 110V on 220/240V sockets. Both options however are probably as expensive as buying a second hand gaggia classic though so it will depend on what else you have done to your machine
  10. Yes that is for 40 hours per week although I am apparently slightly out of date as that was the value for 2017. It is now on €600 per month (€8820 per year). Other countries in Europe have even lower salaries. But the main problem is that about 60% of the working population is on that salary which means taxation on anyone above that needs to rise pretty quickly which explains the large number of young people that have moved abroad for work. People do more with less money as there is more "free" help between communities and housing and raw food tend to be way cheaper than the UK. Outside Porto and Lisbon you can for example get a full cooked meal (soup, main course, bread, dessert) for as low as €3 euros and you can rent a 2 bedroom house for less than €200 month (way less in some cases due to rent freezing for several years, my parents have some tenants on €25 per month). So yeah you don't see a lot of Londinium and monoliths around let's put it that way...
  11. €550 per month. Although that is technically 14 months so €7700 per year Sent from my SM-G950F using Tapatalk
  12. Yes the first time I read his high extractions posts I was actually curious. In many ways he was following the ideas of barista hustle on that theoretical you should try and extract as much as you can. The problem was that he is trying to claim the measured extraction on his uncalibrated equipment using a non standard protocol which is hard if not impossible to compare with others. Now if he simply sticked to say I am trying to increase my extractions and this is how I am achieving and measuring it I would think it would be a good read. But instead he insisted in claiming he hold universal truth and then got annoyed when someone questioned his methods as non universal. His attitude didn't help either Sent from my SM-G950F using Tapatalk
  13. I have to agree with this. I am not Italian but Portuguese where the situation is similar. An espresso can be had anywhere from as little as €0.40, quality is certainly better than most UK high street stores but not as good as speciality coffee. With a minimum wage of €550 convincing anyone that they should pay €2 or more for a coffee is madness and most people that brew at home have some kind of capsule system for convenience and use the cheapest capsule they can find since they all taste similar anyway when you add 6/8g of sugar. Just last month I brewed some rocko mountain from foundry for my parents as I wanted to test a grinder we inherited from a cafe and they found the coffee way too strong and preferred the cheap stuff from the supermarket Sent from my SM-G950F using Tapatalk
  14. I think that in order to GDPR the user account and any personal information would have to be deleted? But the posts I am not sure, changing them to guest would be a good idea but if his account is gone it probably does not make much of a difference Sent from my SM-G950F using Tapatalk
  15. If you use a set of pliers to press the metal tabs it will relief the pressure enough that you can pull the tube out. Do you have the intake immersed in water? Sent from my SM-G950F using Tapatalk
