  • jimbow commented on the thread From no machine to new machine.
    The thermosyphon is a sealed circuit that runs from the HX to the group head and back again (the return). As water in the HX is heated...
  • jimbow commented on the thread v60 Grind Comparison!.
    How much water do you use for the 17g brews?
  • jimbow commented on the thread 2 steam tip v 4 steam tip.
    Try blocking one, or two, of the holes in the four hole tip with the end of a cocktail stick. Sounds naff but it works.
  • jimbow commented on the thread v60 Grind Comparison!.
    Interesting. I think with brewers like the Chemex and Wave this is definitely true where different sizes of the brewer have different...
  • jimbow commented on the thread v60 Grind Comparison!.
    I have never gone to 30g, I think the highest I have gone in the 01 is 24g which definitely worked better in the 01 than the 02 with my...
  • jimbow commented on the thread v60 Grind Comparison!.
    Buy a Kalita Wave! Just kidding. This to me is the blessing and curse of the v60 - the level of control you have over the brew but...
  • jimbow commented on the thread 2 steam tip v 4 steam tip.
    The angle of the wand in relation to the milk is important regarding the number of holes and their positioning in the tip. If you have...
  • jimbow commented on the thread 2 steam tip v 4 steam tip.
    Frothing the milk comprises two phases: stretching (adding air) and texturing (integrating the air with the milk). All the while...
  • jimbow commented on the thread Cherub - First Impressions.
    That's good to hear Shrink. As you said earlier, the shower screen protrudes quite far into the basket on the Cherub which limits the...
  • jimbow commented on the thread My first Chemex!.
    Some people like to keep the slurry low in the Chemex (as with the v60). This is the technique advocated by Scott Rao and sparked off a...
  • jimbow commented on the thread Dear Santa, I would like....
    I have a Compak K3 Touch and am fairly happy with it. Compak Grinder designs are extremely similar to Mazzer but at almost half the...
  • jimbow commented on the thread v60 Grind Comparison!.
    Go on, you know you need one! I must admit, my wife always laughs at my brewing kit: aeropress, french press, v60-01, v60-02, v60...
  • jimbow commented on the thread Piccino brew temperature.
    Have a search for the polystyrene cup temperature measurement technique. This will give you a slightly more accurate temperature...
  • jimbow commented on the thread new fracino drip tray.
    Try using slightly more milk and chill the milk in the jug before steaming - this will buy a little more time for stretching. Only...
  • jimbow commented on the thread new fracino drip tray.
    The thermosyphon on the Cherub is a separate sealed circuit that runs through the boiler, indirectly heating the brew water within the...
  • jimbow commented on the thread 2 steam tip v 4 steam tip.
    Here was another thread about 1, 2 and 4 hole tips on the Cherub: http://coffeeforums.co.uk/showpost.php?p=54631 I use a 4 hole tip on...
  • jimbow commented on the thread Cherub - First Impressions.
    You can calculate the temperature of the water in the boiler as a function of your height above sea level and the pressure read from the...
  • jimbow commented on the thread Cherub - First Impressions.
    Mine tops out at 1.0 bar with 0.85 at the low end
  • jimbow commented on the thread Cherub - First Impressions.
    Turning the spouts around would give you more room but bear in mind it would affect how the portafilter sits when placed on a work top...
  • jimbow commented on the thread Cherub - First Impressions.
    I was surprised as to how good the first shot on the Cherub was. Without changing the grind (or other brew parameters) from my Gaggia...
  • jimbow commented on the thread Gaggia classic shot timing.
    Okay and how about if you attach the portafilter to the group with an empty basket?
  • jimbow commented on the thread Cherub - First Impressions.
    A coarser grind might help. I find that after switching the machine on and leaving it for an hour I need to flush around 2 Fl.Oz...
  • jimbow commented on the thread Gaggia classic shot timing.
    How easily does the water flow from the group without the portafilter attached? For example how much water is dispensed in 10 seconds?
  • jimbow commented on the thread Has Bean - In My Mug.
    +1 from me.
  • jimbow commented on the thread My first Chemex!.
    As MMJB said the filter papers are different with the Chemex papers being considerably thicker and so requiring a coarser grind. Also...
