The volume indication 100 ml refers seemingly to the brim filled vessel, ie a double espresso can be sure it does not accommodate. An espresso in the portafilter (Bezzera Magica) with decent crema to be slowly poured from the jug into the cafe latte glass remains attached to the to small spout and then runs along the outside of the vessel. Either poured the espresso so on the work surface or flips him uncontrollably into the glass - the result is suboptimal in any case, of controlled, clean work can be in any case no question. Therefore, I can not recommend this product.
