    larger volume boilers have a faster recovery time between shots and that bit of extra steam so that you can produce 6 cappuccinos in 5 minutes for your dinner party Again in my experience the Gaggia boilers tend to corrode internally They are an aluminium upper part attached to a brass group and the combination of dissimilar metals and hot electrically conductive water creates a galvanic battery which simply eats the aluminium This can also happen with aluminium thermoblocks which is why some of the more upmarket ones are now lined with stainless steel Finally the larger brass boilers tend to have higher power elements than the smaller stainless steel ones again giving better thermal stability and faster recovery Lelit s 300ml brass boiler The standard S S boiler on the left and the Silvia boiler on the right Big isn t it Inside an 18 month old Gaggia boiler The aluminium top has corroded the chromed brass base is in perfect condition This close up shows the extent to which the metal has been eaten away Aluminium Thermoblock 10 ml Aluminium Boiler 120ml Stainless Boiler 180ml Brass Boiler 300ml Most Sunbeam Cafe Series Breville Krups 2000 4000 Series Saeco Solis Gaggia Superautomatics Gaggia all local models Chinese made cheap machines often available on Ebay Saeco Via Venezia Nemox Napoletana Junior La Pavoni Delonghi Sunbeam Cafe Roma Lelit Imat Mokita Series Nemox Opera Fenice Rancilio Audrey Silvia Lucy Solis SL70 SL90 Spidem The GROUP is the bit of the machine that the portafilter locks in to where the water is pumped through a showerscreen on to the coffee All of the thermoblock machines I ve seen have aluminium groups with stainless steel shower screens The smaller stainless steel boiler machines also have aluminium exterior groups and S S screens Gaggias have a brass group with a S S screen brass boiler machines have brass groups with S S screens Of all domestic machines only the Rancilio Silvia has a commercial brass group and S S screen setup Portafilters and pressurized filter baskets are another point of differentiation with again thermoblock machines tending to have cheap aluminium portafilters and quality boiler machines chromed brass portafilters All this concentration on metal types may seem a bit strange but excellent espresso production relies on thermal stability of all the components in the process Copper and brass are best which is why you find them in commercial machines This Chinese made machine has a plastic group and stainless steel showerscreen The Rancilio Silvia group solid brass with commercial showerscreen and water distributor Pressurized portafilters Krups on the left Saeco on the right Unpressurized portafilters Rancilio commercial pf on left Saeco Solis Imat Nemox unpressurized on right Both Gaggia and Rancilio use commercial portafilters and baskets on their domestic machines although the recent Gaggia Cubika has an aluminium portafilter Solis and Imat have brass portafilters but non commercial filter baskets Saeco uses its patented pressurized portafilter made mostly of plastic but with some brass as

    and detergent will do for the portafilter and baskets The showerscreen can be wiped with a soapy sponge as can the rubber gasket The gasket can also be cleaned of grounds with a brush a bent kiddy toothbrush works well Remember to rinse everything clean you don t want detergent flavoured coffee About once a month the showerscreen can be removed for cleaning It s important to use the correct sized screwdriver so you don t strip the screw there are pictures with this month s internet newsletter showing the procedure Use a scotchbrite with detergent to clean the group and if the screen is really dirty and the holes are blocked a wire brush can work wonders When you replace the showerscreen the screw should only be finger tight In between the daily and monthly cleaning machines with solenoids can be backflushed about once a week to clean out the showerscreen and water path to the solenoid Lelit group and showerscreen Removed and cleaned Silvia group and showerscreen Cleaned note water distributor washer IMPORTANT NOTE None of the domestic espresso machine manufacturers recommend backflushing and any damage that occurs while you re doing it will not be covered by warranty That said there is an excellent how to tutorial on Randy Glass website at http www espressomyespresso com that takes you through the necessary steps You do need accessories like blind filters and espresso machine detergent Silvia Portafilter with blind filter basket Lelit Portafilter with modified single filter Unfortunately no equivalent basket exists for the Lelit machines so again there are photos on the website showing how to make do I use a circle of self adhesive foil tape in the bottom of the single filter basket as you can see Finally machines should be descaled about every 6

    portafilters make to a shot In the spirit of enquiry I cobbled together a burnt out Saeco machine using spares from several other duds and then experimented with both the pressurized and non pressurized 53mm portafilters My findings were as follows 1 You HAVE to use a moka pot grind with the pressurized PF a proper espresso grind chokes the flow 2 The espresso produced has a thick slightly frothy crema but is underextracted with a thin body and a sour taste 3 The same coffee used in the ordinary PF but with a correct espresso grind has a dense crema full body and sweet flavour My conclusion is that pressurized portafilters give the appearance of a good shot although the crema is a bit pale and foamy but do not make up for extraction deficiencies caused by the coarser grind Throwing caution to the winds I tried some brick packed Vittoria and got a 10 second crema free shot with the normal PF and a 28 second crema laden shot with pressure The pressurized shot had a higher level of extraction due to the longer brew time but both shots still tasted pretty foul My overall take on pressurized systems is that you can get better results from poorly ground coffee than from non pressurized systems but there is no substitute for correctly ground coffee Of course correctly ground coffee won t work in the pressurized PF so by and large the pressurized faux crema producing portafilter is a marketing gadget not an improvement This month s special coffee has a story attached to it it comes from one of PNG s rare indigenous economic success stories The Sihereni coffee plantation was rehabilitated after being abandoned for many years by David Oromarie and now produces some of the finest
