For a while I've used the special custom piston seals that LONDINIUM had available for their lever machines (currently / temporarily out of stock). These are fractionally wider than the standard seals and the inner lip is fractionally higher: These custom seals are especially helpful in the first generation LONDINIUM which has pre-infusion at boiler pressure. In that configuration it's essential that when raising the lever, after the puck is fully saturated, the lowest seal when sliding down immediately 'spreads' its lips, pushing down on the air pocket and brew water with nothing 'slipping' upwards past the seal. Then all remaining spring pressure is available to initiate the espresso shot. A friend who currently owns my first LONDINIUM has tried the blue silicone seals that Cafelat produces for a number of lever espresso machines: https://www.bluestarcoffee.eu/cafelat-group-lever-gasket--kit-11890-p.asp The same friend later reported that the piston had troubl...

I have scooped off the coffee pucks and put them in a plastic container, kept outside on my balcony, with holes drilled in the bottom so excess moisture can get out. Maybe it will compost better there and if it does I can spread some of the resulting material on the potted plant soil. https://balkonton.nl/wormenbak-compostproces-versnellen/   Geef je compostwormen een cafeïne-shotje Net als mensen worden wormen actief van cafeïne. En actieve wormen hebben meer honger. Volgens sommige wormenkenners mag je compostwormen niet te veel koffieprut geven. Omdat ze daar gestresst van raken. Anderen zweren juist bij koffieprut, omdat het de voortplanting zou stimuleren: Ook op sex gebied worden de w...
