"Hey - HBers, I have this wonderful Cremina but my coffee always tastes like old burnt plastic! Any ideas?"
- "This is easy: you just need to tighten your grind and reduce the dose."
- "Wrong! - Wrong! - Wrong! You have it backwards! FIRST reduce the dose and THEN tighten the grind!"
- "But you're using a lever machine! How could this be???"
- "Have you checked the TDS? You may be getting 20%, in which case your beverage is ideal even though it might taste awful."
- "No question: your coffee is stale. Anything over eight days, three hours and you get a floor of old burnt plastic under the leather and tobacco overtones."
- "You need a (convex / flat) tamper with a (polished / copper / de-magnetized / fair-trade) base."
- "I got that same taste once but it was with oily beans that hadn't de-gassed."
- "Maybe you have one of those models with an old burnt plastic piston. Oh ... ... wait: that's La Pavoni. Sorry!
- "Nah, it's all those fines from your SJ. A Zar will fix you right up."
- "You know, the elements in the late '70s Creminas are known to overheat if the mineral content of your local water is over 150ppm. I'm sure if you rig in a Flojet the bad taste will go away."
- "Wait a few days: my experience is that coffee never comes out tasting like old burned plastic on Thursdays."
- "Remember 2-2-2-2: backflush every two minutes, de-scale every two hours, rebuild every two days, buy a new machine every two months. Sorry to be the bearer of bad news, but it's the only way."
- "You must be using *$s. You wouldn't have this problem with Red Bird."
- "Maybe you need to backflush more often. Oh ... ... wait: that's La Pavoni again! Oh ... ... wait: maybe I meant Faema! LOL! Sorry!"
- "I use VST baskets so I've never have that particular problem. Of course, I'm also using a Linea, so I never have any problems at all."
(Or you could just take that hunk of old burned plastic out of the boiler.)
