    Crema stopped forming

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi - requesting elementary help please. Crema stopped forming a few days ago and I don't know why. Nothing has changed except the cup seems hotter. Domestic setup, Sunbeam cafe series. Pressure the same, coffee the same. I cleaned the machine but it didn't help. Tips appreciated - this is very distressing! Thanks.

    Hi Icon, crema typically diminishes with coffee bean age, may be worthwhile to check freshness of your beans, alternatively, did you wash your portafilter with diswashing detergent lately? That could also contributes to your missing crema. Please let us know how you go

    Welcome to CoffeeSnobs,

    I hope we can be of help. Let us know where you get it and what type and aged coffee you use. Supermarket coffee may have been good once but typically it has a use by date up to 2 years after roasting as a guide for when it is taken off the shelf.

    I roast my own and general use it within three weeks. Many roasters, speciality coffee shops and cafés sell fresh coffee beans with the date roasted on the pack.

    Also which filter basket do you use? The double walled baskets are made to get some crema with old stale coffee. Single walled baskets give better results but require more skill in dosing and tamping and fresh coffee, ground as required is best.

    Thanks - you might be onto it with the bean age. I'll pick up some fresh roast and try that.

    I've changed several things one at a time, but still no crema:
    -bought a Breville smart grinder (my old Breville died a while back)
    -changed coffee from store-ground Lavazza black (used it since the grinder died, with good crema) to some oldish beans of the same brand
    - bought some fresh roasted Blackstar houseblend
    - reduced temp by 2 degrees (I had noticed the coffee seemed hotter).

    So, while the coffee tastes much better, I still don't get to lick the crema out of the cup. I'm stumped.

    What do you use to clean your portafilter?

    Buying some decent fresh beans from a good roaster Icon (not Lavazza) from a specialty roaster will go a long way toward solving your problems.

    Re washing the portafilter in detergent, I do it daily, has absolutely no affect on the crema and stops the oil and grot from building up, just give it a rinse under the hot water tap after washing to get rid of soapy residue.

    I'll say it again, fresh beans from a quality roaster like Coffee Snobs CoffeeSnobs - BeanBay - Roasted Coffee will make a big difference.

    I'd get a D- on that. I've just been rinsing it. Now I look, it's quite black, but it runs freely. I will adopt Yelta's approach and use detergent. Do you take extra steps?

    I use a botomless portafilter so cleaning is dead easy just rinse and wipe. I hope you find your crema mojo back soon. Fresh bean and well cleaned as well as rinsed machine should put you on the right path
