    Single and Double Wall Baskets

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi guys,

    I was wondering if somebody can shed some light as to what single or double walled baskets are and what effect they have on the shots you draw? Ive heard of quads too and was just wondering if I should look into getting any for my Silvia. Thanks!

    Hi Jensen

    Youre getting a couple of things mixed up. Single walled and double walled baskets are as they sound. Most good coffee machines use single walled baskets and rely on the user to adjust the grind, dose and tamp to control the extraction.

    With a double walled basket the inner wall has lots of holes (just like a single walled basket) but the outer wall usually has only one or two holes, and the result is that all the coffee is forced through the tiny hole.

    Cheaper machines use double walled baskets because the extra pressure forces a crema of sorts out of the often cheaper beans/stale grounds put through the machine.


    On the other hand, you might be interested in getting a quad shot (not walled) basket for your Silvia, which basically means a single walled basket that is much deeper than the standard basket that comes with the Silvia, so you can literally fit more coffee into the basket (so double the amount you can fit into a double).

    The extra coffee means you can have your Silvia pump the same amount of water for a double through twice the amount of coffee, which may result in more bang in your shot.

    Cheers

    That definitely clears things up a lot Sniff. Thanks! Looks like I will stick to the single wall that I have since Im more than happy with the shot quality currently.

    But the quads..... hmmm tempting.....

    If you get a quad basket you will need a naked portafilter or a deeper one that accepts the basket ;)

    I use the quad basket from Beanbay (sold out now) with my Silvia. Everything else being equal, it doesnt produce a stronger shot but rather a larger volume. This basket has more holes than smaller baskets allowing more water to be pumped through in the same time. There might be some variation in extractions due resistance differences with puck shape and mass or even tampability but to me it seems neglible. All the puck experts should weigh in here.

    If you dilute your shot/s with water or milk to make a longer drink, when using a quad you can end up producing a stronger drink in the cup (assuming your final volume is unchanged). But you can get the same effect by making smaller drinks (by volume) using a double.

    For the record I use an 18gm double rather than the stock Rancilio 14gm so the quad is closer to a triple for me. Its still not a perfect fit for my newish Silvia even with a naked pf but it will work.* I also tend towards ristretto based piccolo drinks when the beans suit and I want stronger milk drinks but thats just a preference.
