Single Shot Vs Double shot
Using Breville Smart grinder pro/ Lelit Diana Machine.
I have tried using the single cup basket that it came with if I am making a single coffee for myself but it never seems to work properly and I tend just to use the double basket and end up with a stronger Coffee. When the wife want a Coffee also I'm pouring 2 shots so it ends up being a more "normal Strength" Coffee. Reducing the amoutn of Coffee in the basket obviously doesnt work as you end up with a sloppy mess.
Are there any tips to effectively use a single basket or should I just be happy that I have a double shot coffee !
How many grams is going into your single vs double? That and how much ml out you are getting is probably the most reliable way to tell what is working and what isn't.
I'll check and do a test. With my current beans my grinder grinds for 15sec for a double but will check on how much weight that is

In my experience so far, once you get the grind and dose correct, you get a pour that starts out as a trickle stream (not dripping) that is caramel in colour with darker ribbons in it which then picks up pace towards the end of the extraction to a bit more of a thicker stream of blonder looking (but not cascading). The end result of a double shot should be around 60ml in which case you nailed the extraction.
The breakthrough I had, was the dose. I was under the impression that I needed to pack the single wall basket up every time (which i used to do in the dual wall basket using supermarket beans) so that the silver section of the tamper was only just visible. But for freshly roasted coffee in a single wall basket, this will choke the machine most times. I started using accurate scales to get a double shot dose of about 17 grams of ground coffee and even though it seemed a lot lower that I am used to, the coffee was instantly better.
If you are choking up, I wouldn't be afraid of lowering your dose and leaving the grind setting around 14 (for fresh roasted). I know you say that it will get muddy, but I haven't found that to effect the extraction. If you try and go courser and keep the dose high, in my experience Ive ended up with a bad result.
The settings i currently used on my grinder pro for 2 shots of freshly roasted coffee in a 58mm double shot basket (BES920) is 16.6 seconds, with a grind setting of 14. I don't use the single shot basket very often but if you start with approx 8 grams if you have scales or maybe about 8 seconds of grind and adjust dose up and down until you find the sweet spot.
Unfortunately this is one of those situations where something that works for me may not work you your machine or coffee.. But I hope it helps, because I myself was looking for this kind of information when I got the grinder.
