bro, had a go at the oscar today, difficult to steam the milk for micro foam, also impossible to pull shot without a scale but tried anyway 

any tips?

hopefully get a scale next week

i have been making 2 shot every morning with double basket portafilter. i make one shot into latte & discard the other one short. wonder does anyone doing the same thing like me with their oscar. i only need single shot, but believe that single shot portafilter may affect the quality of shot ><
i use fresh espresso blend rm 60/500g. Lately placed order for 500g lebistro coffee. How to follow up the order? How long it takes to deliver?

What's a double ristretto pull from 18g?
Ristretto on 18g is like 15 ml liquid. Double ristretto is double the liquid?

Or pulling 2 ristretto from 18g so total is 36g coffee used?

For Ristretto, you grind finer, so that it blonde with less volume, for a more intense sweeter cup. Generally still within 25-35s. It's not done by selectively cutting short extraction for 2/3 of the flow. The sweetness comes from the intensity...much like drinking wong lou kat and tan an lou herbal tea...the balance comes from getting the proper extraction...I occasionally screw up and had to go to 45-60s to blonde ...still makes a good cap.

A double basket is much easier to tamp right...that's usually why it's said to be better...a single is just as good if you know how to manage...

hi guy fill up double basket and make 45ml coffee from poemic, is that correct way ??? taste is ok but if i pull a little bit more (60-75ml) it feel bitter or what should i do ???

beans : buy here, shop and online. (no knowledge on everything other than drink)

*snip*
On the topic of throwing away espresso and waste. Is ristretto a waste? Throwing our beans that is half extracted?

the original one lo ... i just get the machines for less than two week, which still know nothing abt it

how often do we need to backflush the oscar?
