VST 7g how much coffee
I bought a 15g VST basket, but it's too large for a single and too small for a double, at least for me. As I usually make single shots, I'm thinking about getting a 7g VST. I was wandering how many grams of coffee I can actually put in that basket. I have single shot basket which came with my ECM. It has similar shape as VST, and takes up to 13-14 grams. Would VST 7g have roughly similar capacity?
I also have an ECM and currently use the standard baskets. Personally, I dont use the single basket, i've always found it tempermental and if I use it beyond 8-9g dose, i need to adjust my grind from a standard double basket grind, which I avoid. For me, i either have a double shot or just split the shots, often having one as a macchiato and other espresso or something.
Im looking to buy a VST soon, I'll likely run an 18g and just use it the same as i do now, splitting the shot.
Thanks for the reply.
For me the consistency of shots from a single ECM basket is better with 12g of coffee or more.
That's why I bought VST 15g. Was hoping it would be OK for singles, but it's too big in my opinion.
I do like using finer grind for VST, so I thought I would give 7g a go.
Im using the 20g vst, weighed 20g of coffee, works really good for me, no problems with vst.
I think its just what machine you have and what basket you use. And just trying and doing it until it works for number 1 (you)
7 gram VST = nightmare.
14g dose in 15g VST = can be a little tricky with how fine the grind needs to be and really light tamp. I rather 15.5g = more forgiving.
If you like dark roasts and tight shots, you should be able to pull a 20g shot weight from a 14g dose in 15 VST in around 30 sec = delicious syrupy little sip

Or, from another point of view, the Italians do not know what they are talking about when they use singles. 50 years of mistakes from them? Everything else they do seems fine!
The fresher the roast and the better the bean, the more flavour you can unlock. Stale supermarket roasts: 15+g to try to get any flavour out of them.
The better the grinder, the more flavour you can unlock. I use a pair of Mahlkonig Vario gen2's as (my opinion here, after 50+ personal grinders please do not flame...) they are by far the best domestic grinder.
Using a VST you end up with extraction rates (i.e. flavour whack) about 50% higher than the traditional 15%. The fact that daro finds the 15 too strong is a pretty clear sign that he is getting a good extraction rate from his VST.
Combining the above makes a 7g not only feasible but a latte can still be too strong for some people.
Dosing it within "VST recommended" range (6 to 8g) works fine. I usually use 7.2g as it suits my gear. I freely admit that setting up a VST 7 can be impossible on some gear and highly problematic on others. My harsh answer - forget it or upgrade your gear / grinder / technique as needed.
Back to the OP.
Hey Daro - please remember that the 7g has very little latitude for dosing error (10% will swing the pour significantly). You will need a little patience to sort it out. If you are overdosing the 15g, lowering the dose to 14g is perhaps a better starting point (easier than Steve82 makes out) and then advancing from there. Although one poster reckoned he can put 16g in his 7, I would not recommend it.
