    First VST result

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    For what it is worth here is my first VST coffee.
    My cridentials. Absolute novice !
    I recently purchased a 20g vst ridgeless basket and a jetblack flat 58.35 tamper. (reasonably snug fit, but some wigggle room)
    Adusted my grinder down 3 steps finer from my original rocket basket setting and measured out 20g.
    Flow rate was too slow at around 45 seconds so I will shift my grind 1 notch coarser next time.
    Anyway it was the best flavour I have had from this bean, richer, smoother, great !
    Puck looked good, no channeling. So my concerns regards comments about the vst being difficult to master were not the case. So far so good.

    Yes, they are awesome.
    You should consider to buy/beg/borrow a bottomless portafilter, so as to check your work. There may be taste improvement also.

    More importantly, how did it taste?

    my experience with vsts too. they let the water flow through faster, so you have to grind finer to get the same contact time, and the higher extraction gives you a tastier cup.

    speaking of, scott rao's new trick with the aeropress filters let the water flow through faster too, so you can do another tighten up for an even higher and tastier extraction. people with good grinders and decent machines are hitting 26-27% now.

    I found this photo https://i.imgur.com/RxYUepM_d.jpg?ma...idelity=medium and this post https://www.instagram.com/p/Bw7JZFSnCeb/?hl=en. The first photo is from Reddit so I don't know if it's Scott's or not.

    wow ! So would the grind need to be coarser with the filters ? My cridentials. Absolute novice !

    I found a hb thread about it. Seems like the suggestion is a 10-20 micron filter paper, and a aeropress filter on top.

    According to the comment in the link (emphasis mine):

    Six or seven years ago my friend @soyboyandy told me he had been using an aeropress filter under his espresso pucks to absorb fats and cholesterol. Andy reported the interesting side effect that the filter allowed him to grind finer and extract (1.5%?) higher.

    Wwwow.... that is fascinating... especially about the top filter greatly eliminating channelling which is indeed significant.... I feel some experimenting coming up!

    Yep. Well worth looking in to and testing for yourself to see if you like the end result in the cup.

    Will be testing additional filters on Robot at work and home machine.

    Good utilisation of my aeropress filters, considering I use a metal one for aeropress.

    The HB thread I saw was here:

    Just wanted to point out, Scott Rao might have just started talking about it, but there were home baristas experimenting with the exact same idea in 2015, if not earlier...

    Edit: Make that 2011, if not earlier...

    Do you have a link to the earlier experiments ?

    ......... I tried just the Aeropress filter on the top of the puck this morning for my espresso..... wwwwow. Absolutely blown away, and the difference was actually really noticeable.

    I might make a thread about it tomorrow after I try it again.

    First VST result

    The other up shot of a paper filter on top is it might stop the early death of many machines and save the clogging of many shower screens round the world.

    Haha true.

    Also Sprometheus did a recent video on using the filters in a few ways, and used a refractometer too. Just a quick casual experimental vid which was cool to see. The discussion happening in comments below the vid are interesting too

    Nice one! Iíve got a Make Coffee Not War T shirt for winter time.

    Token bringing back on topic ;-)

    VST plus filter paper seems pretty tasty.

    Tested several with robot at work. Less channeling. Tasted great.

    Shot quality improvement on home machine.

    Would love to see this in action on one of the transparent port filters.

    I will do a cafetto clean on home shower screen then see what it is like after a week of filters on top.
