verybarista IMS Big Bang Precision Filter Basket for 58mm portafilters, 20-22g. double espresso (h25.5)

A very well made filter basket that is giving me consistent results. Fits my 58 mm portafiller perfectly and is ideal for my preferred 18.5 g dose.

Although I have not been able to use these as yet, I think that they will do a great job. Unfortunatley, they don't quite fit into my portafilter. They won't push down far enough for me to be able to lock the portafilter into the group head. My options are to either spend more money and obtain a bottomless compatible portafilter and gamble if it will work with my machine, try to return them as they are not cheap to buy or keep them on the basis that my current espresso machine may not last a long as perhaps I would like it to (speaking from experience, 12 months seems to be the dead line literally). I know that if I were to purchase a good semi-professional or professional machine these filters will fit, but I might have to store them for some time before that prospect comes into fluition. The filters themselves are of very good quality from the feel and look of them, but I can't really review the outcome of using them as I can't use them at this point in time.

I have a Rancillio Silvia and make two americanos at a time, but was finding them a little lacking. This filter has resolved the issue, yielding the strength of coffee that we like for two people at once. Quality is top notch, I've been using it for a year or so and no sign of tarnish or reduced performance. Recommended.

A lot better than the one that came with my machine Fracino Pacino fits good in the 58mm porrafilter I use about 19gr coffee 2 small cups.

Very good basket to upgrade to. My shots are more consistant with this basket and better extraction.

With the stock basket in the Oracle Jet and the tamp fan on its lowest setting (my screw is touching barely any metal) I was getting 19.3g. With this basket on the same tamp fan setting, I’m getting 17.3g. Using Single+ shot mode I get around 37g out so perfect for me. No wavy tamp issues though I do tend to heat up the portafilter before using by purging hot water.

I had no idea there was even such a thing as a precision basket. I only found out because I asked ChatGPT what tamper to get and it asked me if I had the standard Rocket basket or a precision one such as an IMS… down the rabbit hole we go. Holding the original Rocket and this Big Bang side by side there is an obvious difference in machining. The inprovement is incremental but definitely worthwhile.

Quality and presentation was great but unfortunately the lip on this was too deep to fit my two different 58mm portafilter heads. Anyone looking for Breville Slimline - this does not fit the group head.

Tastes great

Bu sepettin akış tarzı diğer ims sepetlere göre daha başarılı. Kolaylıklı Nano ve compettion sepetlere oranla daha ince öğütüm yapabilirsiniz. Refraktometreyle ölçtüğünüzde çözünmenin daha iyi olduğunu görüyoruz. Fakat bununla beraber bu sepetin altında yan kısımlarda çok fazla boşluk var. Bu boşlukların oluşu oraya delik koymamasından kaynaklı akışı merkeze yönlendiriyor. Bunun bir olumsuzluğu var ki mutlaka kahve puckını sepete kenarlardan yapışıyor. Nano sepetlerdeki gibi kusursuz bir yapışmama özelliği beklememeniz gerekiyor. Sanırım bu yapışmaz kaplama bu sepetlerde mevcut değil. Orta tarafa yapışmazken çoğunlukla sepet kenalarında kahve yapışıyor. Tüm bunlara rağmen güzel bir sepet. Fakat Wafo veya Weber tarzı sepetlerin performansını beklemek büyük bir hayal kırıklığı yaratabilir...

The coffee taste great. I find with the beans I use I'm dosing this basket closer to 21g to fill the basket, at 20g my puck is soaking wet... I'm going to get a smaller version because I want a pound of beans to last longer and dose closer to 17-18g. Your milage may vary with the beans you use.

The IMS Big Bang 58mm basket has quickly become one of my favorite upgrades for espresso. What stands out most is its consistency - shot after shot, the extraction is even and predictable, which makes dialing in much easier and far less frustrating. The precision of the basket design really shows in the cup. I’ve noticed improved clarity in flavor, with balanced extractions and fewer channeling issues compared to standard baskets. It’s also a bit more forgiving, which is great whether you’re experimenting with new beans or just trying to get your morning coffee right without overthinking it. Build quality is excellent, as expected from IMS. The finish is clean, and it fits perfectly in a standard 58mm portafilter. Overall, it’s a simple upgrade that makes a noticeable difference - highly recommended for anyone looking to improve consistency and quality in their espresso.

Excellent quality, reliable and consistent
