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

For a couple of bucks more, you can get an IMS Big Bang basket! Why is it better? It’s made by IMS, one of the best espresso basket makers (look it up on Wikipedia). The sides and bottom of the baskets are flat making them a tighter fit in your portofilter, the holes are uniform and cut even for a better flow. These are the real deal - competition grade. Every new espresso machine should come with an IMS Big Bang basket, old machines too!

Works as described, easy to remove from the portafilter and clean. Easily holds 18 grams of coffee.

Such a great basket! Easy to clean as usually my puck leaves no residual grounds in the basket. I feel as if my shots are more consistent based on the reduction in channeling that I am witnessing. My only complaint is that my magnetic dosing collar doesn’t really stick to this basket which can be a pain. I sorta just hold my collar on with my thumb while dosing to keep it on there

While cleaning my Isomac Millennium (E61) I decided, after 20 years of use, to try one of the puck screens folks are using these days. The puck screen on the Millennium is not at all easily removable so cleaning it well is a real pain involving tons of backflushing. When the puck screen came, I realized it wouldn't fit in the tapered OEM basket, so that led me down the path of getting a new basket with straight walls that would fit my portafilter. I'm happy to say that this basket fits perfectly in my portafilter and also accepts my 58.5mm puck screen (which does indeed help a lot with the grouphead screen staying clean). My espresso is also notably sweeter, though I'll have to spend more time with this basket before I can say it wasn't due to my latest cleaning. I did have to grind a bit finer with this basket, so I would expect some impacts to flavor. My tamper is 58mm, so it does leave a few fines around the edge, so I'll probably upgrade my tamper to 58.5mm next. Overall, the basket seems well made, looks cool if that's important, and my espresso tastes great.

This basket is a good, general purpose basket that's good at creating "pretty" shots with the classic rat tail visual, due to its unusual hole distribution. It's also (purposely) not a high flow basket, so it's good at doing flow profile shots or darker roasts. It fits a variety of portafilters, and is easy to clean. A great basket if you need the features.

I purchased this basket for use with a Gaggia Classic Evo Pro. Right now, this is a mostly stock unit (no adjustments to the OPV, no PID) and the only modifications performed has been switching from the stock shower screen to an IMS GA200IM and the use of a bottomless portafilter. Compared to stock baskets, the big bang offers a number of advantages. First, this is a straight wall basket which I definitely prefer over the curved basket included with my portafilter and the unit itself. For dialing in, this was relatively easy and only took 5 adjustments on grind to get a very workable and consistent extraction. In terms of flavor, it does seem to offer a different level of extraction than possible from the traditional "competition" straight wall basket, but seems a lot easier to dial it in. I forsee this will become particularly useful when trying new coffees, as it is certainly frustrating to go through 20% of a 12oz bag of coffee just to get the grind dialed in.

Compared to the two OEM filter baskets, one coming with the Espresso machine and one coming with the bottomless portafilter, this IMS Big Bang is definitely the best that I can tell visually from the espresso extraction through a bottomless portafilter. Less but finer grounds help as well.

This basket is one of my daily drivers for both of my espresso machines. It enhances fruit notes and brightens espresso from natural and other dry process beans. It allows for finer grind and still maintain proper water flow. Very easy to use; just snap it into your portafilter and go at it. Cleaning is a breeze as the holes don't get blinded after pulling a shot. Other high efficiency baskets suffer from that, and often require use of a bottom filter to help with cleaning. This one doesn't have that problem. Only down side I see is that it is not magnetic, so if you use a funnel, you have to be careful not to knock it off while attaching to grinder holder or when transferring grounds into it. This makes it 4 star in my book.

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...

Holds 20gs no problem even with a puck screen. Flow will be quicker then standard filter baskets. As advertised. Fits great 'no ridge" in my E61 and knock out clean is much better getting that spent puck out. Yep works better "less squirting" with bottomless porta. Enjoy!

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.

Excellent quality, reliable and consistent
