IMS Big Bang Precision Filter Basket for 58mm portafilters, 18-20g. double espresso (h23.5)

This basket is excellent quality. I've had two of them for over a year. Dialing in espresso effectively is all about eliminating as many variables as possible. These baskets deliver that in spades. They're also super easy to clean and they fit in my portafilter perfectly.

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!

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.

I have a number of espresso baskets--IMS, E&B, Big bang, baristapro.... If you want a true classic style of espresso, then this is the basket you want. It focuses on crema and gives you a Nice, full body mouthfeel--The only thing that comes close are the newer 58 mm to 49 mm step down baskets. Additionally, it gives you a big sweet spot when you're making espresso. In other words, if you have an issue with your grind or your puck prep it's not going to matter so much. I believe this basket has 580 holes versus a standard IMS basket that has 710.

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

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.

Works well. Does not have nano tech coating so puck does stick a little when knocking out.

I was so looking forward to having a quality filter basket. After looking at which ones were better than the average, this one stood out to me. Using it, however, was a challenge. It is first a filter basket WITHOUT a ridge. Which means that it is held in place by friction only. The first few times of use I had to 'fish' it out of the garbage when emptying the coffee puck. I then used a knock box (not a good one by the way) I had the reverse situation. Getting the coffee puck out of the basket. It took some thinking, but I managed to get it to work or work good enough to use on a daily basis. The other issue was, if you are into serious coffee making and grinding your own coffee, you will have to play with the grinds to get the right consistency where it is not too fine that the water will not pass through or too course where it comes out like a waterfall. Again, a few trial and errors I managed to get it just right. But that was for one type of coffee. The next package took that same process. The basket was the issue with the holes, which was what this was designed to do. Overall? This is, as the literature attests too, is a great precision basket and well worth having it. The one star down grade is because of not having the normal ridge, but that's about it. I was told that a filter or filter paper will help, we'll see should I decide to get one.

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.

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.
