I bought a nanotech baristapro basket from IMS, hoping to see an improvement in my shot and a better tasting cup. The basket runs faster than my stock basket, meaning that I need to grind finer with the same beans. The difference between too fine and not fine enough, is very small with the baristapro, it’s way too unforgiving. I’m left judging the tamp pressure, to account for the aging of the beans, and missing the relative consistency of my old stock basket (I still have that of course, just trying to make this one work). The best cup I’ve had with the baristapro was ‘maybe’ better than my stock best, but not entirely sure (as beans change of course). I’m left now, having used it for a few months, frustrated at the inconsistency caused by the frequent channelling (something my old basket never suffered). I think the increased fine grind has itself actually added to the channelling - as the pressure to penetrate the finer puck forces channels, looking for the path of least resistance. If I grind more coarsely, the short is under-extracted and runs out in too short a time. Has anyone had consistent success with this basket?
My shots before the IMS were actually quite consistent, with little channelling if any, and I always enjoyed the coffee I made (more than many coffee shops in fact). I thought perhaps a better basket might improve things, and it was worth getting it, just to know. I’ll keep persevering (some beans are better than others with it) but ultimately, I may end up reverting to the old reliable basket.
