unlikely, i've used both my baratza forte and mazzer mini with the same results. perhaps my machine was picky with the 18g VST and flow seemed too fast even with 15lbs tamp pressure on calibrated tamper after a few days..
fresher beans have absolutely no problem with flow and taste though so i can only conclude its freshness related..
