I'm glad you guys enjoyed my pre-burr review on the Gorilla Gear burrs... The correct and appropriate use of language is important even when used inappropriately..in Blazing Saddles the Movie Hedley Lemarr the assistant to the Governor said to Sheriff Taggart after a spectacularly florid and OTT speech, 'why Mr Lemarr you use your tongue prettier than a $20 whore'. Impressive stuff, modern poetry...suck on that Shakespeare is all I can say. I'm showing my age too. Mazzer Robur burrs have a reputation for taking 20kg and then some of beans to be bed in. It turns out that this was caused by Mazzer producing poorly machined burrs, one engineer in the CoffeeSnobs group took photos of the rough edges and poor finish obvious to even the naked eye. The cause was thought to be equipment that did the cutting being blunt. Evidently Mazzer fixed this....evidently. The corollary of this is that Mazzer burrs are often not the first choice for burrs in the Robur. My Robur has aftermarket burrs fitted by Espresso Works here in Perth and it was for a first line cafe use as their main machine so obviously they did it for reasons other than cost as the difference in cost is not that much, less than $100 maybe even less than $50. I want to replace the burrs just in case even though by my calculations at 20kg per week since January the burrs should still be in good shape and the machine has been not used since July when they started using their Mazzer Kold. There are also burrs called Food Friendly Burrs supposed to last 70% longer. Thoughts?
