Jeff Verellen, a barista and roaster at Caffenation in Antwerp, Belgium, is working on prototype weights in Carrara marble, iron and stone to place on top of the [AeroPress] so that you don’t have to do the work of applying your own pressure.
‘The different weights will be used to time the pressing,’ he says. ‘Depending on the grind and coffee, there are different times and pressures needed to extract the most out of each different coffee. This is also to achieve consistency in a commercial setting … and also to save time. The marble also looks nice.’
— The AeroPress and its fervent coffee-loving fans. I’d buy those.
