Coffee

Hmm let me try from memory:

• it is metal and glass.
• The metal base (quite heavy) makes a squealing sound against the glass portion when installing it. Some (like Hoffman) find it unpleasant; others find that the tactile experience outweighs the auditory experience, as it is very solid
• it has slightly different dimensions, which make the puck deeper
• slightly higher extraction
• in a 3 way test against XL and OG, he was able to identify the three brewers correctly and overall preferred the Premium, though that may just be a result of a careless brew
• the amount of microplastics one will ingest from an Aeropress is probably not significant compared to other sources, and the Aeropress microplastics aren’t identified as immediately harmful (i.e. BPA free)
• it’s kinda an expensive way to make the same coffee and trades a lot of the original Aeropress benefits (price, portability, durability) for a luxury feel. It’s glass; you won’t want to toss it in your bag like the OG.
