Pros & Cons Side by Side

Chemex 6-Cup Classic Coffee Maker

Permanent collection in the Museum of Modern Art — design recognised as functional art
Thick Chemex filters remove oils for the cleanest, clearest cup of any manual method
Non-porous borosilicate glass absorbs no odours or tastes — pure coffee flavour
6-cup serves 2-3 people in one pour — the most social manual brew method
Under £40 — the most beautiful coffee brewing method at any price

Proprietary Chemex filters required — standard filter paper incompatible
Requires kettle and coarse-grind coffee — not self-contained like pod machines
Glass requires careful handling — drops at sink height typically crack the base

Keurig K-Supreme Plus Smart Coffee Maker

MultiStream extraction saturates coffee grounds more evenly than single-needle alternatives
78oz reservoir — the largest K-Cup reservoir reviewed, reduces daily refilling
Smart app enables scheduling, brew strength and temperature from your phone
Brew Hot or Iced mode makes over-ice coffee in one step
28,400 Amazon reviews at 4.5★ — the most validated US-origin coffee maker reviewed

K-Cup pod ecosystem — pods less premium than Nespresso Vertuo quality and more expensive per cup than filter
Less common in UK vs US — K-Cup pods require online ordering rather than supermarket availability
US-designed machine that works on UK voltage but is primarily marketed for American consumers
