My list for espresso based:

• Italia, separate universe
• Belgium, very close to perfection
• Greece, the best cold coffee

• France, ok-ish
• Germany, muddy hot water
• Switzerland, tasty muddy hot water made of gold and diamonds
• Austria, battery acid mixed with fresh grass (lower temperature of roasting). Horrible, horrible coffee

For Greek/homebrewed style, no filtering included

• The cheapest Auchan brand in France - perfect!
• Croatian, fine if you drink it with milk
• Serbian, way too fine powder, bad texture if mixed with milk but perfect without

Milk for coffee

• Greek Delta milk - The Milk
• Slovenian "slatdka smetana", 35% fat :D smooth heart attack
