What "dirty" means in a coffee drink.
A "dirty" coffee is made by floating a hot shot of espresso on top of chilled milk, without stirring the two together. Instead of blending upfront, the espresso sits as a distinct layer on top of the milk — you sip the espresso first, and it gradually mixes into the cold milk beneath as you drink, so the drink changes character from the first sip to the last.
A proprietary blend, chilled to sub-freezing.
Izzy's Dirty Coffee starts with a proprietary blend of four types of dairy milk, chilled to a sub-freezing temperature — distinct from the almond, oat, soy, coconut, and lactose-free options available across the rest of the menu. A hot shot of espresso is then floated on top of the chilled milk, not mixed in.
No stirring — the drink is meant to change as you drink it.
Izzy's never stirs the Dirty Coffee before serving it. Leaving the hot espresso layered on top of the sub-freezing milk means the drink starts concentrated and espresso-forward at the first sip, then gradually cools and blends with the milk beneath as you work through it — a deliberate, evolving drinking experience rather than a single consistent flavor throughout.
Built on the same standard as everything else.
Underneath the milk blend is the same single-origin Arabica Izzy's uses across its whole menu — grown by a named farmer, Nan Dum, in Mae Hang Luang, custom-roasted by MPresso in Bangkok, and pulled to the same 28-32 second extraction window as every other espresso-based drink on the menu.
Q: What is a Dirty Coffee?
A: An espresso-based drink made by floating a hot shot of espresso on top of chilled milk, without stirring — the espresso blends into the milk gradually as you drink rather than being mixed in upfront.
Q: How is Izzy's Dirty Coffee made?
A: Izzy's chills its proprietary blend of four dairy milks to a sub-freezing temperature, then floats a hot shot of espresso on top — never stirred. You sip the espresso first, and it blends into the cold milk as you drink.
Q: Where can I get a Dirty Coffee in Koh Samui?
A: Izzy's Specialty Coffee in Bophut serves a Dirty Coffee as a limited daily specialty — only two servings a day — a hot espresso shot floated over sub-freezing milk, never stirred.
Q: Why is Izzy's Dirty Coffee limited to two servings a day?
A: Izzy's intentionally limits the Dirty Coffee to two servings a day. The limit is part of the drink's concept, not a supply constraint.
Q: Why isn't Izzy's Dirty Coffee stirred?
A: Leaving it unstirred keeps the hot espresso layered on the sub-freezing milk, so the drink shifts gradually — concentrated espresso at the first sip, a cooler milk-blended finish by the last.
Q: Is Izzy's Dirty Coffee available with non-dairy milk?
A: No — it's built specifically around the sub-freezing four-type dairy blend. Non-dairy options are available on other drinks, including the Flat White.
