What Is Vienna Roast Coffee?
A dark roast taken to the very start of second crack, where the surface just begins to shine. One step past full city, one step short of French.
Vienna roast is a specific point on the roast scale rather than a style or an origin: the moment second crack begins and the first sheen of oil appears on the bean. It is the last roast level at which sweetness and roast character are in balance.
Where it sits
Roast levels are usually described by their relationship to two audible events. First crack is the bean expanding and splitting; second crack, later and quieter, is the cell structure beginning to break down.
- City. Just after first crack. Origin character dominant.
- Full city. Later, just before second crack. Balanced.
- Vienna. At the very start of second crack. First oil.
- French. Well into second crack. Oily and smoky.
- Italian. Darker still, close to the limit.
The names are conventions rather than standards, and they are not consistent between roasters. Vienna is also sold as continental or light French.
What it tastes like
Bittersweet, chocolatey, and heavy in the mouth, with a caramel note from sugars that have browned without burning. Acidity is largely gone, which is the main reason people choose it.
Origin character is subdued but not erased. You will not taste the delicate florals of an Ethiopian at this level, which is why paying for a distinctive microlot and roasting it Vienna is a waste of both.
How to recognise it
Look at the surface. A Vienna roast has a faint, patchy sheen where oil has just started to migrate outward, not the wet gloss of a French roast and not the matte finish of a medium.
On old coffee this test fails. Beans go oily with age too, so a matte medium roast that has been sitting for months can develop a shine that means staleness rather than roast level. See oily coffee beans for how to tell them apart.
What to brew it with
It suits methods that reward body and forgive imprecision.
- French press, where the heavy body is an advantage.
- Moka pot, the classic partner for this roast level.
- Espresso, where it gives the chocolatey, low-acid shot most people picture when they think of espresso.
- Anything with milk, since it has the intensity to survive it.
It is a poor choice for a delicate pour over, which is designed to showcase exactly the qualities this roast level removes.
Common questions
How dark is a Vienna roast?
Moderately dark. It sits at the beginning of second crack, past full city and before French roast, with a light sheen of oil just appearing on the surface.
What does Vienna roast taste like?
Bittersweet and chocolatey with a heavy body, some caramel sweetness, and origin character largely subdued. Low acidity compared with lighter roasts.
Is Vienna roast the same as French roast?
No. French roast is darker, well into second crack, properly oily and distinctly smoky. Vienna keeps some sweetness that French roast burns off.
Does Vienna roast have less caffeine?
By weight, almost the same as a light roast. By scoop, slightly less, because darker beans are larger and less dense. Weighing removes most of the difference.
