Vienna Roast

Vienna Roast is the name applied to a segment, the same level of dark roasting as the coffee beans. With the Vienna Roast, the beans will undergo a second crack and are removed at a temperature of about 230°C (446°F). If it grows in roasters, the seeds will quickly reach the French Roast (at about 240°C) and the Italian Roast (at about 245°C). Typical Viennese Roast Brazilian Coffee at 230°C To make it easy to visualize, we will classify roasted coffee relatively according to the following three levels of roasting: …

Very Dark-Brown Roast is only very bold, second only to the Italian Roast and behind the Vienna Roast (but generally still the Dark Roast). After the second explosion ended at about 240°C (464°F), the coffee beans were removed. With Very Dark-Brown Roast coffee beans almost baked black, the oil content on the surface is high; acidity is significantly reduced …

Instead of the drum's rotation (so it feels like they're boiling) while stirring them up to Because the Fluid-bed roaster does not have its cooling mechanism and instead relies on the built-in hot air blowing system (which turns off the furnace's heat source), the cooling …
