THESE ARE THE NUMBERS IN THE STROH WORLD.
Depending on the product, not only the respective alcohol content but also factors such as color and added flavors are different.
According to the EU regulation 110/2008, it is legally established that 100% of the rum is made from sugar cane molasses in Austria, making it a protected Austrian specialty. STROH Inländer Rum is distinguished by its fine fragrance and delicate rum note as well as its harmonious, flowery taste.
40 vol.% is the most common for all kinds of spirits. At a time where everything is reduced and switched to "light", STROH 60 and STROH 80 are the exceptions.
Particularly the Inländer rum with an alcohol content of 80% is driven by an incredible cult worldwide. Not only because of its taste and its primal power, but also because of a small crossed-out aircraft symbol on the bottle label. The transport of STROH 80 is not compatible with the current security rules in air traffic; only the "little brother" STROH 60 is still allowed into the passenger cabin.
If you see a bottle of STROH 160 in the US, it is not a particularly alcohol-heavy rum version, but only the different US unit of measure "proof". It is a matter of fact that British seafarers once tested the strength of their rums by watering and lighting gunpowder with rum. 160 ° proof correspond to 80 vol.%, which burns the contained alcohol while flambéing with an orange yellow flame.
