The Forestry and Forest Products Research Institute, a public research center in Tsukuba, Ibaraki Prefecture, has developed a technique for producing alcohol from trees such as the Japanese white birch through fermentation using edible yeast. The new process does not require heating or chemical treatment, as has been the case in the past, and the trees give off a pleasant aroma. If researchers can confirm the alcohol is safe to consume, they will have created the world’s first alcohol from trees.

The stumbling block when making alcohol from wood is a component of the cell walls that hardens the tree but also prevents fermentation. To remove this component, the wood had to be heated, which meant it lost its aroma, and sulfuric acid — which is harmful to human health — had to be used. The undrinkable alcohol was used as fuel.


1) What species of tree is being used?


Japanese white birch.

2) What type of alcohol was being made from trees before?


Alcohol for use as fuel.

3) Why is heating the wood bad?


Because it loses its aroma.
