Cubes of Chestnut wood from trees in southern Germany.

Disinfection:
We recommend leaving the cubes and chips to soak in brandy for a few days before adding them.
There are several options here, try to find something that you think suits the finished result.
You can also put them in the oven, but be careful, as too high heat and/or too long a time in the oven can change the properties of the cubes. 90 degrees for 5-8 minutes is recommended.

Contact time and quantity:
There is no definitive answer to this. Beer style, storage and your own taste preferences come into play.
Chips can be stored for 3-7 days, and cubes for 1-6 months. Taste as you go.

This is what the supplier writes:

Chestnut wood , somewhat sweet and fruity with a strong color release!
However, it is not dominant and is only used to supplement depending on what you intend to use it for!
