It is definitely not oak... not heavy or dense enough. Here is an image of a freshly cut piece. The beam it came from was said be over 100 years old.
I didn't think about chestnut. It does have a blonde color when cut, and a honey tone when boiled linseed oil is applied to the freshly exposed wood. The red and dark tints on the piece above are what happens when I take a draw knife to the aged surface.
If it has whipped cream and chocolate drizzles on it, it’s dessert. Grow up and get a coffee damnit
