A glass tube with the exact diameter has been prepared.

The glass tube is divided...

... and the bottom of the bulb is closed off.

Now the glassblower blows softly until he gets the exact diameter...

... which has to be controlled. We accept only Versovino with 100ml content (+-5%).

The first step is done. Now he adds the other tube, puts on the corks, and assembles everything in our beautiful gift-box!
