You can. Buyers who are nearby, or who are coming to a depot anyway, collect in person by arrangement, and there is no shipping charge on a lot that never travels.
There is one thing to know before you drive over: a bottle collected here carries Dutch excise duty, even if you are taking it straight back to Germany or considerably further. The moment it leaves our premises it has entered the Dutch economic area, and customs have no way of knowing whether it stays here or goes with you. The Dutch rate is what has to be declared and paid, and that is not something we can waive on request.
If the destination rate would have been lower, having it shipped rather than collected is usually the cheaper route. The calculator on our excise page will show you both figures before you decide.
If you would rather send your own courier, we will pack the bottles to the same standard for a flat € 4,00. From the moment they leave with somebody else's driver, though, the journey is not ours to answer for — and the same Dutch excise rule applies, because the bottle still left our building on Dutch soil.
