A groin-high label cupboard seen and photographed in the Sonnema (previously Sommema/Plantinga) distillery. Definitely also from the Plantinga side of things. Second drawer from the top: Left and right Plantinga Dubbel Gebeide Jonge Jenever (Doubly Abided Young Gin); third drawer from the top something unknown (to me) from Sonnema; fourth drawer from the top left Plantinga Beerenburg, right something unknown (probably "Dubbel Gebeide Jenever from some or other brand); fifth drawer from the top left Plantiac bottle neck star labels, right unknown; sixth drawer from the top left Plantinga Citroen Jenever (Lemon Gin), right some sort of bottle neck label; seventh drawer from the top left and right Sonnema Citroen Jenever (Lemon Gin); eighth drawer from the top left Plantinga Advocaat (Eggnog), right something Plantiac-related; all lower drawers something Plantiac-related.
The box containing 12 200 cc bottles looks rather Spartan. This one is also from December 2015. The production code, which is a regular feature on the caps of all bottles since 1991 (and probably earlier) is written large on the box here.
Since 2004 (when Plantiac production at Boomsma started), decoding works as follows:
L = Alway an "L", indicating that this is a grocery item
YY = The last two digits of the year
BBBB = Batch number
DDD = Xth day of the year
HH:MM = Production time
So the bottles in this box were bottled on the 72nd day (14 March) of 2015, at 13:45.
