Cantillon Super Gueuze

Description
Cantillon Super Gueuze is a standard gueuze using a different label for marketing purposes at several occasions over several years during the 80's. It consists of 1, 2, and 3 year old lambic and was bottled in 750 mL and 375 mL bottles. The term super does not designate anything different with this blend of gueuze, but instead was a marketing term inspired by an old commercial ad by Paul Cantillon found at the brewery. With lambic having a hard time to sell in the 80's, Jean-Pierre decided to use the term Super Gueuze to be original and boost sales.
Label
Label text translation:
"Artisanal gueuze from Brussels. Pure lambic (1, 2 and 3 years). All natural. No preservatives or chemical additives. No saccharine. Living, ageable beer. Store horizontally at cellar temperature."
The last paragraph on this label would literally translate to "Lay me back down on my side at cellar temperature." This would suggest that bottles were shipped or stored upright at the point of sale, and appears to be an invitation to the bottle's new owner to store it horizontally, at cellar temperature. To date, this constitutes the only known documentation of Cantillon suggesting horizontal storage of their products.
