In December 2016, in a collaboration with the Belgian specialty store Tasttoe Two, 3 Fonteinen released 150 gift packs (75 available at the brewery and 75 available at Tasttoe Two) called "The Perfect Date" which contained one bottle of the first batch of Zenne y Frontera, one bottle of Bodegas Tradicion Oloroso (30 year Sherry), and one bottle of Bodegas Tradicion Pedro Ximinez (20 year Sherry). The price was 195 euro.
The second batch of Zenne y Frontera is limited to approximately 3,000 bottles. This batch contains lambic that has been in the barrels since the spring of 2013 as well as younger lambic that had been used to top off the sherry barrels that were not fully emptied in a type of Solera method. The average age of lambic in the second bottling is more than 45 months.
In March of 2017 the brewery received 21 more Oloroso sherry and 9 more Pedro Ximénez sherry barrels.
