Oude Mûre Tilquin à l’Ancienne has a chosen concentration of 35% (kg/l) fruit per liter of lambic. A total of 2,700 liters were produced for the first batch. Initially, 957kg of Loch Ness variety blackberries ([https://www.rhs.org.uk/Plants/75680/i-Rubus-fruticosus-i-Loch-Ness-sup-%28PBR%29-sup-%28F%29/Details Rubus fruticosus]) were placed in a 2,000-liter tank and topped with lambic until the volume of the tank reached 1,800 liters. Approximately 1,600 liters of lambic were obtained after fermentation and blended with 2 and 3 year old lambic for a total of 2,700 liters. Thus, the final fruit ratio is 35% (kg/l) fruit per liter or 957kg of blackberries per 2,700 liters of lambic.<ref name=TilquinBlackberryBlend> Facebook,Mûre Tilquin status update, January 2015, https://www.facebook.com/124028207655169/photos/a.639338152790836.1073741846.124028207655169/827636203961029/?type=1&theater </ref>
