# Bottling
and Tirage **By Simon Wren** ยท 2022-06-22 Tirage: a frantic, theatrical and intense period in any sparkling wine producer's year. ![](//cdn.shopify.com/s/files/1/2193/2489/files/adrian-preparing-the-wine-min.jpg?v=1655825773) _Adrian preparing the wine._ To explain what tirage is, we need to start at the beginning: harvest. After we have picked and pressed the fruit, the juice for our sparkling wine is fermented in tank to create a still base wine. During tirage (which usually takes place around June), the wine is bottled, and a mixture of wine, sugar and yeast is added to each bottle to create the chemical reaction which traps carbon dioxide in the bottle to produce the fizz. Unlike tank fermented sparkling wines, traditional method's ubiquitous bubbles are always made this way. ![](//cdn.shopify.com/s/files/1/2193/2489/files/dani-preparing-bottles-with-the-ioc-min.jpg?v=1655825773) _Dani preparing bottles with the IOC._ ![](//cdn.shopify.com/s/files/1/2193/2489/files/empty-bottles-queing-up-to-be-filled-min.jpg?v=1655825773) _Empty bottles queing up to be filled._ ![](//cdn.shopify.com/s/files/1/2193/2489/files/ioc-visit-us-annually-for-tirage-with-their-beautiful-machine-min.jpg?v=1655825773) _IOC visit us annually for tirage with their beautiful machine._ Placed under crown cap, the bottles are then laid down for anything from 18 months to ten years. And it's not only the fizz which develops now - the yeast cells impart their magical biscuity, nutty flavours to the wine, too. ![](//cdn.shopify.com/s/files/1/2193/2489/files/once-full-these-bottles-will-be-stacked-in-cages-in-a-temperature-controlled-store-min.jpg?v=1655825773) _Once full, these bottles will be stacked in cages in a temperature controlled store._ ![](//cdn.shopify.com/s/files/1/2193/2489/files/orson-filling-a-cage-min.jpg?v=1655825773) _Orson filling a cage._ ![](//cdn.shopify.com/s/files/1/2193/2489/files/the-bottles-have-to-be-picked-and-laid-in-the-cages-at-a-frantic-pace-min.jpg?v=1655825773) _The bottles have to be picked and laid in the cages at a frantic pace - usually there is a minimum of 4 of us working at the end of the bottling line._ ![](//cdn.shopify.com/s/files/1/2193/2489/files/orson-dons-ear-defenders-the-machinery-is-deafening-min.jpg?v=1655825773) _Orson dons ear defenders - the machinery is deafening!_ ![](//cdn.shopify.com/s/files/1/2193/2489/files/the_bottles_are_laid_horizontally-for-anything-up-to-10-years-before-disgorging-and-releasing-min.jpg?v=1655825773) _The bottles are laid horizontally for anything up to 10 years before disgorging and releasing._ At the last stage (which won't happen to these bottles for about three years), the lees are removed, dosage (a solution of sugar and wine) is added and the crown cap is replaced with a cork. Finally, we leave for 3-6 months under cork before release to allow the dosage to integrate fully. --- > Source: [Westwell Wine Estates](https://www.westwellwines.com/blogs/journal/bottling-and-tirage)
