Bag in Box

It looks, tastes, smells, sounds and feels like cask ale...

but it's so much more:

  • Lasts for 3 months from racking date.

  • Easily stored due to the compact and sturdy design.

  • Is easily transported because it's smaller and lighter than a cask

  • The product(s) can be rotated before it has been used up as it remains sealed

  • Can be used inside or outside (may require additional equipment)

  • It never comes into contact with oxygen so doesn't develop 'off' flavours

1 Jolly Sailor Brewery Bag in Box Guide 2024



Real Ale + Bag in Box = Jolly Good Beer

So how does it all work?

After the brewing process has completed, Jolly Sailor wort (non-fermented beer) get served into a fermenter and left to sit between 18 and 22 degrees Celsius. Yeast is then invited to the party and left to gorge on sticky sweet wort for 4-7 days. 

Once our little yeasties have finished munching through their fermented feast we get delicious craft beer (yay!). But alas, now the yeasties are fat and full, they have eaten too much, outstayed their welcome and are lingering around for scraps. It's at this point we put the beer on chill to drop (or clear) them out turning the beer 'bright'. 

We then move all the beer from the fermenter into one of our racking tanks, where it continues to clear and drop out any remaining sediment.

Once we are happy that the beer in the racking tank has our, 'Jolly Sailor Brewery Seal of Approval', we then plan the quantities that we will put into cask and into bag in box. This allows us to reach as many customers as possible with the container that is right for them.

For bag in box, we decant the yummy beery goodness into a double lined food-grade bladder taking care to fill it all the way to the top without leaving any room for oxygen that would later spoil the beer. We then cap the bag with a push-and-squeeze style dispenser, seal up the box and it's ready to be taken away and enjoyed.

Our commercial customers (and some home users) often purchase a Vitop Connector from us and the beer can be drawn through a hand pull where it can be enjoyed creamy and with a head that laces down the glass as your drink it. As the beer is taken from the bag a vacuum is created and the bag shrinks to the volume of remaining beer keeping it free from oxygen until it's empty and everyone is merry!
