'Liquoring back' in vessel

If liquoring back in vessel (adding water to adjust volume and ABV) is part of your production process, you could choose to have this reflected in the drink's recipe in Breww. This will serve as a call to action, and the volume addition can then be actioned on the batch.

Adding Liquoring Back Actions to a Recipe

• Fixed amount per batch: Add an “Add water” action to your recipe specifying the exact volume to be added. It is worth noting that the amount called for on the recipe will automatically scale if scaling is enabled when starting the batch.
• Variable amount per batch: Add a “Reading” action with Volume selected. While this is a 'reading' action, this option allows you to manually enter the 'volume' amount you have calculated to liquor back by on the brew sheet.

Increasing Vessel Volume

To actually increase the vessel volume in Breww, head to the batch and use: Actions → Add liquid/volume.

Once added, the liquored-back volume will be reflected on the vessel and increase the available volume for racking.

Impact on ABV

• Liquoring back (increasing the vessel volume) doesn’t change the batch’s calculated ABV in Breww.
• If your standard process includes liquoring back, the advertised ABV set on the drink/beer should already reflect the final ABV.
• When using the “Advertised ABV entered on the beer” option for duty, Breww uses this value for duty calculations—not the ABV from fermentation readings.
• So, you don’t need to adjust anything for duty. Your batch ABV will still reflect readings taken before liquoring back, but duty will be based on the advertised ABV set on the drink/beer.

Adjusting ABV After Liquoring Back

If you don't have **Advertised ABV entered on the beer **as your default for duty, and instead, analysis readings are being used:

1. Go to Actions → Edit batch details.
2. Change the ABV calculation method to **Advertised ABV entered on the beer **or Entered manually.
3. This will mean that the advertised ABV is used, or you will need to enter the correct ABV value manually.

Handling a batch that is over- or under-fermented, which you plan to sell as a different product

If a batch over-ferments, you may choose to liquor it back (as described above) and still sell it as the standard product.

Alternatively, if it falls outside your spec—whether over- or under-fermented—you might decide to sell it as a different product instead.

To do this, you can use a derived in vessel or derived at packaging beer. These allow you to create new products under another beer name that are still linked to the original beer, but ensuring correct ABV declaration on labels and for duty.

Which option to use depends on your process:

• Use derived at packaging if you’re packaging the out-of-spec beer straight away from the batch.

• Use derived in vessel if you’ll hold it in vessel longer or are making further changes in vessel first.
