Recipe/batch volumes

When it comes to producing batches in Breww, you will come across the familiar concepts of recipe and batch volumes as well as expected wastage, but what do these represent in Breww? Here's a quick overview of these terms and how they are used in Breww.

It's important to ensure that your recipe and planned batch volumes are consistent to get accurate reporting data. This will also ensure that the correct ingredient quantities are added to the batch when scaling your ingredient additions if you are brewing a differing batch volume to your recipe volume. You can read more on scaling in Breww in the Batch ingredient scaling help guide.

In Breww, we consider the recipe volume and batch volume to mean the volume you expect to collect in your primary vessel, for example, a fermentation vessel. You may have a recipe written, for example, where you expect to have 2,000 litres collected in the vessel. This, therefore, should be entered as the batch size on the recipe. If you then plan to brew a batch of this batch size, this should be entered as the batch volume when creating a batch. Depending on your scaling settings set in Production settings or if you selected the Scale recipe quantities to match batch volume checkbox when starting a batch, then if you were to enter a batch size of 4,000 litres, then the recipe quantities entered on your recipe (written for 2,000 litres) would automatically be scaled, and in this example double; this allows you to have a single recipe which you can use for any volume being brewed.

When you come to transfer your batch from the brewing system to your primary vessel, you will be able to enter the actual volume to transfer; depending on your extract efficiency, you can choose to enter less than the planned batch volume or more than the planned volume. If you have produced a larger batch size than expected, it is important that this is transferred to the vessel as you will only be able to package from the amount available, so this must be included in the initial transfer from your brewing system. Alternatively, if you have transferred the incorrect amount, you can add volume to the vessel by selecting Actions->Add liquid/ volume while on the batch.

Wastage refers to how much of the planned batch volume you expect to lose from the batch through batch actions such as transfers and packaging. For example, you may have a batch volume of 2,000 litres; however, you may expect to lose 5% of this batch. Therefore, you should enter 5% of 2,000 as your expected wastage volume of 100 litres.
