# Barrel ageing in Breww

Barrel ageing in Breww can be handled by creating 'Barrel' vessels in the **Production** section. This setup gives you full flexibility to manage, transfer, blend, and package barrel-aged beer.

## Create your barrel store

To organise your barrels, we recommend setting up a dedicated **vessel group **(e.g. "Barrel Store"). This is covered in more detail in our [Vessel groups](/docs/vessel-groups/ guide.

## Create a 'barrel' vessel

Once your vessel group is set up, you can create individual barrels as vessels:

- Follow our vessel creation guide [here](https://breww.com/docs/brewing-systems-and-vessels/#creating-vessels).
- Set the **Vessel type** to Barrel.
- Assign the vessel to your "Barrel Store" group.
- Enable **Show on production dashboard** if you'd like these barrels visible in your main production view.

## Transfers, blends & packaging

With your barrels set up, you can:

- **Transfer beer** into barrels for ageing.
- **Transfer between barrels or vessels** as needed.
- **Blend multiple batches** in a barrel.
- Use the **Derived in vessel** feature if the final aged product is a new beer (e.g. a blend or barrel-aged variant). This allows you to convert the contents of a vessel into a new derived in vessel beer which can then be packaged and sold.

  You can learn more about the *derived in vessel* process in our [Alias, derived & guest beers guide](https://breww.com/docs/alias-derived-and-guest-beers/).
