The single vessel brewing process may lend itself to a small amount of grain passing through your basket and entering your kettle. In our testing, we found 2% or less of ‘grain pass through’ to be typical on brew day. To put that in perspective that is roughly 6oz of grain for a 20lb recipe.
If you are seeing more than 2% of your grain passing through your basket and into your kettle, here are a few tips.
- When mashing in (adding your grain to the basket/water) keep your pump and heating element off for the first 5-10mins. This will allow the grain to fully hydrate. Once fully hydrated the grain is larger and less likely to pass through the filter at the bottom of your grain basket.
- Double check your crush. We recommend a .035” crush. Anything finer will allow grain to potentially pass through the filter in the grain basket
