As a beer brewery equipment manufacturer, we have met many clients whole plan to purchase beer brewery equipment with a little bigger capacity than they really need at beginning of business. They may have plan to brew half batch or smaller batch with their beer brewing equipment at beginning. Then the question is: What should be considered when brewing smaller batch with my brewery equipment?
The main answer is: the spent grain bed thickness.
In craft beer brewing, the spent grain thickness better be controlled within a suitable range. Too thick grain bed is too hard to lauter smoothly while too thin to hard to get clear wort. theoretically speaking, the thickness at 30-40cm is best range for wort lautering, but in actual beer brewing, the thickness 25-45cm is also acceptable. Based on our beer brewing experience, it would be about 2 cubic metre spent grain being produced when using 1000kg malt. Then you can calculate based on your lauter tun diameter and how much malt you wanna use per batch.
Eg: If you wanna brew with 110kg malt based on lauter tun with inner diameter 800mm. After calculation the spent grain thickness would be at about 43.8cm. This thickness is acceptable for wort lautering.
