Suitable brewhouse size to brew both normal and high gravity beer
We have gradually realized now that more micro breweries plan to brew beer with various gravity, some might ranges from 8 plato to 16 Plato. So at the beginning of the discussion with our clients, it is more necessary to learn the gravity range they plant to brew. The beer gravity relates to the deign of brewhouse, especially the lauter tun as the wort gravity is decided by the grain ratio, and the grain ratio directly effect the lauter process efficiency.
An efficient lauter is effected by three main factors: the mashing result, lauter operation and hardware. We are manufacture for beer brewing equipment, so here we mainly talk about the diameter design (one of the hardware factors).
Theoretically 30cm-40cm grain bed is an ideal range for an efficient lauter process. An over-thin grain bed can not get clear wort, and an over-thick grain bed will lengthen the lauter process or even get the lauter stuck.
PS: But some brewmasters told me that they actually also brew well with 25cm and 100cm grain bed. We still need to further collecting those information and will talk in future topics once we have enough information about them. If you have this kind of experience, we appreciated on your kind sharing.
So 25cm-40cm or 30cm-40cm is a theory range to bring people reference on designing the equipment. However as mentioned above, more micro breweries plan to brew beer with various gravity, some might ranges from 8 plato to 16 Plato. Then how we know the suitable diameter to meet this kind of large gravity scale?
Here is an example:
One of our client plan to brew in 1200L batch with 150kg-500kg grain scales for different beer recipes.
150kg-500kg grain ratio is quite a big range. It is very difficult to figure out a diameter of lauter tun to fit this large range of grain ratio. The only way is to find a balance that is close to this range:
We calculated the required grain weights in different tank diameters to be able to form 25cm grain bed minimum to 40cm grain bed maximum:
1300mm (standard size): 185kg-290kg (to form a 25cm-40cm grain bed)
1400mm (custom size): 210kg-340kg (to form a 25cm-40cm grain bed)
1500mm (custom size): 245kg-360kg (to form a 25cm-40cm grain bed)
1600mm (custom size): 280kg-450kg (to form a 25cm-40cm grain bed)
1700mm (custom size): 315kg-504kg (to form a 25cm-40cm grain bed)
If we brew more high gravity beer, then we can decide the lauter tun diameters from options of 1600mm, 1700mm.
If we brew more light beer, then 1500mm, 1400mm might be more suitable.
So yes, we should find a balance point from them.
