Grain Miller of Beer Brewing Equipment

Grain Miller is an important part in complete micro brewing equipment.
And how many rollers should you have? It depends on the beer you are brewing.

A double roller mill is your most basic type – and the cheapest price point as there is a stronger chance for smaller grains to slip through uncracked. You also have less control, as it’s more difficult to find the balance between fine grits and whole grains.
With a four roller grist mill, there are two points at which to control the crush parameters, it allows greater consistency and more control over the crush.
The first roller is set a bit wider, while the second is a bit finer, so you can pick up all the smaller grains, allowing tighter control over the composition of the particle size.
The grist acts as a natural filter for the wort to strain through. Different sizes are needed to ensure you get good lautering of the grist to extract sugars. The more sugar you can extract the better – as this means less malt is needed to reach your intended ABV therefore increasing your efficiency.
Basically – improved extract yield = more liters of beer!

How do you determine the optimum distance between the rollers? The ultimate measure is to assess the resulting particle size rather than the mill gap. The perfect level of grind can only be found through experience – and likely a few slow lauters.

How can you test the gap length? A feeler gauge or high precision calipers will get you in the ballpark. The feeler gauge will just give you a starting point – then the grist sieve will help the brewer dial it into perfection.
How can you test grist coarseness? A grist sieve? The best way is to use a series of pans with specific screen sizes to assess the amount of large and small grits all the way to fine flour.
Grist Sieves come in different sizes to suit your needs, with the standard sizes being 1.4mm, 0.6mm, 0.25mm. You would also need a pan to go under the stack of sieves and a cap to cover them. It is important to looking for a workable trade off between the fineness of the crush and lauter ability.
