When you’ve got a grist that’s high in naked grains there’s a good chance that it’s going to be tough to run off after the mash stand. Rice Hulls are a by-product of the rice industry and they can be added to a grist to provide a filter bed for the wort.

In the blog post we’ll look at how rice hulls are made for the brewer, what they do and how to use them.

Also, we have another new product that we want to introduce to you; Flaked Torrefied Buckwheat. We will explain the flavours, uses, and how to use it.

Let us introduce you the first of these new, exciting products: Rice Hulls.

WHAT ARE RICE HULLS AND HOW ARE THEY MADE?

Rice is a cereal grain and when harvested it has a husk or hull, similar to barley. The food industry doesn’t want the hull so it’s removed during initial processing. It constitutes around 20% of the total weight of the grain and is removed by milling to make brown rice which still has the bran and germ still attached.

These hulls are treated with steam for sterilisation and removal of aromas, and the final product is a suitable filtration aid for high naked grain grist percentage brews, to support an efficient run off.

HOW MUCH RICE HULLS SHOULD I ADD TO THE GRIST?

Rice Hulls should be dispersed throughout the grist for uniform filtration. Addition rate will vary between 1 – 5% by weight of the grist, depending on the content of naked oats, wheat or rye in your existing grist.

HOW WILL RICE HULLS CHANGE THE PROPERTIES AND QUALITY OF THE WORT?

The Rice Hulls that Crisp supply have been assessed, and we can confirm that these were found to be completely flavourless, and therefore will not affect the flavour profile of your wort. Instead, the primary purpose of these inert fibrous hulls is to improve wort clarity and run off times by encouraging a uniform filter bed. During processing, they do not absorb significant quantities of wort, and therefore yield will be unaffected.

Rice Hulls contain no additives or allergens (A Crisp Allergen Statement is available), are not GMO nor irradiated, and are compliant for contaminants against EU legislation (A Declaration of EU legislation compliance for contaminants is available).

HOW LONG WILL RICE HULLS LAST IN STORAGE?

Our Rice Hulls have a Best Before date of 1 year from the production date. This will be stated on our label fixed to the bag. Remember to store these safely, as you would a bag of malt. Check out our Malt Storage Guide here.

HOW LONG DOES A RICE HULL ORDER TAKE TO PROCESS?

For smaller quantities, where we have warehouse stock available, normal lead times apply. However, for larger orders where multiple pallets are involved, lead times could increase to 3 to 4 weeks.

HOW MUCH RICE HULLS CAN I ORDER?

Rice Hulls can be ordered either by the pallet or bag, however, only a maximum of 2 bags can be offered on a mixed pallet. We must stress that because of the bulk density of the Rice Hulls, and consequently the increased bag size, there will be differences to pallet heights. This is substantial for an entire pallet of Rice Hulls, hitting a height of 235cm, which is significantly taller than a standard pallet of malt.  We therefore suggest you consider handling and storage capabilities before placing an order for an entire pallet of Rice Hulls. Please refer to the following section for more information regarding this.

HOW ARE RICE HULLS PACKAGED AND DELIVERED?

Now this is the part we want to emphasise to you. Due to a considerable difference in bulk density of Rice Hulls to our malt, the Rice Hulls will be supplied to you in bags of 18kg, as opposed to the standard 25kg you would expect with malt. Even at 18kg, these bags are significantly larger than the 25kg malt bags.

Ordering Rice Hulls with a Crushed Malt Pallet

To start, let us take a look at how Rice Hulls will be supplied to you if you order Rice Hulls with a pallet of CRUSHED malt. The first thing to note is Rice Hulls will displace an entire layer of malt on a CRUSHED malt pallet, reducing the total weight of the pallet down from 1MT. The Rice Hulls will be stacked as one layer on top of the pallet of malt (this equates to a maximum of 2 bags). Depending on orders of either one or two bags, a pallet will therefore contain 37/38 bags of product (crushed malt only) as opposed to the standard 40 bags per pallet.

An order of one bag of Rice Hulls in addition to a crushed malt order will result in a pallet containing 36 bags of standard 25kg malt and 1 bag of 18kg Rice Hulls. The total weight of this pallet would be 918kg.

An order of two bags of Rice Hulls in addition to a crushed malt order will result in a pallet containing 36 bags of standard 25kg malt and 2 bags of 18kg Rice Hulls. The total weight of this pallet would be 936kg.

An entire pallet of Rice Hulls would be 24 bags of 18kg Rice Hulls, weighing a total of 432kg.

Hopefully the diagram below will provide you with more detail on how we will package and deliver Rice Hulls with a CRUSHED malt pallet.

 

Ordering Rice Hulls with a Whole Malt Pallet

Next, let us take a look at how Rice Hulls will be supplied to you if you order Rice Hulls with a pallet of WHOLE malt. Unlike for CRUSHED malt, for WHOLE malt, the Rice Hulls will be stacked on top of the existing 40 bags, increasing the total weight of the pallet by 1 or 2 bags of Rice Hulls depending on the order. A pallet will therefore contain 41/42 bags of product (whole malt only).

An order of one bag of Rice Hulls in addition to a whole malt order will result in a pallet containing 40 bags of standard 25kg malt and 1 bag of 18kg Rice Hulls. The total weight of this pallet would be 1,018kg.

An order of two bags of Rice Hulls in addition to a whole malt order will result in a pallet containing 40 bags of standard 25kg malt and 2 bags of 18kg Rice Hulls. The total weight of this pallet would be 1,036kg.

An entire pallet of Rice Hulls would be 24 bags of 18kg Rice Hulls, weighing a total of 432kg.

Again, we hope the following diagram will clarify how Rice Hulls are packaged and delivered with a WHOLE malt pallet.

 

We understand that this is a lot of information to take in, so please feel free to contact us should you require any more information or clarification.

Now it’s time for us to briefly introduce you to our second new product: Flaked Torrefied Buckwheat.

HOW IS FLAKED TORREFIED BUCKWHEAT MADE?

Flaked Torrefied Buckwheat is made by cooking buckwheat at high temperatures, which gelatinises the starchy endosperm, and ‘torrefies’ the grain.

HOW MUCH FLAKED TORREFIED BUCKWHEAT SHOULD BE ADDED TO THE GRIST?

Flaked Torrefied Buckwheat can be added to the mash up to 25% of the grist. Similar to our other Flaked Torrefied products, Buckwheat does not need to be milled, and can be added directly into the mash.

WHAT PROPERTIES DOES FLAKED TORREFIED BUCKWHEAT OFFER?

Crisp Flaked Torrefied Buckwheat offers a unique flavour profile of toasted nuts, balanced with subtle spice. Buckwheat can also promote head retention. Flaked Torrefied Buckwheat is ideal for use in Saisons, Golden Ales and Sour/ Mixed Ferm beers. Additionally, it can be used in conjunction with Extra Pale malt to achieve a Low Gluten beer.
