Since 1870 we’ve lived and breathed malting. With this passion and expertise, and by combining traditional and modern techniques, we create an impressive range of malted and non-malted products, including several unique and exclusive barley malts.
There is nothing more we love than talking to brewers and distillers so if you have any questions, or would like to arrange a call with a member of our team, please feel free to get in touch – we would love to hear from you!

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.
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 grain’s total weight and is removed by milling to make brown rice which still has the bran and germ attached.
These hulls are treated with steam for sterilisation and removal of aroma. The final product is a suitable filtration aid for high naked grain grist percentage brews, to support an efficient runoff.
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.
The Rice Hulls that Crisp Malt supply have been assessed, and we can confirm that these were found to be completely flavourless and therefore will not affect your wort’s flavour profile. Instead, these inert fibrous hulls’ primary purpose 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).
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.
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.
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 Rice Hulls’ bulk density, 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. Therefore, we 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.
Now, this is the part we want to emphasise to you. Due to a considerable difference in Rice Hulls’ bulk density 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 pallet’s total weight 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.
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.
Flaked Torrefied Buckwheat is made by cooking buckwheat at high temperatures, which gelatinises the starchy endosperm, and ‘torrefies’ the grain.
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.
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.
Whatever the size, style and approach of your brewery, our maltsters are here to help. We’d love to hear from you, understand your malt needs and show how our malts can make all the difference to your beers and spirits.
