Why do the outer walls of ageing rooms turn black?
This discoloration of the walls is a typical phenomenon in all distilleries where spirits are maturing. Due to the maturation in barrel, part of the spirit exudes, this is also called the angel’s share. An alcohol fungus feeds on this, and it is that fungus that settles on the walls and gives a typical black colour.
This is certainly not a harmful mould, but it is a very typical aspect of a distillery where spirits are maturing.

What is malt wine?
Malt wine forms the basis for genever & whisky.

What is a Sherry barrel?
Sherry barrels are barrels previously used for ageing Sherry (a fortified wine produced exclusively in Spain) and are made from European oak.
What is a Bourbon barrel?
Bourbon barrels are barrels that have previously been used to mature American Bourbon whisky and are made from American oak.
What are the biggest differences between a Sherry barrel versus a Bourbon barrel?
Bourbon barrels (American oak) are a lot more porous, so that the positive flavors are released relatively quickly. At Filliers Distillery these barrels are used for the maturation of the unique Barrel Aged Genever range.
Sherry casks (European oak) are a lot stiffer, so the flavours are released a lot slower. At Filliers Distillery these barrels are used for the maturation of the Single Malt Whisky.
Finally, Sherry casks are extremely scarce as they are only available in the Xeres region in Spain, the only place where Sherry is allowed to be made. This is a stark contrast to Bourbon barrels that are available all over America.
How many barrels are used for ageing at Filliers Distillery?
The distillery currently has 5,000 barrels and thus has one of the largest maturation capacities in Belgium, the Netherlands & Luxembourg.
What is new spirit?
Distillation is done at least twice during the process. After the first distillation, a new spirit is obtained. This is not yet drinkable as the heart of the alcohol is not yet separated from head and tail.
Where does the terminology head, heart & tail come from during distillation?
After the first distillation, a new spirit is obtained which is distilled a second time. In this process the head and tail are separated from the heart of the spirit. This is done to remove harmful parts from the alcohol in order to continue working with the pure product.
Why does Filliers Distillery distill in copper?
Copper is not only an excellent heat conductor, but also ensures that harmful microscopic particles are broken down during the distillation process.
How is Belgian Advocaat made?
Filliers Distillery still follows the authentic recipe of Julia Denecker, the wife of Firmin Filliers (3rd generation) who introduced the recipe in 1970. This Belgian Advocaat is still traditionally prepared “au bain-marie” with fresh eggs and milk.
What is the difference between genever and whisky?
genever is a grain distillate whose raw materials are grains (malt, wheat, rye,…), water, a mandatory percentage of juniper berries and in some cases grain alcohol.
Whisky, on the other hand, is only made from a grain distillate based on one or more grains (sprouted & dried barley, rye, wheat, …) & water.
During the production process, the mash is filtered for whisky before fermentation, which is not the case with genever.
Finally, it is mandatory for whisky to allow the spirit to mature for a certain time in wooden barrels. This is not mandatory for genever.
