The filtration and filling of spirits are two of the late-stage processes a micro-distillery must consider before getting a product onto store shelves. The filtration process will determine everything from turbidity to aroma to the taste of your product. Filling methods will dictate how efficiently you can get your product into a bottle and to the public.
In this blog, we review the importance of both filtration and filling for your micro-distillery — and provide you with our in stock product recommendations.
The Importance of Filtration
The process of filtration will remove impurities while protecting the flavour and overall adding clarity to the taste, smell, and appearance of the final product. The filtration process can be broken down into two steps.
The distillate is clarified by removing everything from coarse dispersed solids to fine colloidal matter.
Visible turbidity (haziness/cloudiness) is removed. While there is a growing movement to leave turbidity in a product, turbidity is often associated with lower quality or a defective product in the mind of the average consumer.
The most frequent causes of turbidity are high concentrations of calcium, magnesium, and iron, along with the presence of turbidity-causing long-chain fatty acid esters. Interestingly, and somewhat ironically, despite low turbidity being preferred by consumers, they increase turbidity when adding unfiltered ice to their drinks.

Don’t overlook the importance of proper filtration for your spirit. Distilleries should do everything in their capacity to create a product that’s clear with relatively little turbidity, in addition to a consistent taste and aroma.
