What are common techniques used by vodka producers after distillation?

The common techniques used by vodka producers after distillation often include passing the spirit through activated charcoal and adding texture additives, which is why this option is correct.

Activated charcoal filtration helps to remove impurities and any remaining congeners, which can lead to a smoother, cleaner product. This process is important because vodka is typically characterized by its purity and neutral flavor profile. The use of texture additives can enhance the mouthfeel of the vodka, making it more pleasant to drink. Vodka producers may experiment with different levels of filtration and the use of additives to achieve their desired style and quality.

In contrast, adding fruits and spices is commonly associated with flavored spirits rather than traditional vodka, which is intended to be pure and neutral. Direct bottling without filtration would generally not be a standard practice for vodka since it may result in a less refined product. Lastly, filtration without any additives may not adequately enhance the texture or mouthfeel of the vodka, which is a key factor for many producers aiming for a high-quality spirit.
