Pilsner malt dominates the grist though a portion of Vienna and/or Munich malt contributes color and complexity. Sometimes contains other grains such as wheat and spelt. Adjuncts such as sugar and honey can also serve to add complexity and thin the body. Hop bitterness and flavor may be more noticeable than in many other Belgian styles. A saison is sometimes dry-hopped. Noble hops, Styrian or East Kent Goldings are commonly used. A wide variety of herbs and spices are often used to add complexity and uniqueness in the stronger versions, but should always meld well with the yeast and hop character. Varying degrees of acidity and/or sourness can be created by the use of gypsum, acidulated malt, a sour mash or Lactobacillus. Hard water, common to most of Wallonia, can accentuate the bitterness and dry finish.
