What is the typical IBU range for a Flanders Red?

Flanders Red Ale typically has an International Bitterness Units (IBU) range of 10-25. This style is characterized by its balance between malt sweetness and sour acidity, which emerges from the fermentation with specific yeast strains and often the addition of lactic acid bacteria. The bitterness level of 10-25 IBU is relatively low compared to many other beer styles, allowing the complex flavors of tartness, fruit, and subtle oak to come forward without being overshadowed by intense hop bitterness.

The purpose of a moderate IBU range is to complement the malt-forward character and enhanced sourness rather than compete with it. Higher IBUs, like those in the upper ranges (30-40), would overpower the delicate balance typical of a Flanders Red, while ranges below 10 might result in a beer that lacks sufficient bitterness to provide balance. Thus, the range of 10-25 IBU is ideal for maintaining the integral flavors that define this traditional Belgian beer style.
