Flitspopper is a bold collaboration between Gulpener Bierbrouwerij and Oedipus Brewing: claimed as the world's first Sour Eisbock blend. Gulpen's independent family brewery, brewing since 1825, embraces experimentation and creative risk.

At 7.5% ABV, Flitspopper marries the rich, malty foundation of an Eisbock with crisp acidity. The result is a layered beer where sweetness, sourness and bitterness coexist in deliberate tension. This is a thinking drinker's beer—complex, challenging and rewarding.
