Alvinne Sigma is a dark and strong beer that impresses with its skillful balance of sweet and sour flavor notes. As part of the "Omega – Phi – Sigma" trilogy, Sigma matures in stainless steel tanks, where the unique Morpheus yeast develops a refreshing acidity. This beer strongly resembles the traditional Flemish Oud Bruin but stands out with its robust alcohol content of 8%. Alvinne Sigma offers a rich and complex taste experience that delights both connoisseurs and lovers of strong beers.
