GigaYeast GB124 Saison Sour


GigaYeast GB124 Saison Sour is a blend of saison ale yeast and lactic acid bacteria that produces a sour beer with fruity esters and a touch of black pepper.

Lactic Acid Bacteria are inhibited by hops, high gravity and low temperatures. You can adjust sourness by increasing or decreasing these variables. More than 7 IBU, gravity above 1.050 or temps below 65 F will increase the time to sour or lead to reduced overall souring. Warmer fermentation temps will typically increase the esters and spicy phenolics of the saison ale yeast in this blend.

Recommended Temperature Range: 68 F to 80 F

After 14 days at 71 F in 1.045 OG sweet wort, pH 5.6

  • Apparent Attenuation: 78%
  • ABV: 4.5%
  • Final pH: 3.6 (100X acidification)
  • 1.5% lactic acid W/V
