- LB1 is a kettle-souring bacteria that respects the yeast flavor expression
- Selected specifically for its ability to provide a precise acidity related to the combined production of lactic and acetic acids
- Recommended for Gose, Berliner Weisse and other balanced sour beers
- Fermentis active dry yeast offers reliability, ease-of-use, and consistency to home and professional beverage makers across the world
SafSour LB 1™ is an excellent choice for producing consistent, repeatable Goses, Berliner Weisses and other sour ales. A heterofermentative lactic acid bacteria (L. brevis), SafSour LB 1™ has been selected by Fermentis specifically for its ability to provide a precise acidity related to the combined production of lactic and acetic acids. SafSour LB 1™ also reveals a neutral aromatic profile, respecting the aromatic signature of the yeast in the final product.
- Acidifies non-hopped wort within 30h–48h at a temperature of 89.6°F +/- 9°F (32°C +/-5°C) .
- As a heterofermentative lactic acid bacteria, SafSour LB 1™ produces lactic acid and acetic acid.
- SafSour LB 1™ presents a low tolerance towards iso alpha acids (half of growth is inhibited, IC50 of 10 ppm).
- Typically reaches a final pH of 3.6–3.9
Usage:
It is recommended to pitch directly into the non-hopped wort at the temperature of 32°C (+/- 5°C).
An oxygenation rate of 13 ppm helps achieve a balanced acetic/lactic profile.
Dosage:
The optimum dosing rate is 10 g/hL
