Our beer has a refreshing taste and a rich fruity flavour, which is popular among consumers. Sour beer has a long history, originating in Belgium. Some famous beers include Lambic, G ü tz, and Flanders Red ale. In other parts of Europe, Berlin sour wheat and Gus from Germany are also very famous sour beers. The sour taste of sour beer is formed through two pathways: fermentation by bacteria to produce acetic acid or lactic acid. The second method is to add some sour fruits to beer to create a sourtaste. Traditional sour beer brewing relies on acid producing bacteria in the natural environment to brew sour beer, but the microbial composition in the natural environment is complex, difficult to control, and the fermentation cycle is long, which is not conducive to the industrial production of sour beer. Therefore, brewers prefer to use lactic acid bacteria or acid producing yeast to acidify wort and brew sour beer.
Angel Yeast has launched a new lactic acid bacteria product LP08 for brewing sour beer, which has the advantages of fast acid production rate, soft acidity, and low production of acetic acid and diacetyl.
Acid production rate of SourBeer LP08
SourBeer LP08 was fermented under the conditions of original wort concentration of 12 ° P, inoculation amount of 0.1g/L, and 37 ℃. After 10 hours of fermentation, the pH drops below 3.8, and the lowest pH can reach below 3.4, which can meet the brewing needs of beer with different acidity and acidity.
Acid production characteristics of SourBeer LP08
SourBeer LP08 | control 1 | control 2 | |
pH | 3.64 | 3.74 | 3.78 |
Complete acidification time h | 10 | 16 | 14 |
Total acidity g/L | 6.72 | 6.92 | 6.80 |
lactic acid g/L | 3.77 | 3.48 | 3.44 |
acetic acid g/L | ＜0.02 | 0.14 | 0.12 |
SourBeer LP08 has a fast acid production rate, which can greatly save wort acidification time and increase yield. The sour beer brewed by SourBeer LP08 has a soft and non irritating acidity due to its low acetic acid content.
SourBeer LP08 has low diacetyl content
When the content of diacetyl in beer is higher than 0.15mg/L, it will bring a diacetyl flavor to the beer. SourBeer LP08 has a diacetyl content below 0.02mg/L and will not increase the diacetyl content in beer.
