So many comments confused, but the important part is that the yeast survived in the cold.

“Yeasts that are active at very low temperatures can offer advantages in different areas,” Sarhan says in the statement. “If fermentation is possible at room temperature or even at refrigerator temperatures, energy can be saved since no additional heating is required. Furthermore, the yeasts could also be active during transport, meaning they could contribute to fermentation already on their way to the manufacturer.”
