A few days ago I turned to ferment Oceanspray Cran-blackberry juice with Sarfale S-04 yeast. I took a gravity reading and the OG was 1.120. The ingredients are filtered water, cranberry juice, sugar, blackberry juice, natural flavor, citric acid, vegetable concentrate for color, and ascorbic acid. However, it's been two days and there hasn't been any activity in the airlock. One possibility is that the cranberry juice is too acidic for the yeast to ferment. But the bottle is labeled as only 15% juice, and yeast can tolerate a wide range of ph values, so I'm not convinced that that's the issue. Is there a problem with the yeast itself? Is it a temperature issue? My room sits at about 67-69 degrees.
