New to brewing and seeking confirmation. I followed a blackberry and elderberry wine recipe from Andy Hamiltons booze for free book. It states to add all the ingredient together camden, yeast, nutrient etc in one go. However, I have then read that the camden should be left to work first before adding the yeast. Obviously I am now confused. Do I need to add more yeast as the camden tablets Killed the first lot or do I leave it to see what happens. Any advice would be great. Thanks.
