So my braggot has been in primary for 9 days now. still airlock activity every 10 seconds. the OG was 1.0732. took a reading today and its 1.0611 with temp correction...This seems very slow. I know that mead takes a while but damn, thats it after 9 days. I never added yeast nutrient. If I added it now, Is there a way to add it now, will it help get it going a bit
