Hi guys, my last 5gallon brew is aimed at around 4.5% with an Original Gravity reading of 1.041 with a target OG of 1.008. Brewday was 10 days ago. Hydrometer reading after 5 days was 1.030, 7 days at 1.020 After 10 days I'm still on 1.020. Yeast is Mangrove jacks M44 West Coast and it's been in my cellar at a good consistent 19C. What to do? And why is it stuck? Any help will be much appreciated.
