Hello Jangles sorry for the late reply but I haven't logged in for a while. And nah I didn't dump the whole batch just the 3 litres of DME yeast starter and the yeast that was not activating quick enough. Iv had a few starters not ferment due to long storage.
If you have done a starter from a liquid yeast. How long should it take to start. As I normally see strong fermentation within a few hours. But I recently started an abbey ale and it took two days to show signs of fermentation.
