Two more 'newbies' questions
1. If I use US-05 yeast, do I need to use 1 pack or 2 packs? (2 vials of California in the recipe, this is why I wonder)
2. When you bottle beer after 3 weeks (1 week on primary, 2 weeks on secondary), do you add sugar/glucose/sth else to the bottle to start re-fermentation?
