hello, I am a first-time brewer, I followed the recipe quiet to the point, my brew is now 7 days old I divided my wort into 2 portions to add different flavors. I batch I put in a fermentation bucket ( about 2/3 full ) and one I filled a Corboy ( about 1/4 full only ) put an airlock on both. on the brew day, as per the recipe and I added the yeast as instructed, 2 days later I saw very little activity, in the bucket and nothing in the Corboy, post that I found out that the yeast that I added initially was dead, so once again I added yeast to both the bucket and the Corboy, it has been 3 days now and still I see absolutely no activity in both. I am worried have I spoiled my entire batch or is a solution to revive this. please help !!!
