This is my first post and would appreciate any feedback, thoughts and experiences that other brewers have had. Thanks!
Anyway, Ive brewed about five all grain batches and am still pretty inexperienced. I've been using Safale dry yeast (mainly US 05) and haven't had any problembs to this point. However, the last two times I've brewed the yeast has gone straight to the bottom of the carboy immediately following the pitch. Fermentation has started within 24 hours and had a normal 7 to 10 day fermentation cycle with a healthy krausen but the beer smells extremely yeasty and just plain bad after the primary fermentation. There's also been some very small ball looking yeast (my guess is yeast that didn't rehydrate for some reason) still floating on the top after final gravity was reached. I transfered the first batch and dry hopped it for a couple of weeks. It did a good job of covering up the smell and it tastes pretty good. However, there's still a hint of the smell. The second batch is still in the primary fermentor but the bottle I pulled just after the pitch to do gravity readings smells the same as the last batch. I'm planning on giving it the dry hop treatment too so we'll see how it turns out.
Lastly, the yeast had been rehydrated both times and the expiration date isn't until early 2013.
Again, thanks for any help you may have to offer!
