I rehydrated 2 packets of US-05 using this method: http://mikesbrewreview.com/how-to-rehydrate-yeast/
I dumped the dry yeast into sanitized pre-boiled water at 95 degrees and let it sit for 15 minutes. Then I stirred it with a sanitized fork to break up the clumps and let it sit for another 15 minutes.
When I went to dump the mixture into the carboy, it went in smoothly however there was some residual dried yeast stuck to the bottom of my pyrex cup which I was unable to use.
Is this normal? Should I have stirred it again right before pitching?
On a positive note, it started showing signs of fermentation within a few hours and the air lock is bubbling.
