Ken Leonards Memory Lapse recipe

Hi there guys , ive been out of pocket for a while now and its good to be back. I just brewed Kens Memory Lapse recipe on the 28 of Jan. and was forced to use US-05 . How big of an impact will this have in taste also i use some grain that i had stored in vaccum seal bads that was never cracked. Its was about 5 months old. Like i said i been out of pocket and was itching to brew a batch. What yall think?

Which yeast did they suggest you use?

I am a big fan of US-05, I find it finishes really clean.

I am sure you will be fine with the grain.
