Anytime ! Some brewers use more rye (in some beers), but you like this beer, and using a higher amount of rye can lead to a stuck runoff. I say go with what tastes good to you. This'll be good.
Yeah I thought it was a low % as I couldn't make out a lot of rye taste in this beer. Although I have little to no experience drinking rye beers.
IMO, 15% rye is about as low as you can go and still detect the rye. I've gone as high as 40%.
