OK, from what I've heard, Centennial is in short supply this year. Several sites are already out, and a few that have some on hand have prices at almost twice what the normal price is. I was thinking that since this beer makes for a great "house session" beer for the warmer months (in LA, that means March thru November) I'd like to buy some hops in larger amounts to have on hand. I was looking at a possible substitute for the Centennial, and I am kinda eyeing Amarillo. Any experiences with this one? Any opinions on it?
