I have an almost one year old Teamaker rhizome that I bought for the purpose of experimenting with sours but I have read that when using unaged hops in beers the beta acids become bitter as they age. A ratio of 2:1 alpha to beta yields a beer that keeps roughly the same bitterness level as it ages. So the 15% beta acids in the Teamakers might be extremely bitter after a couple years.
