An up to date article about bittering by Denny and Drew. Some interesting stuff, like...

https://byo.com/article/a-bitter-challenge-simple-thoughts-about-hopping/?mc_cid=a4347f87c5&mc_eid=187f23ae25

"Higher alpha, lower cohumulone hops were once thought to make for a smoother quality of bitterness, but more recent research has shown that cohumulone is simply more efficiently utilized than humulone. Because of that efficiency, you get the same amount of bitterness from a smaller amount of high cohumulone hop. This leads to the perception of smoother bitterness in high cohumulone hops. In other words, by using fewer pellets you reduce the other bittering compounds as well as the amount of astringency contributed by the hops."

The article also describes a test you can do to test a split batch, half bittered with Magnum, half with Chinook.

 Interesting test, which other hops are high in cohumulone though ?

 The Pastry Stouts sound good too.

And this table gives cohumulone percentages for individual hops.
