Both kegs have long since kicked. But, from my notes:
The real centennials stayed truer to what the bag of pellets smelled like.
Fresh, bright, and citrusy. The keg stayed really fresh longer than the types.
About 3 weeks into the "type" keg you could taste some dank hop taste. It lost a lot of it's flavor compared to the real deal at about a month and you would get a firm bitterness with a hint of what they smelled like going into the kettle.
If centennials were out again I wouldn't hesitate to pick these up as a sub. They
don't make the same beer but a close approximation. But, you guys probably already knew this.
