Help identifying beer aroma

[rhys333]

I brewed my first batch of Centennial Blonde recently and and cracked the first bottle yesterday after two week of conditioning. Great beer by the way! I noticed it is distinctly aromatic (sweet floral), and I'm wondering which of the ingredients made that magic happen. For those that aren't familiar with the recipe, it contains the following:
2 row
Crystal 10
Vienna
Carapils
Centennial and cascads hops (note: had to sub Columbus as LHBS did't have Centennial)
Nottingham yeast (I used US 05)

I'm assuming the sweet aroma is from the crystal 10, but not sure about the floral. Eliminating ingredients I've used before, I'm left with the vienna malt and Columbus hops. I used Columbus at 60 and 35 mins, so guessing there wouldn't be a strong aroma from them . Is it the vienna????

Thanks in advance.

Probably all of the hops. Columbus has a spice herbal note to it that you're probably picking up on. Both cascade and centennial have citrus and floral aromas and are a classic pale ale combination. Here's a hops chart that will help you select your hops for particular aromas and flavors.

Thanks for the chart. That'll come in handy. Interesting that it's the hops. I've used cascade quite a bit before and picked up the citrus, but nothing floral like this. Pretty cool that the columbus-cascade combo would do that.
