Amber ale. Need input.

Need thoughts on this one. I have not done anything close to this style yet. I want a complex flavor profile with not too much alcohol.

Amber malt is pretty intense- I only use 6 ounces of it with 13 pounds of 2 row in my IPA. It's got a very strong flavor, in my opinion. If you have experience with it, though, and like it, I would defer to you on that since I rarely use it.

I'm not sure about the hopping- all of those different ones might just give you a "muddy" flavor. I'd pick two complimentary ones for the aroma/flavor. (I'd not use the willamette, in other words)

If you do end up lowering the amber (listen to Yooper, she knows what she's talking about), you can get a little color back by adding 2oz. of crystal 120L. It will also give it a bit of complexity.

Here's what I found when I was looking to brew my 1st amber:

The amount of amber was my main concern and I think I will lower that.
What is the muddy hop flavor you mention and why no willamette?
Thanks!

For my Ambers I like to be in the 17 SRM range I like the deep red color. I always like to add some C120 to my ambers.

Muddy hops flavor comes from too many varieties competing for dominance of flavor. Use a distinctively American variety for flavor and aroma, and a neutral bittering variety. One of the citrusy "C" varieties will work well in a flavor/aroma capacity, as will Amarillo.

Magnum is perfect for bittering. Just don't go too crazy on the IBUs.

+1 to the idea of a little dark crystal. 4 ounces should be perfect. As I wrote in the Wiki article, Amber needs a broad spectrum of Crystal-malt flavors.

That's also quite a lot of Aromatic and Biscuit, too much for this beer. I have trouble telling them apart, anyhow. Me, I'd keep the Biscuit and swap the Aromatic for an equal amount of Pale Malt.

Cheers,

Bob
