They are after the Melanoidans.


Love the Mac -n- Jack's. It's good to be here near Seattle.

[BigNastyBrew]

Cool! Thank you.

How necessary do you feel this is?

Cool! Thank you.

How necessary do you feel this is?

I would say it's probably not super-crucial, but you could just add a couple ounces of melanoiden malt if you were feeling super lazy. But I'd just go with the 90 minute boil.
Mac & Jack's makes some killer beer. Their IPA is pretty great too, but I haven't had it in a looong time.
Cheers

Thanks. I'll just go 90 minutes.

I've never tasted the beer but I've heard so many good things about the Amber..and I like ambers.

I made this recipe in March for a party. It's a nice recipe.

I live a few blocks from Mac & Jacks, and still haven't been by to see the place. too bad they don't have a pub or tasting room. I feel like it's a crime that I haven't had any of their beers besides the Amber

[BDawg]

Mac & Jack's have a pub in the Seatac Airport, with all of their beers on tap.
