Attenuation is rather poor due to the Munich malt I used. I used Franco Belges and this is likely the last time I use this malt.

This seems like and odd statement from you. A single usage and you discount this at the issue?

I don't have in my inventory who my base Munich malt is from, but I suspect it may be MFB and if so have never had an issue with it.

Kai, did you do this as a blind tasting?  I look forward to the results of that kind of test.

I did 3 sets of two and was able to get the first one right. On the second one I noticed that the lingering bitterness is not easily erased by the next beer which does make distinction on this characteristic difficult.

I also didn't draw enough beer for large enough samples for more thorough tasting.

Denny . . I know you are pragmatic!  ;) (Maybe I an too . .)  

So, let me ask a question in response to your question . . Is it not possible to make an objective judgement of flavor without doing a blind test?

 

Maybe, but my experience is that as long as you know which beer is which, you will always have a bias on a subconscious level.  For instance, in my FWH experiment, when I poured the 2 different beers for myself, I was sure that I could tell which was which and what the attributes were.  When my wife poured 2 of one and one of the other, it took me 3 tries to pick out the different one, and even then I was wrong about which one it was!
