FYI: blind taste test
« on: March 17, 2010, 04:29:48 PM »
I had my wife serve me four glasses of Miller, two from a bottle and two from a can, all prepared in the kitchen while I waited in the living room.  I can tell the difference 100% of the time.  The bottled beer is clean while the canned beer has a dull cloyingly sweet and bitter flavor.  Just in case anybody wanted to know if I would actually do the test.   ;)

How many times have you repeated this?  Is it can/bottle or lot/lot variability?

I purposely bought two 24 ounce bombers, one bottle and one can so that it couldn't be one can or bottle different from the rest.  I've always been able to tell the difference, but I've never tried it without seeing which one went into the glass.  Usually if I'm drinking BMC beer I don't even bother with the glass though.  Interestingly enough, I did like the extra bitter from the can, but then I'm kinda hooked on bitter beer too.  The cloying sweetness really stood out in the comparison though too.

I'm sure someone will say I should have done more but if I were to do ten glasses then why not do twenty and see if I notice if someone slips in a Bud...    :D

The real accomplishment is that you got your wife to pour you 4 beers.

Thanks for bringing this up. I'll have to try this myself a some point.

Thanks for doing the test and reporting the results, Dean.  2 questions remain now...first, what is it that's causing the difference?  Is it the cans or something else?  If it is the can causing the difference, what about the can is doing it?  Second, why is it that no one else has reported this?  Is it because no one has done the test the way you did it, or is it something else?  I'm teaching a BJCP class and I think we'll do this for the class.  That way, we'll have 15 more opinions from some people who are pretty good tasters.

I've noticed the difference between cans and bottled counterparts. Anecdotal evidence is often influenced by subjectivity. So why not try this with a group of 15 as Denny is suggesting and get the real skinny.

Though, for Miller products, is region important and an influencing factor?

I agree it is good information to build upon.  I have to admit what you describe in the difference is not what I expected.  I expected a report of something tasting metalic, which is not the case.  It is interesting to hear the description being cloying because that is something I guess normally would be attributed to a bad fermentation or overuse of an ingredient.  I'm also interested in what property of can a can makes it bitter. 

Denny, if you are going to go ahead and do a larger sample I'd make one suggestion.  Do it with both BMC beer and a craft beer.  I'd be really interested if a noticeable difference is in cheap crap beer, just craft beer, both, or neither.

I will if I can find a craft beer that comes in both cans and bottles.  But if it's due to the packaging, it seems like it shouldn't make a difference whether it's mass market or craft beer.  Next class won't be til 4/12, so it won't happen til then.

I think BMC is actually better for this test - less native flavor to mask the flavors you aim to detect.

I am anxious to hear further results.

Thats why I chose Miller High Life, its clean and has a low flavor profile, no specialty grains or at least a very low amount to throw your tastebuds off.  Let us know how the test turns out Denny.

I must admit I'm quite surprised.  Although you didn't repeat this enough times to eliminate chance, it's at least somewhat unlikely that you would guess correctly twice in a row.  Did you find yourself mulling over your choice or was it like instantly 'that's it!'.  What about the freshness dates on the bottles cans, were they comparable?  I'll have to try this myself next time I head to the store.

I'm a bit confused by your taste results, the can was both sweet and bitter?  For me when I taste a beer that is sweet it is lacking in bitterness.  Bitterness could be from metal exposure, but sweetness has to be a fermentation or recipe issue.  You may have had a lot-lot variance which affected the outcome.

If you do the test again, a better one would be a triangle test, where you have two beers from one side and one beer from the other, and you pick out the beer that is different.  When doing a single side-by-side, you know they are different and you can sometimes get a false positive this way.

Nyakavt, since I hadn't had any Miller in at least 4 months and didn't taste either one before the test, I could not directly or immediately say which one was from a bottle or a can... what I was able to do was put them in order as to which ones tasted the exact same... ie the two glasses that were from cans were together and the two glasses that were from bottles were together.  Try it and you'll see what I mean.  Thats what kind of surprised me, I liked the extra bitterness of the can.  The bottles are cleaner... softer might be a better word for it?

Where does the extra bitter come from.... I believe it is from contact with the aluminum.  What is the chemical name for baking soda... I can't think of it, but it reacts with aluminum as I described in the cookware test... but the concentration is higher in the cookware test and it tastes like crap.  Anyway this is just a guess but I'd say all beer has some trace amount of that chemical in it... some beer has more?

I'll dig out the bottle and can to check the date on them...

 Second, why is it that no one else has reported this?  Is it because no one has done the test the way you did it, or is it something else?

My guess would be because it's BMC. It's pretty much gonna suck either way!  ;D
