Oh I just got another idea if you got the time and patience to work through it...
Get yourself a french press coffee maker;
And build up a note card library of each grain....Take maybe a couple ounces of each grain, and steep it in a couple cups of hot water, drink it and then "color" it.
DO this over time, like whenever you pick up grain for a recipe, get a couple ounces more for this experiment. And start to build up a notecard taste/color library for each grain...Do both Base and Specialty Grains
Draw on the card and then note what the grain was, including lovibond and stuff.
Once you get through the base and specialtys grain, maybe then do the same thing with a fixed amount of two row and a fixed amount of hops....you may have to actually ferment these micro batches though. BUT it might work if you just were to steep the hop with the grain tea as well..
I guess you have to include adjuncts as well.
Then you could start doing combinations of grains....
After doing this, would have built up you mental and pictoral repetroir of ingredients.
You SHOULD with practice be able to construct a beer based on your cards, and also perhaps be able to deconstruct beers as well...
Oh also, anytime you taste a commercial beer, don't forget to do a card on it, and label what the beer is, that might help you to be able to deconstruct those later.
WOW, this is weired but it kinda reminds me of what I talk about in my E-Book on what I called "practical mysticism", and the 6 weeks course I used to teach based on it...there's a series of exercises I took the participants through to change the patterns of how they perceive the world...I dunno if reading it would help...at least the exercises I mention in it, they may be helpful.
