A few years ago, Sun King made a great Belgian Golden with what they said was a "mixture of 7 yeast strains". If I ever get a chance, I'd really like to ask the SK guys how they did this...
Can you match up the Belgian strains with similar behaviors/attenuation ranges this way? Kind of like Hopfen described with the PU strains.
If you dump enough yeast in, will it give you something different (and worth the price of all that yeast)?
