Hi all,

Im doing research on diacetyl whereby I am going to build a model in matlab
to predict whether the fermentation is bad based on the first 48-60 hours
using past datasets .  I was wondering if anyone could send me information
regarding diacetyl or past work done on this subject.  What is diacetyl
affected by during the course of fermentation... ie. I have data on yeast
generation number, time, temperature, specific gravity and VDK (diacetyl)
for 43 bach fermentations.  Can anyone tell what links are between Specific
gravity and Diacetyl concentration.

I need to plot a graph of  'Time taken for diacetyl to be in spec. (i.e
below value of 0.1)' vs. 'steepest slope of SG curve'). Any idea on what I
should expect?



Can anyone help?

John tery posting this on www.brewandviews.com.  There is at least one
poster there, by the name of Fredrik, who has done some work on
something similar.
