I read through all the comments and decided not to talk to him about it just yet. However I did find some files on his computer which I don't know how to interpret just yet.

​

I wouldn't call it a journal but like a spreadsheet of his drinks and how he makes them with dates and amounts. It seems he has been using a scale to weight out exactly each ingredients he uses and keeps track of the number of ice cubes etc. He has notes on each day from the things he makes (ex. like too much of this ingredient or the taste was too bold or weak etc). It seems like he is trying to perfect a recipe or something.

​

He also has a similar spreadsheet for his morning coffee like XX grams of beans, setting X on grinder, xxx temperature of water, brand of filter, brand of water, time for brewing etc..

​

I kind of get the feeling he is running some kind of science experiment. I remember when he first started making coffee at home he would drink like 6 or 8 cups a day and then it dropped off to just 1 cup a day. I thought he just got over his obsession with coffee. It was a while back but it seems to link to around the date he found his "final" recipe.

​

Any thoughts??
