Objective: Talk to Sarah Filburn

Sarah Filburn wants me to sabotage her brother-in-law's latest batch of beer so that he's forced to work on IntelliWheat, instead. I have to go to Henry Filburn's brewing operation and figure out how to do that.
Objective: Sabotage the latest batch of Henry's beer

I've tampered with Henry Filburn's latest batch of beer. Now I have to wait for it to finish brewing. It shouldn't take more than a day.
Objective: Wait one day for Henry Filburn's beer to brew

Henry Filburn's latest batch of beer is done brewing. I should go to the Stoneroot Inn and see how the patrons like my "improvements."
Objective: See reaction to Henry Filburn's latest beer

Henry Filburn's new batch of beer has gone over terribly. Just as planned. I should tell Sarah Filburn the good news and get paid.
Objective: Talk to Sarah Filburn

It turns out that upping the alcohol content of the new batch of Henry Filburn's beer made his beer more popular than ever. Sarah wanted to pay me to sabotage the beer, so there's no way I'll get a reward now.

Sarah Filburn's sabotage of Henry Filburn's brewing operation was successful. In time, it should force Henry to focus more on the IntelliWheat side of the business.
