Hi, I work in a small hotel in Scotland. I have a question regarding the draft beer. Recently there has been complaints about off tastes with our beer and cider, people have mentioned a bitter chemical aftertaste.
I personally clean the beer lines once a week, and have done in the year and a half that I’ve worked there, and these complaints have only started in the last couple of weeks. We recently changed beer line cleaner and I don’t know if it’s a coincidence but there’s been a lot of complaints since then.
Can anyone help me out? Why does the beer and cider taste funny? Could it be because of the line cleaner or do you have any other suggestions?
Any help would be much appreciated as I’m getting a bit of grief and I don’t know how to fix it.
