I was recently at a beer festival and one of the breweries (Fulton) had a delicious pale ale that had been infused with grapefruit. I asked the brewer how they did it and he told me that the night before when they kegged it, they quartered a bunch of grapefruits, scored the peels, and threw them in the a bag in the keg.
I have 10 gallons of pale ale that I need to keg soon, and was thinking about doing this in one of the kegs but I don't want to destroy 5 gallons of perfectly decent beer. This is where I need your help.
- Is this safe to do if the whole keg isn't going to be drank the next day?
- Are there any sanitization precautions I should take before just throwing a bunch of grapefruit into my keg?
- How many grapefruit do you think would do the trick without being overpowering?
- Is this just a plain bad idea?
