I was reviewing the first post of Hop Hunter on this question : "FV" abbreviation in BrewDog recipe
I find it doesn't answer the question, but I hesitate to flag it.
Answers that are not based on any facts, just on "I think it is this" usually don't bother me because an opinion can be welcome sometimes. However, in this case, the answer has already been posted, so this one doesn't add anything more.
What do you think?
