Scheckter, the F1 world champion in 1979, produces the beers under the name of his organic farm in Hampshire.
The panel ruled in February that the label of a cartoon farmer could appeal to under-18s.
Scheckter said his company’s legal fees for the case had topped £30,000 and that changing the labels would cost thousands more and erode the beers’ brand identity.
He added: “I have had to waste a huge amount of time and money on this whole mess and I am angry that a body with no legislative power can just come along and make arbitrary decisions that we, a small producer, are then left with the consequences of.
“If the multiples stop selling our beer as a consequence, I respect and accept their position.”
Portman chief executive Henry Ashworth said at the time of the ruling in February: “While a child’s drawing may be acceptable for marketing organic apple juice it is entirely inappropriate for alcoholic drinks’ labels. There are no exceptions to the rule that alco- hol packaging must not appeal to children.”
