comparing German wines to US wines

[Jason]

Randy,
This has caused me to do a bit of digging. I had remembered from MS program about the BA equivelance but I also did check with Robinson before I wrote. After more digging, it seems our fellow BB member, Tom Stevenson has the best info. His explanation answers our questions very well.
Apparenlty Eiswein did in fact become the sixth predicate level in 1982. This would make sense as previously it was annexed to other predicates, (as you noted) and your book from '83 was probably printed to late to catch the update.
Tom also states that the Oechsle level can be as high as TBA but is still very different because of the lack of botrytis. I was not aware that Eisweins are noteable for their high acidity. Thank you to Randy and Tom on this one.
