The "best" is always subjective in nature, so no one can render more than an opinion. That said, from year to year, there will be volatility and in any given year the best wine produced will most certainly change. I have had a lot of good Israeli wines and even more that were bad! Here in the US, Yarden is a consistently good producer and is established as a relaible name, however there are dozens that are much better but lack the distribution and marketing. My personal best experience was a chardonnay from
"Domaine du Castel". I find Domaine du Castel folows traditional French wine making practices and produces great wine!
