Wow - this thread is a ticking time bomb - I do not manage this board, but as a member - I think I can ask for etiquette. So, how about laying out the facts - though this is my slant on the subject:
1) Kosher or not every bottle has its day and then its blooms fall off (some faster than others). So, if Daniel gives a window and a score at the last tasting, I would take that to mean that the wine will be best appreciated in that range of dates - and will probably not get much better, and can only get worse - over time.
2) Now people weigh many things when they buy a bottle of wine (again kosher or not), value, previous experiences, cost (for the snooty of us), prestige, label

,etc.
3) We may like a wine that Daniel does not, which is perfectly fine, and something he has stated many times before.
However, if a wine is oxidized or way past its prime, saying that Daniel is a critic and therefore cannot appreciate a simple wine - is basically absurd.
So if company X is selling a wine that is over the hill, it is good to know that - so that we can add that to our decision matrix. Now the next set of facts:
1) Most decent wine stores will help you if you call them and tell them
honestly that the wine is bad
2) Wine stores do not taste the wines every week, so they take the reviews they get from their distributors or wineries as the gospel and reuse it as it was when they got the bottle. It would be nice to have a recent wine tasting notes - but that is not always possible
3) Wine stores are in business of selling wine. They understand the laws of supply and demand. They drop the price until demand increases - simple. That means that a Gan Eden wine that has long gone over the hill, can be sold for a buck or two. Nothing wrong with doing that - it is your decision and it is your business to understand why a bottle is being sold for a dollar or two.
4) Wines stores want your business - call them up and ask them what they think about the wine ask them if they think the wine is over the hill. If they are not honest - they are not worth your business.
5) Wines stores that act honestly with you will get your business. I and MANY of my friends buy wine online and many of them are wine newbies. They buy it online because the price, service, and quality is to their liking and when things go wrong they get service that is equal to other business that do well online - electronics, clothes, etc.
I hope this is not too long a rant. Having Daniel and others tell you what they think about a bottle is not bad - it is good for you and for the industry. It is up to you to decide what to do with that data.
Best Wishes!
