Just a word in defence of the JO site, I find it a very useful resource and use it almost every day.
If I want winery reviews I go to the JH book, but often new wineries aren't there either, 2,000 and growing is too hard to keep up with. The wine forums are a better source of info for emerging small makers like Warrabilla, Kalleske, Glaymond etc.
I use the JO site for reviews/ratings of new releases I haven't tried and to check cellaring/drinking windows for new and older wines in my cellar or about which I've been asked. It's very useful to me in deciding whether to list or not list a wine on my own site if I haven't tried it myself.
Yes, the articles are pretty brief and sometimes superficial, but some of them have had useful information for me.
Yes, the site is a bit clunky, with lots of images that slow the display on some pages, there are many recent vintage wines where there are only ratings and not TN, there are gaps in the winery coverage, especially the emerging stars, but that's not a problem, we find out about them here anyway.
Since I'm close to a computer most of the time, I don't buy the book anymore, just subscribe to the site, so it only costs me about $14 more than buying the book. For me that's money well spent, especially as I find my palate often agrees with his and his drinking/cellaring windows are usually pretty close to the mark if I shorten the end year a little.
So, horses for courses, it depends on what you want.
If you have only just joined and don't see any value for yourself, it would be worth asking for a refund, you never know JO may appreciate the feedback. This is the only email address listed on site:
enq@onwine.com.au, send me an email or PM if you want JO's direct email address.
