I tend to agree on the under £10 point. Well, not that you can’t find a decent bottle of wine under £10 but just it is rare to find a wine under £10 that really blows you away.
I understand that they do taste in price brackets, and it took me a few years to work this out. So they will have a session of £5-10 wines, £10-£13, £13-15 etc. I am not sure they are the exact brackets but it is a similar system. They don’t overly publicise this so I think there may be some valid confusion that someone thinks that as they are all declared champions, and tasted blind, the £7 bottle will be as good as the £15 bottle.
So, you’d have to assume that when they declare a £8 wine a Wine Champion that it is very much a ‘Wine Champion’ if you tend to spend £8 on a bottle of wine but probably very much not a wine champion if you tend to spend £15 on a bottle of wine. Obviously, this may not always be the absolute case but they do not taste price blind. So just because you see two white champions, one at £8 and one at £15 does not necessarily mean they are actually comparable in quality, just that they should be better than other similar types of wine at similar prices.
To make it slightly more confusing, there is a secondary announcement of fine wine champions later in year starting at roughly the £15 bracket. Personally, I’d rather they did the whole lot in one go or at least raise the price point for the ordinary competition to £20. It would also be nice if the wines declared Champions were identified in the bracket they were tasted (new world white under £10 as an example).
