A drink range of Now till 2044 isn’t saying that the wine will be better in future, it’s just suggesting one drinks it before 2044, i.e. I read it that the winebuyer/producer are pretty confident that it won’t be past it in 2044.
We have different tastes and some don’t like aged wine and prefer the freshness of young wines.
As for TWS keeping the wine and releasing when they think it’s at optimum drinking - it’s a quandary as other merchants will be selling it now and why should they lose customers to them.
If I was given* a bottle of this, for certain I wouldn’t wait 15 -20 years. The wine may not be over the hill but I certainly will The times when I bought wines for aging that long are in the past now.
*I won’t be buying, I remember when Majestic at Farringdon had Penfold’s Grange Hermitage at an affordable price and the price now seems silly.
Incidentally, I see a photo of a Grange bottle in the 6 Wonders of the Wine World but when I click on it there are only four wines - and no Grange. But 2009 Grange is available at £340 a bottle
