I recommend buying wines from Different Drop.
They are independent and offer a 100% satisfaction guarantee, which is
reason enough in my book. But more than that, they stock wines made by
small, sometimes tiny, independent wineries that make truly outstanding
and individual wines, with a large variety of grapes and blends, and are
not made to a formula. ie. the wines aren't boring factory plonk.
These are the wines I'd like to keep drinking because I enjoy them, and if we don't support the independents we will lose choice.
Of course I recommend buying direct too.
I do pay for the wines I review. Different Drop allows me to access low volume wines on a single bottle basis.
At least until wineries start sending me bottles directly for review.
