I've tried this and it's very drinkable. Well worth it for the price. Average rating of 3.4 on vivino.
Make sure you use both coupons to get the price. I think they've left their store one there from their previous promotion.
Note: The store coupon (JWEXTRA10) expires tomorrow, so get in now if you want the extra discount. Thanks for the heads up MiscOzB!
Note 2: I notice that Just Wines updated the listing at some point tonight. Not entirely sure which year they're selling now, but probably doesn't make too much difference. If anyone wants more info on the winery and the specifics of the wine, here are the details.
Thanks OP.
Surprised that we were able to stack two codes to get the combined discount.
