Haven't opened one yet but it has long been a favorite of mine when I lived just up the road (from the winery) a bit for most of my life. I just love red sparkling Shiraz (and Cabernet when it is available) as long as it is made like a quality red and not too sweet.
Big & Bold
This is a knockout red from a winery now US owned (luckily there are still many left in the McLaren Vale area that are small, Aussie-owned, and will be forever - GREAT place to visit with simply stunning wineries to visit and eat at)at a price that reflects quality for the dollar. Great depth, excellent fruit with no aftertaste of sweaty horse collar, dirt and manure (being a bit sarcastic there!) and very easy to slip down with duck, lamb, good beef, strong cheeses or just under the pergola ruminating with nature - something we do a lot of here in the Central Coast of California and back home in Adelaide, Australia when I visit each year.
Light & Fruity
This is an old favourite from when I lived in Australia! A really good value quaffer ideally suited to sunny afternoons around the barbeque with friends and/or family. It slips down easily (too easily on many occassions!), has lots of fruit and a mouthful of flavour. Recommend it to anyone looking for good value red!
