We have two favourite purchases from Aldi, Shiraz and pinot grigio, which are consistently decent quality for us.I really like screw top bottles for sheer ease of opening, but the corks do come in handy as my garden is nearly all patio, so lots of containers. I don't entirely choose my wine according to method of bottle stopping though!
Though I do like the little frisson of buying something different and having to dig out the bottle opener.... Hoping the cork won't crumble and it will pop out in one go!
