OK - Maltese wines are changing - alot of what used to be labelled Maltese wine was actually Italian grapes imported into Malta, processed and bottled here. Under EU law, this can no longer be called Maltese wine, so it means 3things 1. alot of new grape vines, and 2. what was good before isn't necessarily so any more 3. some really good (but expensive) local single variety, small vineyard wines. Another thing, the tax on imported wines was eliminated on joining the EU, so wine prices have come down
price ranges (supermarket prices - restaurant prices normally LM2-6 on top)
under LM1 - alot of dodgy wines, but Red Label has improved alot - Green Label not so good. La Vallette also good - not sure of any local white would recommend at this price, but the Villa Tritone, an Argentinian white (and red) is very good at 90c or so
LM1-2 - very good selection - Marsovin used to be best, but gone down hill, while Delicata really improved - their Merlot (from Italian grapes for now) is excellent, but wait and see when switch to local grapes. For white, chardonnay or sauvignon blanc from Marsovin and Delicata good.
LM2-4 - really like Laurenti chardonnay and the Cheval Franc from Marsovin (?)
LM4-6 - the newish Grand Cavalier range (from Marsovin ?) is very good - worth the price ? Maybe no better than the Laureni and Cheval Franc mentioned above
will try to add more
