All good perspectives. I really just wanted to point out that I was a regular VM buyer since the day they started but find it hard to pull the trigger these days and buy (its been months). I'm still a fan of VM and I think part of the reason is I tend to pass on dozen lots as I want to have variety in my cellar and not too many volume wise. I very rarely sent any back but over the past year I have sent a lot back which may be because VM are giving less clues these days. I wonder if as VM grow they are under more pressure from suppliers to take the whole shed full and they can't be as selective as in earlier days.
Sorry, I'm getting confused as to what your actual beef is with them? First you seem to be implying they only offer a few wines (aka you can tune in three times a year). You also seem to be saying now that you don't like dozen lots, and want more variety packs due to limited space. And you're also sending things back because you don't like them - is that because they're low quality wines? I really understand the problem.
FWIW, based on what I can recall, these threads and my purchases, just this year they've offered:
Seppelt (Jaluka, Mt Ida, Chalambar)
Wynns (Black Shiraz, Cab Sauv, V&A Lane Cab Shiraz, V&A Lane Shiraz)
Lindemans (St George, Pyrus, Limestone Ridge)
Rosemount (Balmoral, GSM)
Wolf Blass (Grey Label Shiraz, Cab Shiraz)
Devil's Lair Cab Sauv
Parous Shiraz
Shermeldine Merindoc
Top of the Tree
Adelaide Winemakers Quorum
Hungerford Hill
Forest Hill Block 9
Hardy's Thomas Hardy Cab Sauv
de Bortoli (Pinot, Bianco)
Stefani Chardonnary
Hermera
Two Hands (various)
Lou Miranda
Capel Vale
Amelia Park
3 Oceans
Phi Lusatia (Chardy and Pinot)
at least half a dozen more Reislings and Chardonnays, one desert wine, a half dozen imports, Hand Crafted by Hardy, Duck Sauce, Art of War, Krug, Yalumba Scribbler, various Prosecos and sparklings I haven't bothered to check, the Orgy, Old Money and so on. Pretty much all available in 6 packs, some are 2010. There's even a 2005 vintage sparkling there right now.
There's enough there to do at least one new (and think probably two new) per week - if that would make you happier. And if you want aged wine at a decent price, I think you need to go to Dan Murphys - cellars are not really in that business - you can see the paucity of stuff by signing up with Langtons - it gets snapped up very quickly and doesn't sell at a discount. I've managed to get aged Clarendon Hills and Killakanoon in the past few months, but you're pretty much paying full price - not VM's model.
