California big reds laced with Mega purple are in vogue.
You do realize how few and far between people are with the knowledge of Mega Purple. And yes, virtually every Californian wine under $20 contains some amount of it.
Wines are very subjective. For example, if you have one person who likes old world French Bordeaux, another who like big Mega Purple Californians and another who likes Manischewitz, you're not going to please them all with one bottle/style of wine. That said, you're buying so the number one rule applies. Buy something you like.
Go to an LCBO that has a tasting counter and sample several different ones before you buy. You can also ask a product consultant to help you. Be aware that some are more knowledgeable than others and not all get to taste wines from each release. It helps if you at least have a style of wine you're looking for and a budget per bottle in mind before you go.
I have a my go-to LCBO product consultant. I go to see him each release. He'll usually pick 4-6 wines for my wife and I to try as he knows what we like. If we really like them, we'll pick up between anywhere from a couple to a case of each. I write the month and year purchased and the price on the back and stick them in our cellar. We currently have 350-400 bottles at the moment. Purchasing multiples allows up to see how a particular wine ages year over year.
Occasionally we'll have a party and do a vertical tasting. One wine varietal from the same producer from several vintages. At our last party we sampled 2005 to 2009 Caymus Cabernet Sauvignon. Delicious!
This is my pick for a surprisingly well rounded, non-offensive budget red. Luccarelli Negroamaro LCBO#: 380972 - It's only $8.95 a bottle.
