It’s time to up your game and shop like a pro. So here they are – a few tips to help you pick out the best of the best and, bottle by bottle, transform yourself into the oenophile your parents always suspected you’d become.Tip #1 Old to NewThis first tip has very little application outside the wine world. In fact, I discourage it for most other life scenarios, especially when shopping for milk or meat. Find the oldest one on the shelf! I always sort the 90 under $20 wine list by “Vintage: Old to New.” These lonely bottles are forgotten once newer, shinier bottles make their way onto the site. That’s a shame because these wines are exactly what makes wine unique, they improve with age! A little mellower, a little more complex, a little more integrated – a lot more interesting.Tip #2 What the heck is that!?Txakolina? Try it, you’ll like it. Lesser known varietals like Torrontes, Graciano, Godello, Txakolina, Falanghina and Mencia, may not be as popular as Chardonnay but, ounce for ounce, these wines are some of this category’s top performers. Complex, affordable and, best of all, unlike anything you’ve tried before. They are a great way to expand your palate and the breadth of descriptors you use to describe wine. Do you want to see why people describe Torrontes as smelling like Juicy Fruit gum or experience what a truly high acid wine feels like? Then try a bottle of Torrontes and Txakolina. Best of all these wines will blow your world of wine pairings wide open. So experiment. After trying some of these you’ll be loath to plunk down twice as much money for a more popular varietal.Tip #3 Swoop in for SavingsSort by savings! You can sort our 90 under $20 list by savings and order a few killer $30-$40 wines for under 20 bucks. Not only will these wines give you the most for your money, but they typically also offer the most in terms of cellaring potential. The higher price can be an indicator that, unlike a $10 bottle, it’s a keeper and the winemaker put an extra level of care into ensuring it will develop over the years. That $30 bottle of Pinot Noir with 93 points from PinotReport is good now, but will also be good in another 5 years and you got it for just $19.99!I’ve shared some of my top picks and my best tips on finding wines, now I’m curious to know about your favorite 90 under $20 wines.
