Great question. I see my role as to share the joy of wine with those around me, so I pour whatever I think is a great match in the hopes of them having an eye-opening experience.
There’s a role for Barefoot and its ilk in the wine world. What I might say to that person is that they ought to try and find a way to taste the two side-by-side as I promise them they will be able to tell the difference. The truth is that the most useful wine drinking skill that we develop is not about ‘tasting’ or ‘analysing’ since anyone can enjoy great wine, … the real skill is developing an ability to remember experiences and compare them over time (“this is better than another wine I tasted a few weeks / months ago” is not something you’d hear from anyone other than a wine geek with a developed tasting skill).
A commitment to learning about, buying and sharing quality wine is a vocation - you have to want to make it a priority in your life because, to be fair, there are many other things that could be important to different people, and I can’t say my way is better.
For example, I might be happy to share bottles at a dinner party that cost £20 each, but I will never understand why someone else would spend a large percentage of their disposable income in order to drive a fancy new car (instead of my 10 year old Seat Altea XL), and I am quite sure the opposite is true.
