How on earth did you interpret I was suggesting you place that kind of burden on a beginner - are you mental?

No! You, the converter make tea for the convertee so all they need to do is put fabulous tea in their face and benefit from your experience.... Or just go to a good restaurant and have actually great tea. Point being is if you want someone to potentially like tea the burden of proof that tea is awesome is on you to prove.

Some might be swayed by giving them stale preportioned box tea that is formulated not to be awesome - just harder than average to fuck up with a long steep time because it's overroasted... But good luck.

I have converted non-coffee /tea people and it's not like they've never had tea before. Some people legit don't like it but more or have been trained to ambivalence because people have given them a lot of mediocre tea and sold them the idea that the mediocre was good. For those people it takes way more than another banal so/so experience solidifing their notion that tea kind of is just "okay" to actually get them curious.
