A bunch of things but usually I know what I need to add (i.e. I'm low on sparkling or light reds) then I usually go for regions, then grapes, both based on my preferences.
@Camille Blake Yes just keep tasting. But also look for the flavors in the real world. Minerality/flint is tough but I would go outside when it rains and look for something rocky (driveway, pavers in your lawn, etc.) and smell it. Same with turned soil, nutmeg. If you really want to get nerdy do a side by side. Get a classic Napa Cab and smell nutmeg before you go to the glass.
Let's get down to some serious business.... who here has actyally had a gooseberry?! I had them but not until I got tired of lying about Sauvignon Blanc. What else yall be lying about? This is a safe space.
I have had a gooseberry but same as you only because people kept talking about it for SB. I put in pavers in my yard and (not kidding) smelled them after the rain once to get the stone/minerality thing. But I have no idea what an orange blossom smells like lol. I will throw that into notes where I think it makes sense but total guess. Same with tomato leaf. Not even 100% sure what that is if we're being honest.
