Learn Dutch: Hij vindt het aroma van de wijn erg subtiel. - He finds the aroma of the wine very subtle.

In Dutch, when expressing a personal opinion or judgment based on direct experience, like tasting wine, you must use vinden. Denken is used for cognitive thoughts, logical deductions, or things you aren't certain about.

The current lesson is about short-to-long vowel shifts in diminutives (like glas to glaasje). Does a word like aroma follow this rule?

No, because the vowels in aroma are already long. However, it does have a spelling quirk: because it ends in a single open vowel, you have to double the final a when adding the diminutive suffix to keep the sound long, making it aromaatje. The vowel shift rule only applies to a small group of irregular native words with short vowels, like vat (vaatje) or schip (scheepje).

Why is it het aroma rather than de aroma?

Many abstract or scientific words borrowed from Greek and Latin that end in -a, -o, or -um are neuter in Dutch, which means they take the article het. Other common examples you might know are het thema and het risico.

Can I use heel instead of erg in this sentence?
