• Synonym好ましいこのましいWrittenWritten/formal prose for something desirable or that earns a favorable impression; a general evaluation, not tied to the taste of food.

• Related濃厚のうこうNeutralNeutral word for a heavy, strong taste or color, as in 「濃厚なスープ」; it says only that the flavor is intense, not that it is delicious.
• RelatedナイスCasualColloquial loanword exclamation praising a well-executed play or a good choice; not normally used for the taste of food.
• RelatedリッチNeutralNeutral loanword for a rich, full flavor, as in 「リッチな味わい」, common in advertising; it also means wealthy.
• Related良いよいNeutralNeutral, general word for good; 「味が良い」 can replace the headword, but 「よい」 on its own does not specifically refer to taste.
• Related心地よいここちよいNeutralNeutral word for a comfortable feeling of body or mind, as in 「心地よい風」; it can modify 「心地よい酸味」 but does not directly mean delicious.
• RelatedいいNeutralThe colloquial form of 「良い」; 「いい匂い」 is very common, but to say food tastes good you would normally use 「おいしい」.
• Related芳醇ほうじゅんWrittenWritten/formal prose for a mellow, rich aroma and flavor, especially of wine or coffee, as in 「芳醇な香り」; not a general word for tasty food.
• Related豊潤ほうじゅんWrittenWritten/formal prose with a literary feel, for abundance and lushness, as in 「豊潤な果実」; not an everyday way to say food is tasty.
• AntonymまずいNeutralNeutral antonym of 「美味しい」: bad-tasting or unpalatable; it can also describe a situation turning out badly.

「おいしい」 is the default for tasty food; men also use the rougher 「うまい」 in casual speech. Use 「濃厚」 for rich, strong flavor, 「芳醇」 for mellow wine or coffee, and 「まずい」 when food tastes bad. The rest are broader words for good, rich or pleasant things rather than direct synonyms for delicious.
