In a foreign store with unrecognized coffee packaging;
You see the coffee right here in front of you at eye level, you just don't recognize the product as being coffee.
It might not sound the best, but isn't it technically correct given its the present tense.
The coffee is the direct object of the sentence, hence in accusative case.
der goes to den after any verb except sein (ich, bin, er, sie, es, wir, ihr)
Why not, "you watch the coffee"? Makes more sense to me, in the sense that you would watch it brew and make sure it does not burn, etc.
