This is not a Fresh & Easy "exclusive" wine. The ~$20 price tag may have alerted you to this fact. It is, however, a wine that you can get at Fresh & Easy that is an absolutely delicious wine. Elsewhere you can get for about the same price.
If you have a special someone - or if you are a special someone!- who loves Riesling, I'd recommend this indulgence. Chateau Ste. Michelle's "regular" Riesling, also available on F&E's wine shelves, is a good Riesling. The Eroica is a much better one. Collaborating with a German on Riesling (Dr. Loosen, no less) will have that effect.
Since it's not exclusive to Fresh & Easy, I'm not going to give it a value score. Suffice it to say that if you like Riesling and are in the mood to spend ~$20, I don't think you'll be disappointed.
And if you want to make a night of it, I recommend putting on some Anita O'Day.
