Example Input: This is pretty good regular style soy sauce.  But it is not super-wonderful-better than any other good quality soy sauce you can buy in an Asian market.  The main value is as a unique gift.   In the Japanese soy sauce world, there are 4 types: regular, mild (usukuchi), for raw fish (sashimi) and light colored.  Bluegrass soy sauce is regular style.  Compared to Kikoman (a good commercial brand that is widely available) Bluegrass starts saltier, is flat in the middle, then ends with a complex & interesting flavor.  Kikoman is less salty initially and has a round, full flavor in the middle.  Doesn't have the complex ending flavors.  For me, the initial saltiness of Bluegrass is a minus and Kikoman's full middle flavor is a plus.  I prefere Kikoman, especially for dipping sushi where the flavor is more direct.  But I lived in Japan for many years and am used to the standard Japanese flavor.  I haven't tried Bluegrass blended in other food as a background flavor, which is how soy sauce is usually used.   Bluegrass is a perfectly good soy sauce.  Each brand has a different flavor and everyone has their favorite.  If you want a unique Kentucky gift for an Asian friend, this is different than the standard bottle of Bourbon or box of chocolate.

Example Input: I didn't eat any but my baby liked it. She said it was savory but sweet and it reminded her of fine dining in Tuscany. Also I like that with the jarred foods is you know when you recycle it will never become waste. I just learned this and am telling everyone - only glass recycles forever. And if you don't recycle then you and I have nothing in common and you should stop reading here. It's not even a hard thing to do anymore. Nobody else in my building recycles and it drives me crazy. You just rinse it and put it in a different bin and still put it out on trash day. Stop being lazy.
