I have used a couple of others that cost twice as much and tasted them side by side and I personally can not taste the difference. That being said they are all wonderful. No bitter taste. Not rancid. Just fantastic truffle oil here. This is very good and priced great! I will be ordering again as soon as these bottles are empty and that won’t be long! A little drizzeled over meat or veggies. Wonderful mixed with your favorite Balsamic Vinegar on a salad!
