Absolutely! We encourage you to rate every product you taste, every time you taste it. Our algorithms use every rating that you submit to build your personal preference profile.
People's preferences change over time, and you might not react the same way to the same product every time you taste it. Perhaps your preferences are changing or perhaps you had a bad bottle. Or circumstances may be different – as weather, occasion, and food all influence what you taste.
Rating multiple vintages of the same product is also useful. Within your Journal, you will find your ratings organized by product, with various ratings of the same or different vintages aggregated.
The ratings badge at the top of the card will be your most recent rating of that product.
