Here's a review of three RY4s from Janty, the company that invented the original RY4. These RY4s follow the classic formula, serving up a bright, balanced, and slightly sweet flavor. They're quite different from modern RY4s, which have heavier caramel and vanilla tastes. I thought that DK and Classic were excellent RY4s -- among the best synthetic RY4s you can buy today. DK RY4 is my personal gold standard -- the one that I compare all synthetic RY4s to. Full review and steeping notes here.
