I think Jalets is a weird ‘product’, some negociant purchases plus leftover vats that don’t make the cut for their estate bottlings. That doesn’t seem like a recipe for consistent quality. The 2016 was ok, but my example was heat afflicted. I have not opened (or found) my 2015 which I hope is better.
PJA seems to have this long running issue with their growers, that, as they gain confidence in their work, they stop selling grapes, and bottle it up on their own. So the branded blends are always losing their best input.
