Well it does appear so. I asked the crews and they tried to convince me the Duval-Leroy was better (it really isn't).
I know this is what I am now referring to as 'business class problems ', but the wine list has really been quite downgraded. I tried a small amount of each of the wines on recent flights and all were ok but none I immediately wanted a refill. Price levels are now similar to that we would purchase at home. QR wine list used to be more 'special occasion' level. (I feel an awful snob saying this, compared with other airlines where the choice is 'white or red?' - but I had become rather spoilt to try some lovely wines onboard that were a little out of my price range)
