I generally strive to use the same shape of bottle that would traditionally be used for a given grape variety. I.e., I put Cabs and Merlots into Bordeaux-style bottles, and Chards, Viogniers, and Pinots into Burgundy style bottles. I fudge it with Italian varieties. However, I must admit that I do not like (for practical reasons) Burgundy bottles. First of all, they stack poorly in my experience (sometimes trying to make a "leap to their death" from the rack.) Secondly, because I mostly drink Bordeaux varieties, I optimized my wine rack for Bordeaux bottles. Third, I don't have as ready a supply of Burgundy bottles, because I don't drink so much of it! Okay, so I am going to make Syrah this year from grapes. I expect to net north of 60 bottles. I am trying to decide whether or not I will be a purist and insist on using Rhone/Burgundy bottles. (I don't distinguish between those -- I am certainly not that much of a purist!) I am curious what you fellow winemakers do -- be "authentic" or "pragmatic"?
