Private labels in the wine industry are a huge—and growing—part of the wine industry. Related questions have been on the Paper 4 exam the past two years in a row, reflecting this trend.
I put an outline together for the advantages/disadvantages question earlier this year! (Still a bit terrified)
Here are a few ideas. With examples bolded. The data is current for 2019.
The growth of private label wines in multiple markets is a result of the advantages that the segment offers to wineries, distributors, and retailers. According to WX Brands, the private label market in the United States has doubled since 2012. In the UK, the market share has climbed to over 45%.
Advantages for the winery
Wineries can either own a private label, or produce a private label for a distributor or retailer. Both options provide advantages.
Advantages for distributor
Advantages for retailer
Disadvantages for winery
Disadvantages for distributor
Disadvantages to retailer
For this essay I concluded that the growth of the category indicates that wineries, distributors, and retailers often view that the advantages outweigh the disadvantages.
Re-reading this shows me that I don't have examples outside of the USA.
Does anyone have any input for outside of the USA?
I'd peruse Jamie Goode's blog. He will occasionally reference or review Wine Society labels (pretty sure this is a UK retailer, but not 100%).
