I’m not much of a drinker of alcohol, but I do think that the storage of spirits can have an effect on price and taste. While white oak is typically the standard, there are more specialty woods that can be used, not to mention reusing old wine barrels. And it hasn’t seemed like there are a whole lot of coopers around these days, and it seems like that it’s still done by hand for a good deal.
Now sodas and juice is now generally just in cheap easy to make plastic, which is also less weight to transport than alcohols that are via glass containers. And since sodas are just from a syrup or mixture made nearer the bottled even less costs.
Plus sodas are targeted for mass appeal. The number of people who don’t regularly consume some soda is probably smaller than the number who consume pricy alcohol regularly.
The podcast Gastropod, has had episodes about barrels, soda and glass bottles, and also about the rise and fall of bottled water. Among many other food science topics.
