I agree with this.

Other than the cost of the liquid, the price you pay is also includes the cost of the packaging, bottle, cork, label, and case. If you’re buying a wine with an unusually shaped or heavy bottle, you are likely paying more for it.

Sometimes, I wish I was born in a wine producing country because I woud have so many wineries to visit. In Kenya sometimes we get wine at triple the price which is ridiculous.
