Why Is Diet Root Beer Up 131% Even Though Aluminum Is Down?

This may count as an “old man yells at cloud” moment, but before the Flu Manchu lockdowns and the resultant supply chain breakage, HEB’s house brand of Diet Root Beer went for $2.25 a 12-pack. Now, here in early 2025, it’s going for $5.20. I calculate that as a 131% inflation rate over five years, considerably above the official 21.9% phony baloney “let’s lie for Biden” rate. So what gives?

My first thought was “Well, aluminum prices must have gone through the roof again.” Nope.

Aluminum shot way up in 2022, and then came right back down, and has been essentially flat for two years.

As one of the biggest costs in soft drinks 12-packs, you’d think prices might be stable for that, but no. The prices for name brand soft drinks have gone up as well.

Even if we can all agree that the real inflation rate is much higher than admitted, why are soft drinks up so much more than even the unofficial rate?

If you have any idea, please feel free to share in the comments below.

    When Spanish speaking gatecrashers showed up in Texas they were immediately awarded SNAP cards but didn’t have the requisite ID to purchase alcohol. The root beer was purchased as a “Cerveza” substitute.

    This unanticipated demand drove prices higher.

    Admittedly, this is as unlikely an explanation as anyone else can offer…

    Nowadays the name brand sodas are marketed with a high individual price (~$10 / 12 pack), but with weekly offers such as buy 2, get 2 free. So they are pushing quantity and the effective price is about $5 per 12 pack for those who would drink that much.
    As for the store brands, I think they’re just rising because people will pay that much when they only want one 12 pack at a time.

    I believe it is mis-managed production. For example, I live in Iowa and getting the small 12-oz bottles is nearly impossible. I extrapolate that the soda sellers are using more aluminum than plastic. Or possibly their distribution is still screwed up from Covid. Or Walmart is simply cutting back on choice because it costs them money.

    Because they can! Inflation is the excuse

    Because many many retailers and suppliers in the chain have taken advantage of the situation and simply raised prices. If the market can sustain it without them losing business, BAM, they made a great decision. If the price is too high, sales will suffer and price will come down. It pure old supply and demand and some companies are pushing the limits. $6 for a bag of chips?!! Crazy

    Raw materials costs are twice as significant as packaging costs in CSD production. Carbon dioxide is the single greatest cost in CSD production. American carbon dioxide prices are up well over 50% since 2020, as tracked by the BLS’s “Producer Price Index by Commodity: Chemicals and Allied Products: Carbon Dioxide”.

    The U.S. price for bulk carbon dioxide gas was about the same as the global market price in 2020. Today, the U.S. price for bulk carbon dioxide gas is more than double the world price due to:

    1) cartelization in the American industrial gas industry,
    2) massive increases in urea fertilizer production consumption,
    3) tremendous consumption by petroleum EOR, and
    4) massive sales of American LNG to foreign customers.

    LNG prices have relaxed since 2022, but there is a huge shortfall in carbon dioxide production capacity due to cartelization. Linde, Air Liquide, and Air Products control over 70% of the American market. They set the prices.

    Also, the price of carbon dioxide gas rocketed up 30% in the 30 day February – March 2022 period. Care to guess why?

    My brother, an HEB store manager for many years also stated 10x25mm’s observation, and adds the other product ingredients, fuel and labor costs are a lot higher as well.

    Information that doesn’t answer the question, but may raise some:

    A 390ml bottle of Coke is 12,000 VND at the Kwikimart in Saigon. That’s under fifty cents, and it seems to be on a buy two get three sale every three months. I think cans are comparable, but on a different discount rotation – ie month one no deal, month two bottles, month three cans.

    I’m guessing that root beer is an expensive luxury import at the specialty store.

    BMI/FYI, a Big Mac costs 79 kiloDong, a little over three bucks.

  9. Gospace says:

    The likely factor is transportation costs. The soda itself is the smallest part of the cost. Soda is cheap, mostly water with additives. Water is heavy and bulky. Packaging costs more then the product inside. Transport with labor and fuel coats the most.

    If you drink fizzy stuff on the regular, SodaStream is your friend. Here’s a breakdown of the costs, although I haven’t verified it personally:

    Also, by buying a SodaStream you will be supporting the dreaded Zionist entity, so Greta Thunberg will hate you, which is a plus. And by not wasting precious resources on packaging, you will be saving Gaia, which will make Greta love you. The resulting cognitive dissonance may cause her head to explode, so wins all around.

    I hear/read things like this and my decision to dive through the local (residential college) dumpsters is validated once again. Students are incredibly wasteful creatures, and at the end of the semester I harvest all kind of shelf-stable, air-tight-sealed, and/or frozen solid foodstuffs (not to mention all the non-food consumables they toss: soap, shampoo, toilet paper, school supplies, clothes, cast-iron skillets, etc).
