    As far as BPA, I don't see it as a problem. The FDA has said it's fine (I think). I don't think it is an issue unless you are heating beer cans. Which is funny, because some ultralight backpackers use old beer cans as lightweight pots to cook their meals while camping. Of course, I think there may be a problem with storing beer in a can for long periods. Glass bottles are probably better for beers that you would put away in a cellar.

    My favorite part about cans: a 6 pack of cans is lighter and more friendly for transporting via bicycle!

    Edit: http://www.npr.org/2012/03/30/149668771/how-much-bpa-exposure-is-dangerous

    That's an interesting link. A study showing that the body doesn't absorb BPA very readily.

    Cans are far more advantageous than bottles for numerous reasons:

    1) Freshness: no air, no light, etc.
    2) Easier to ship: cans are much lighter and have two flat edges allowing them to be shipped in sqaure/rectangular packaging, not the bizarre inefficient trapezoids created by bottles
    3) Ease of recycling: Aluminum MUCH more efficient to recycle than glass and creating a new can out of recycled aluminum uses MUCH less energy

    Now with that said I've had mixed reactions with cans. Some beers tasted delightful and others were not so good (Yes, I poured into a glass). For the ones that didn't taste as good, my guess is that it was likely older, improperly stored, etc. and not the can's fault. Cans really are spectacular for tailgating and smuggling :)

    Here's my questions, does the lining extend all around the inside of the can? Meaning, the underside of the lid thats crimped onto the body of the can (part with the tab-pull)? That seems to not have the same texture feel as the body of the can to me. Also, the scoring of the tab itself and the crevice created by the crimp would be perfect for infections to take hold and thrive.

    If the lid/tab aren't lined properly you'd get the effects of the aluminum impregnating the beer.

    Obviously this is all speculation. IMO glass is fun because its fancier, and can be recycled with about the same energy consumption. Also, glass is less harmful to the environment to make since you don't strip mine for sand...

    Aluminum also has a SUPER low specific heat, so it leaves the beer more susceptible to heat damage...

    No air in a can? Not true. There is essentially no difference in disolved oxygen levels between bottles and cans when run on well maintained lines. And on a poorly maintained line, cans are extremely capable of having very high O2 levels.

    Both recyclable. Which is better for the earth?

    How do you figure glass can be recycled with about the same energy consumption? That's simply incorrect.

    And about the specific heat, I don't really think that matters. If you're holding it up to a flame for a few minutes sure, but if all the beer is sitting in a hot warehouse or in the back of a hot truck for hours/days/weeks everything will be hot regardless of the packaging

    The can lining covers the entire inside of the can. The underside of the lid is also completely covered.

    I was referring to atmospheric air getting in. Minor point, but those caps aren't perfect.

    I imagine bottles have some advantage because of the oxygen fixing caps, but it raises a question: do cans utilize any type of oxygen fixing device? Do they need to?
     
  9. LAD

    LAD Apr 16, 2008 Texas

    Cans do not have any type of oxygen fixers. Most people in the industry would say they are not needed.

    I was wondering about that too, but figured Lucidious was referring to the energy it takes to throw the container into a recycling bin or bring it to a redemption center.
    My understanding is that it takes a lot less energy to recycle aluminum cans on the processing side of the equation, as in after it gets to a recycling center the amount of energy needed to clean and process a can into aluminum that can then be re-used is considerably less than the amount of energy it takes to do the same thing with glass.
    This is the best argument I've heard against using cans in the beer biz—the process of extracting and processing aluminum ore from bauxite deposits is not exactly enviro-friendly. Not that it makes it better, but to be fair the craft beer industry would probably only increase the volume of aluminum extraction by a fraction of what it already is.

    Still, I agree with most environmentally conscious folks that every little bit helps, so when it comes to environmentally-conscious craft beer producers I'm sure it comes down to an equation of "does the amount of energy conserved by the use of aluminum cans outweigh the environmental impact of increased aluminum extraction?"

    But it isn't! With the average can weighing in at less than an ounce and the average glass bottle coming in at 6 ounces. That's alot of extra effort on my part :)

    Mind = blown I just thought about how cans were filled and closed with beer inside and I am drawing a blank...

    Canned IPAs have been drinking great since I started drinking from them 2 years ago

    There is no "could" about this issue any more. Do a quick search and you can find tons of studies...

    Not saying I don't completely ignore them since Ten Fidy and Gordon only come in cans.

    Well as I see it I believe in most cases there is a sort of nostalgia to having beers and aging them in bottles. In most cases it does seem there are some advantages to cans(preserving hops, protecting from sunlight, ect..)But I believe certain beers like Belgian strong ales and Barleywines benefit from bottles due to their potential to continually condition and carbonate in the bottle. I don't know for sure but it may be a bad idea to condition beer in a can. Just another log to the fire...

    Huh? Just because studies show that BPA is poisonous doesn't mean the amount you consume by drinking a can of beer is harmful. The BPA in a beer can "could" harm you, but only if you drank 450 cans in a short amount of time.

    I've never used a heine pot, but I did just make my first beer can alcohol stove the other night. Can't do that with a bottle.

    Long term storage for cans is much better than bottles assuming storage is not too warm. No light struck cans.

    As stated by others here, Cans allow zero light penetration, zero chance of a leak or cantamination. Some claim that the metal can imprint flavor into the beer but from someone who works at a brewery I can assure you the cans we use as well as 99% of cans used on the market now have a plastic lining which would prevent this from happening. I pour all my beer into various kinds of glasswear anyway. I would drink everything in cans if I could!

    Is this a guess? Do you have facts to back up your assertion that long term storage is better for cans than bottles?

    I like cans because of their portability and ability to maintain freshness, but I usually buy bottles because I can put my home brew in them. Also, I usually find bottles more aesthetic and will sometimes hold on to special bottles as momentos. I don't know of many people with a good can collection... except for this guy:
     
  32. Spikester

    Spikester Jul 14, 2007 Oregon

    No. But it stands to reason that the light struck issue would be a no-brainer. Unless you assume that long term storage would somehow affect the taste via can lining. Some folks insist that they can taste aluminum is any canned beer they drink. Not my experience. If the canned beer is sitting in a non-refrigerated (high temp.) warehouse maybe that would be a game changer. The only beer I have had that was sub-par was the Church Key lager that had some sealing issues and had a wide variation in seal quality. Some of those cans were reported to rupture and lose all carbonation. Otherwise a tasty canned beer.

    Personally, I think cans are great. The biggest issue that I have is the cost. According to the brewers that I asked, the cans are currently more labor intensive to package, and therefore, cost more than bottles. Hopefully, eventually, the price will come down to match bottles. Also, even though I shouldn't do it, drinking from the can seems to make them go down much easier.

    Dude, I'm just sayin this stuff ain't great, but what are you gonna do it's there. Probably not that big of a deal. Hence the rest of my post about drinking it anyway.

    The only thing I really worry about is long term aging and what the can/liner could turn into.

    Drink it don't age it, most canned stuff needs to be consumed fresh, hell even Ten Fidy doesn't need aging. IMO most aging is over rated.

    Any thoughts on the new generation of bottle-shaped cans? I just got The Deuce from Oskar Blues which is packaged in what Miller-Coors brags as their innovative "Aluminum Pint." And yes, it's easily re-sealable or rescrewable, and invite you to pour in a glass instead of scraping your lips on the thin edge.

    For large brewers cans are less costly to run. It takes fewer people to run a can line and can line speeds are usually much higher than bottle line speeds.
