I wonder what people think about this.
In my opinion I think that every beer should be serve in 0.5 liter (or 16 oz).
Most of the beer sold in US is sold in 12 oz bottles.
To my liking one beer is not enough and two beers are too much.
What would people think if they found their favorite beer in 0.5 (16.7 oz) four packs instead of 12 oz six packs.
IMO two beers is generally not too much, but it sounds like a good way to trick me into paying the same price for 64 oz of beer instead of 72 oz. 
12oz beers give ya enough room for a good pour and stick your nose into the glass to get a good sniff. Are there bigger “pint” glasses for 0.5 L beers available in Europe???
If you’re bottling, bigger bottles are better… I like the 22oz (except for when I’m drinking the whole thing myself… the 2nd pint can get a little warm).
You don’t stick the second pint in the fridge? I pour off the whole bottle into two glasses, one goes in the fridge the other I drink.
The question is what would you think of it if you would see it in the store?
I wonder if beer consumers would be receptive to alternative packaging.
I do bottle in both sizes 12 oz as well as 0.5 liters.
I don’t like the half liters for bottle conditioned beer. I gave away most of mine to a new brewer.
Delete this and don’t ever say it out loud…They are listening…and my wallet is wafer thin… 
Not really for me - I tend to buy one bottle at a time anyway, so I would likely break the 4-pack anyway. There’s no discount in buying 6 over 1 anyway, at least not where I shop for beer. So I’ll pretty much try it no matter what size bottle it comes in.
Yes, the UK pint is larger than .5 l
In the UK the majority of ‘real ales’, bottle conditioned an otherwise, tend to come in .5 l bottles. There is an instant calculation that the majority of British drinkers seem to be able to perform, which involves working out your beer bang for your buck. The value for money is better on a .5 over a 12oz almost every time in terms of quantity (though not necessarily quality)
For me, it would depend on the beer style. For Euro styles, the .5l would be great. For an IIPA or BW, not so much.
I have always believed that beer should be sold in 16oz servings, but I think that you might have a hard time convincing consumers to switch to 4 packs. I imagine that most people would look at the bottle quantity and feel like they are getting shorted 2 beers rather than doing a quick calculation on oz per dollar.
And think about how ingrained the 6 pack is in our culture.
Would you now call it the tall holiday 3 pack?
Would Black Flag have to re-write Six Pack?
Would Country music as a genre be able to make the switch from a long neck six pack to a longer neck four?
Can you still refer to your abs as a six pack? (haha)
i remember the old shclitz malt liquor 6 pack 16 ounce cans.
we would stop and get our “rack of bull pounders” now that is living.
I remember bringing back a 4 pack of Andechs Doppelbock Dunkel for a friend some years ago, in 0.5L bottles.
You need to go to Germany and do market research.
I prefer the twelve ounce packaging, generally if it is a sixteen ounce serving my wife and I might split it between two ten ounce glasses.
This is another reason I like kegging (as a homebrewer, many times I give myself a 8-10 ounce pour as one or two of those are plenty for an average evening.
I bottle my batches half in .5L and half in 12oz bottles. The .5L are swingtops so they’re for my drinking pleasure at home. For away stuff, I generally use the 12oz’ers since they’re a lot easier to replace should the need arise.
I quite often do buy them. I agree its just the right size for an evening beer and great for sharing with the wife over supper (while the kids are still up).
The stuff I bottle in 12 oz bottles I usually give away.
In Minnesota, Surly sell their beer in fourpacks of 16 ozers, and they do pretty well.
Thank you for your response.
It wouldn’t work in the real world.
It’s a marketing psychology thing.
Remember the Miller pony in an 8 pack? Sold like crazy. Folks don’t consider the quantity (at least non-homebrewers 8) ) ,just the count of the containers.
4 bottles < 6 bottles regardless or the total ounces.
Well, as they say “median intelligence isn’t that smart, and half of the people are dumber than that”.
