Note #8: "Who drinks beer below 10 °C anyway?"

10c = 50F and this got me curious at which temperature the mountains turn blue on the Coors can [1]. Coors has apparently determined that 40F-48F (4.44C - 8.88C) is the perfect temperature for their swill. https://www.youtube.com/watch?v=dM3USopPZoA

For beers like Coors I find the colder the better. You taste it less.

I suspect that the glass for Pauwel Kwak is more or less ideal, based on this paper. Only beer glass I’ve ever known (apart from yards) that can’t stand up on its own. Seemingly appropriate, given what a few Kwaks will do to you. https://www.google.com/imgres?imgurl=http://belgiancraftbeer...

I was a bit disappointed that the kwak glass didn't make an appearance here. Although I suppose the treatment of the thick bottom as being better insulating wins out over volume efficiency.

IDK, the spherical base minimises surface area for volume, and the narrow where it joins the sphere and then spreading neck inhibits circulation between the top and bottom portions of the vessel.

Can you settle a dispute for me? A friend and I were debating (and placed a bet!) on whether one is to drink by holding the wood handle or by removing the glass from the stand. I find a lot of disagreement about it, but no official source.

I’ve only ever taken the glass from the stand - holding the whole apparatus feels unworldly.

Also, as a gentlemanly rule, once you pick it up, you do not put it down until it’s empty.

Earlier quoted context omitted.

I always thought of that shape as the Luminarc working glass design. Which I assumed came from the Duralex Picardie design. Are these all related, and if so how and in what order of lineage? (I think the year of design goes 48 luminarc, 54 picardie, 56 nadir)

https://pt.wikipedia.org/wiki/Copo_americano Looks like it's adapted from the US model of a popular Soviet glass.

Interesting. https://en.wikipedia.org/wiki/Faceted_glass

> The Nadir Figueiredo glass […] maintains the beer cold through the most primitive of the processes: due to its low capacity, the beer is consumed so quickly that it has no time to get warm. Brilliant! I want to add a trick that I learned from my father in law, who keeps his heavy-bottom beer glasses in the freezer.

But it means you need more frequent attention from the server or bartender, which the pub owner won't like because it means hiring more servers. That's why the ridiculously enormous beer glasses (20+ ounces) are so common. Good for the profitability of the bar, but you end up drinking half of it warm.

More frequent attention is a solved problem: a server walks around with a tray of filled glasses and always replaces empty glasses, except if they are covered. That way, the communication overhead is reduced, and a roundtrip per table back to the bar is no longer required. With that, the number of servers can also be kept to an efficient minimum.

Obviously, this works only if a very small selection of beverages are served.

In addition to the interesting work done on heat transfer, i believe an important factor is the vertical height to base ratio. This would be simple proxy for the ease of tipping over. Some of the glasses considered are very tall in relation to their base diameter and expand in diameter towards the top of the glasses.

I’d go for the imperial pint glass, a very familiar shape and weight for me. Sample of 1 and I do live in Scotland where the ambient temperature rarely causes warming of the beer.

They were talking about frost build-up from freezing a large stein glass. If any frost gets onto the inner surface of a glass, it creates nucleation points.

But wouldn't that frost melt immediately upon contact with the (relatively) warmer beer?

Maybe foam creation is also immediate, and wins that race to some extent?

Any experienced Stein drinker will attest that the solution is to drink it at the same pace as you would a smaller beverage receptacle.

Down in one?

A fraternity I rushed managed to execute a very similar strategy on a two-four of Natural Light.

Back in college when I had a kegerator, we kept the large glass steins in the freezer. The problem with that is the beer would freeze slightly and you end up with little bits of ice floating in your beer. Plus your hands get cold, which is a bummer in the winter in Montana.

This calls for something a bit like the ridiculous fridge innovation: the butter warmer.

‘In this environment we are paying to cool, let’s have a warming element.’
