A day in the life of a brewing intern 

Some mash tuns have them but they cost MUCH more than the ones without them. Here's an analogy. Say you're building a 2 story house, do you pony up the extra cash to install an escalator or just build a set of steps......sometimes you'll sacrifice 'ease' for the sake of a cheaper 'price'

He ain't gonna answer u lol

Just for knocking that foam down so the sparge arm doesn't get too sticky.

Yes, the guy who has to stir it is highly agitated.

no way but it is true. bewing a brewer means is more like being a janitor that sometimes makes beer

@@Jaguargamingtemple yes, I know. I do it for a living.

I agree that the music is terrible. Just a guess but they probably assumed that the only people watching this video are at least homebrewers whom basically already know. The large tub with the grain in it is a "mash tun" in which the brewer steeps grain in hot water to convert starches into sugars & then extract them. Once the liquid (now called "wort") is moved into the "boil kettle" you have to remove the spent grain & clean the equipment. The green rabbit food looking stuff he was measuring out are "hops" which are added to the boiling wort to add bitterness to balance out the sweetness & is a natural preservative. When he had the hoses hooked up, he was taking the wort through a cooling device & into the fermenting vessel. Hope this info helps.

Americans go by gallons/ barrels

Looks like a 20 HL system. Which are 2,000 liters

That way is more common than you might think.

It's sugary barley water/tea. A hazmat suit is not needed.
