Do they use fish somewhere in the process for making cask ale beer?

Question

Rumours that they grind down fish bones for the fermentation process but never been too sure how true these rumours are.

Answer 1

Yes. It's not fish bones, however. It is made from the swim bladder of fish and is called finings or sometimes isinglass, though it is NOT the same as the chemical which used to be used for preserving eggs .

"Finings (the term is a mass noun rather than a plural) is a substance used to aid the clearing of beer, particularly cask ale.

One of the defining characteristics of real ale is that it is not filtered or pasteurised, so that the live yeast remains in the container from which it is served. This allows secondary fermentation to continue and more complex flavours to develop. Actually drinking this yeast, however, would be somewhat unpleasant, and so it is necessary to gradually remove it from the beer before it can be served. This is the purpose of finings.

Finings is a thick liquid, usually made from the swim bladders of fish although alternatives exist. Around a pint per 9-gallon firkin is added to the beer, invariably these days at the brewery when the beer is racked into the cask. The finings will begin to act on the beer immediately, but the movement associated with transport will ensure that the yeast remains mixed throughout the cask. Once the cask is placed on the stillage or serving position, vibration and movement will be avoided and the cask can begin to clear." (Wikipedia, of course!)

Certainly in home brewing, the use of eggshells and egg white are sometimes recommended for doing this.

Answer 2

definite you may want to assert that beers are secure for vegetarians. in straightforward words some beer agencies use an ingrediant said as isnglass which a kind of a gelatin that come from a particular fish. even if it does not stay contained in the beer. it really is used as a finning adgent. this signifies that it really is extra to the beer to get each and every of the nice particules to settle out of the beer. Then the sparkling beer is taken off of this contract on the bottom of the tank or barrel. The stuff of the bottome of the tank the position the Isnglass isn't touched at the same time as the beer is bumped off. even if if this nonetheless bothers you then you could seem for a lager that has both been filterd or a lager it truly is bottle fermented. those received't contain the fish byproducts. for my section you'll have not some thing to stress about. the fish product heavily isn't contained in the top. also on your information the top of the beer is actual an air/beer blend. it really is extremely simular in structure to whipped cream. the top in straightforward words looks at the same time as beer is poured from a preasurized source. which contain a tap/keg or a bottle.

Answer 3

I've heard of a type of seaweed used as a clarifier. It reduces the cloudness in beer. Sometimes homebrewers use it.

Answer 4

Isinglass is used in the production of Guinness.

Answer 5

It's true - it's called isinglass (I think) and the brewery industry use it to produce clear beer (lager etc).

Answer 6

That's hysterical...and you believe that???

I used to brew my own ales...never used ground fishbone,,,they always tasted fine without it.

If someone out there believes it...i wanna see the recipe!

I don't believe its true
