Yesterday I posted a thread on this, but it appears as though it did not appear.
First off, my name is John and I am new here. I am happy to have a source to learn about brewing. I have been brewing all grain for 6 months and have been learning a ton. I am looking forward to continue learning and contribution to the knowledge bank once I know what the hell I am doing
My main interest is brewing authentic british style ales. I have been reading, researching and trying different methods to emulate a true british style beer. As I have found you can get the exact grain profile, hops and yeast and still not get an authentic English style beer. I have several theories on what gives british beers their unique flavor, but have not proven those theories yet. First off I will share the facts that I know for sure that define the recipe of a true british beer.
1. Top cropping british yeast strains are a must to emulate a true ale. Not much else to add here.
2. Open fermentation. This is often scary to try on a homebrew scale. I have experimented by splitting 10 gallon batches into two 5 gallon batches and open fermented one and close fermented the other. The flavor differences were quite noticeable. From what I have found the three main benefits of open fermentation are: easy yeast harvesting, better oxidation of the yeast during fermentation and higher ester content.
A note on open fermentation: The key to safely open ferment beer is to keep the fermenter closed until high krausen. Once the top is off check the beer daily. As soon as the krausen drops immediately rack to secondary. Otherwise the wort is open to all sorts of bad things that can ruin a batch.
Now, in addition to the above factors I would like to discuss fermenters. Their are several different types of open fermenters used in England. The Burton union, Yorkshire Square and the simple open top fermenter. The one thing I know for sure is all of the british open fermenters recirculate wort from the bottom and spray over the top of the wort, minus the burton union. This is to rouse the yeast and rotate still active yeast to the top. This also oxidizes the beer which allows the fermentation to be more active and finish quicker.
Now here is where my theories start. It is my theory that the recirculating and oxidizing of the wort lends certain flavors that cannot be emulated without recirculating. I have not proven this yet, but I am working on a way to do this so that I can prove this.
The other thing I would like to discuss is boil length. I have found several English recipes citing 90 minute boil times instead of 60 minutes. It is possible that the extended boil time crystalizes some of the sugars and turns some sugars into non-fermentable sugars that would lend certain flavors otherwise difficult to emulate. I am not 100% sure what the difference that this will make, but I intend on trying this and seeing what difference this makes.
I am experimenting with these theories in between brewing traditional beer recipes knowing that the risk of spoilage or other contamination is fairly high when experimenting. So I accept the risk when performing these and am aware of the dangers.
Anyways, some of these theories may be far fetched and may not make any difference, but any input on this from the more knowledgeable would be appreciated. Hopefully this would be a good jumping off point for discussion on the matter.
