On a somewhat related topic - I've been researching recipes for my first irish red ale. Reading thru various recipe threads, it seems that the colour of the final beer seems to vary from brewer to brewer given essentially the same recipe. Some saying 'came out a beautiful red/ruby colour' other saying 'meh, came out kinda brown'.
Now obviously there are a lot of variables at play here, not least the malt/maltster chosen for the colour malts, but it got me thinking - could oxidation be a variable?
Does a lower DO brewhouse produce a better red colour? Old red wines go a sort of red brick colour as they age don't they? Any thoughts?
