I don't have that either...though that's actually in my cart on morebeer. Seems my RO system is either on its way out, or never really removed chloramines. Last beer has a band-aid/plastic nastiness that I'm attributing to that.
But again, that won't be here for the weekend. I'm brewing with distilled this time around.
And again, I'm not trying to recreate a modern German brewery. Post-fermentation I'll be taking great efforts to prevent oxidation, trying to see if pre-boiling alone would do anything.
