Hi all, my name is Ratso and up until two weeks ago it had been 12 years since my last brew. Once an addict, always an addict I suppose.
I decided to do a few small batches (7 litres, about 2G I think) using DME to get back into the swing of things. One thing I have learnt from this great site as I geared up to start brewing again is the idea of late extract additions. I have brewed two batches so far using 1kg (just over 2lb) of DME that comes in 500g packets. Logically enough I decided on starting the boil with one packet of the DME with the other packet getting chucked in at flame-out. I know how much of a pain DME is to stir into hot wort so I decided to mix the late addition DME with cold water first thereby creating a dilute LME which was easy to mix and easy to pour into the wort. However, I used a whisk to mix the DME to the cold water and thinking about it now I might have made a mistake by introducing oxygen to the late addition which is then obviously added to the boiling wort at flame-out.
Have I cocked up my first batch by oxygenating the wort? I understand that HSA isn't such a concern for us HBers these days but by whisking the DME pretty solidly I did create a lot of foam which was then poured into the wort. Fermentation seemed to go fine but will I find 7 litres of malt vinegar when I bottle next week (will then have been three weeks in primary) and should I maybe consider bottling now to try and get a few beers drunk before turning to vinegar.
Yeah, I know the relax mantra but it doesn't feel like I've started brewing again until posting a 'is my batch ruined' thread
