Campden and asorbic acid

[BeerWolf]

Hi all,
Anyone with experience of using Campden tablets and asorbic acid to deal with oxidation? If so, how much would be suitable for 25 liters new england pale ale?

While I don’t use Campden for oxidation, others have posted in the past as using one whole tablet for 5 gallons, added at transfer. I think a tablet is a gram?

I use 1 tablet of potassium meta-bisulfite (.55 grams) when dry hopping and again when clearing with finings (Cold IPA). I don't use ascorbic acid, but my understanding of it is that it works best in tandem with PMB. It's not a silver bullet when it comes to oxidation, but it can help.

The most I dose is 1.1 grams per 25 liters, I'm not comfortable going over that.

I assume you crush it?

I always crush the tablet. One can also dissolve it in liquid before adding it in.
