Hi Jackie, I know it was a long time ago, but do you still have any horseradish in Launceston ? I am in Beaconsfield and would love to grow some so I can make Fire Water with it. Donna.

I grow my hradish in deep pots and after harvesting and grating to preserve with AC vinegar etc it turned out very, very mild?? Not at all hot as I was expecting? Any idea's why?

Hi, if you want your horseradish to be hot, leave it for 2 years in the ground - the older it is the hotter it gets. It does become woody so grating it is a problem. Back in Russia we'd leave the root over winter and in spring it would regrow, then at the end of season its harvested. I'm not sure it would work in Australia unless where you live winter is frosty.

Thank you Peter for your suggestion, I have not harvested my horseradish last autumn / winter as I still had jars preserved from the previous year..So it will suit my pantry very well to harvest in the 2nd year at the end of this year. Thanx

No problem! Please let us all know how they turn out!Just a word of caution - protect your eyes when grating old horseradish - it will burn your eyes. Use swimming goggles. I know people who didn't realize this until it was too late - they got a chemical burn, took a week to recover. Cheers!

Apparently it depends on when you add the vinegar for the degree of hotness. The recipe I found on the net said vitamize and then add the vinegar at the very end for maximum bite. Mine made this way was very spicey.
