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.
