So far all turned out ok and all have produced masses of foam, so to stop spills I add 4 litres of juice and add another ltr. when things have calmed down.
This time I added 200g of Honey (it was set type) I melted this with a bit of juice and chucked it in.
Fermentation off like a rocket but this time no froth at all

Do you think the honey caused this?
BTW Yeast was from a Muntons kit (as were the others)
Cheers
