Aparrently Muntons also make Woodfordes so complaints about either to the above address.
Spoke to guy in Local HBS regarding stuck ferments today, not news to him either, he's had a few complaints (one stuck on him also!) he blames the yeast. (personally I think it's the Malt extract as I've had two stick using Safale 04)
HBS Guy suggested we send our complaints to the above e mail address. he also said he'd complained on behalf of some customers who'd had the same issue but apparently Muntons said first they'd heard of it..... lets not make it the last!
Started a Brupacks kit off today, let's see if this sticks
