This is a tricky one.
Until earlier this year, Hansen’s had only one UK stockist: Somerset based Strattons tel: 01749 838 690. Strattons come in for a fair bit of criticism over service – it can take a long time for them to get hold of the starter, so if you do order from Strattons, be prepared for delays. They do, however, have access to a wide range fo Hansen’s starters.
There is now another, more reliable stockist: Westcombe Dairy, also based in Somerset, tel: 01749 838033. My contact there is a lovely chap called Tom, who makes traditional cheddar.
