They differ in taste and quality quite widely, and there seems to be no definitive source of information ( that I can find ) , although the 'net is flooded with how-to's which all start with ' get your grains'.Is there any way of storing the grains, say if we were on holiday for a week or more?
Also, does anyone have any recommendations as to where is best to buy good grains? Do they differ much?
When you have the ones you're happy with you can put them in a clean jar with a small amount of good milk then straight in the fridge where they'll go to sleep and be good for 2-3 weeks; when you change the milk, leave in ambient temp. and 24 hrs later they're back to work.
