Hi, does anybody know who to approach for Aw testing in the UK? Did a quick google, but clearly the results are more geared towards the large commercial users rather than small businesses.
How do the rest of you determine what shelf life to declare on your products?
thanks,
Gracie

If the recipe is:
38% fat content for cream,
Then:
150 grams chocolate
15 grams glucose ...lowers the water activity level (25% of cream)
60 grams cream (2:1 chocolate/cream ratio, white/milk is 2.5:1)
15 grams liquor (20% of cream so 75grams -20% =60 grams cream))
8 grams butter (50% of alcohol)
This is a smaller version of a formula suggested by Peter Greweling of "Chocolate Confections..." This is a good book to have on your shelf. It explains a lot of stuff!!
These chocolates should give you about a 5 week shelf life. Of course, you want to move it alot faster as flavour is much better in the first few weeks of the chocolate's life!!!
