I was sure I'd seen this on the SW site but can't find it tonight. It has only 20 kcal per 100 ml as opposed to 39 for the ordinary standard sweetened variety and the same amount of calcium, so it looks to me that you should be able to have twice as much, which is what I could have sworn I saw earlier in the week. Strange. Has anyone else seen it on the site? It's delicious, sweet and thick and creamy, I don't understand how it can be so low in calories.
