Is this cream of tartar aluminium free?

Dear friend, Our cream of tartar is aluminium free. It is a 100% natural product that comes from grapes. Best regards, Castello since 1907 team.

Your cream of tartar says 79.3g carbohydrates per 100g, other products say they are 62g and Google says cream of tartar is 62g, why the difference?

For your information, we are the main manufacturers of the world of Cream of Tartar and our product is 100% natural, if you have any doubts please do not hesitate to contact us. Best regards Castelló Since 1907

How do you source it? Is it a product made from fermented grapes? Pls let me know.

That's correct. It is a product 100% made from fermented grapes.

As it’s a large jar i was wondering how far away the best before date was? thanks

Hi Laura, It has a shelf date of 3 years, but as it is as well a natural preservative, if kept in a cool and dry place, you can use it beyond its shelf date, mainly because it does not lose properties. We maintain at the factory 1 lot of cream of tartar from 1998 and we keep analyzing it every year and as it is kept in a cool and dry place, it could also be consumed without problems. Of course, we do not sell this lot from 1998 and it is kept in order to analyze it every year and understand how it keeps its properties. Hope this can help.
