Best regards Castelló Since 1907 **Q: How do you source it? Is it a product made from fermented grapes? Pls let me know.** A: That's correct. It is a product 100% made from fermented grapes. **Q: As it’s a large jar i was wondering how far away the best before date was? thanks** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Crème of Tartar *by C***Y on 5 June 2025* Perfect for making playdoh! ### ⭐⭐⭐⭐⭐ Excellent *by A***. on 28 January 2026* Excellent value for money and really quick delivery 👌 ### ⭐⭐⭐⭐ These arrived on time. 1/2 size to usual quantity. *by L***A on 24 July 2023* This looked a good buy as very hard to find tubs of cream of tartar. These are tiny tubs! The access opening is too small to get any spoon inside. I had to force the whole top off with a sharp knife & twisted it to open. Spilt some as it jerked. It’s very fresh & has a good. shelf life,& works well. ## Frequently Bought Together - Castello since 1907 Premium Cream of Tartar - Food Grade - 100% Natural from Grapes - Natural Substitute for Baking Powder - Gluten Free - Phosphates free - Keto and Paleo - Non-GMO - 800 g - by Amazon Plain Wheat Flour, 1.5kg, Great for for Baking --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/61157860-castello-since-1907-cream-of-tartar-800-g-natural-baking](https://www.desertcart.hr/products/61157860-castello-since-1907-cream-of-tartar-800-g-natural-baking) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-06*
