Drinking cold brew coffee with no kosher certification

Hi - there is a business in Israel with no kosher certification (just vegan friendly) that produces cold brew coffee. During the process the coffee beans are left to brew/soak in cold filtered water for 12-24 hours, after which they add milk/sugar and bottle it. They have a range of plain bean coffees, and a range of coffee with added flavors. Would it be permissible to buy and drink this coffee? Thanks

ב"ה Shalom It is very important that such a question is asked and no assumption is made before looking into the issue. While pure coffee itself poses no kashrut issues, once any food is processed it needs to be looked into and certified as kosher. There are many things along the way which much be examined, the utensils, milk, additives, flavors and more. Therefore, I suggest that you request this business to apply for proper Kosher certification. Then you can enjoy your coffee without any doubts. All the best
