I bought bottles of kefir and some of their fermented juices I’ve had them before all of it is wonderful such high quality produce . I mix it with frozen berries me and my wife both in our sixties have a glass every morning. Great for the tum I also bought some sourdough starter I’ve made sourdough before made my own starter before but this stuff is special it really does ferment quickly you can tell it’s high quality. Only problem is I’m running out of flour. The U.K. flour store is empty Even amazon have ran out Never mind the starter will keep in the fridge long enough Get online get yourself some of freshly fermented produce delivered it’s always packed superbly well, you won’t regret it ,your body will thank you
