I am a big fan of ginger ale and ginger beer and ginger tea...ginger biscuits..... This version of ginger beer is a bit fizzy because it is lacto-fermented using whey. It is full of natural ingredients and probiotics. It is very easy to make and lasts for a while in the fridge. You can add some homemade natural sugar syrup or stevia if it is not sweet enough to your taste.
The recipe is from Nourishing Traditions, and I found it on one of my favourite websites, The Nourishing Cook.
You will need:
3/4 cup fresh ginger, peeled and chopped/grated
1/2 cup fresh lime juice
1/4-1/2 cup Rapadura (I used demerara because Rapadura is hard to find here in the UK)
1/4 cup whey
2 teaspoons sea salt
2 quarts filtered water
Mix all of the ingredients together and place in a 2 quart jar, leaving an inch of room at the top. Cover and allow to ferment on your countertop for 2-3 days. Store in the fridge. According to Nourishing Traditions you can add some fizzy water to serve. It is meant to be used slightly warm and consumed in small quantities at a time. It will keep in the fridge for several months.
There are loads of other, very similar recipes available online. There is one on Instructables.com which makes one quart if you feel that you want to make a smaller batch for your first efforts. It uses honey, but needs 3-7 days to ferment. This could produce too much CO2, so might need to be opened every couple of days. And there are several recipes out there which do not require whey, which would be handy if you don't have any on hand.
