So what exactly are they?

Kombucha is fermented tea made with a kombucha starter culture or SCOBY (symbiotic culture of bacteria and yeasts). There are all sorts of names for the culture including mushroom, mother, scoby, fungi and many more. The mixture is allowed to ferment at room temperature for 5 to 30 days. It can be consumed plain or with added flavouring such as fruit, juice or spices. Kombucha contains a number of vitamins (particularly B vitamins) and has a number of health benefits. It contains pro-biotics and as it is fermented lots of lactic acid bacteria.

Water kefir is a probiotic beverage made with water kefir grains. Water kefir grains can be used with sugar water, or coconut water. Water kefir grains harbour a set of bacteria and yeast existing in a symbiotic relationship (this is the same as the Kombucha so is also scientifically termed a SCOBY, the water kefir scoby and the kombucha scoby however contain different bacteria). The term "kefir grains" describes the look of the culture and they can at times be referred to as seeds. They are not seeds in the usual sense and cannot be planted!

Milk kefir is the drink, but Milk kefir grains are the “starter kit” that you use to produce the drink. Kefir originated from parts of Eastern Europe and Southwest Asia. The name is derived from the Turkish word keyif, which means “feeling good” after eating. The Kefir grains are natural symbiotic cultures containing a huge number of natural bacteria that turn the lactose in the milk into lactic acid. So kefir tastes sour like yogurt and it has a thinner consistency so it is more smoothie like.
