He certainly is and there is a lot of terrific information on his site. Beware of his recipes however, especially the amount of sugar. Always check the SG with your hydrometer and aim for 10-12% for fruit wines.

The recipes there are OK and a good start particularly for out of the box wines. I agree that the fruit content is low and SG is high in most of them. You have to remember though that these recipes are all suited to his taste which is highly subjective.
