Over the weekend I attempted a brown beef stock for the first time.
I roasted (from frozen) a couple of kilos of beef bones in the oven for an hour or so until they were a deep brown colour all over.
I drained off the fat that had collected in the oven dish, deglazed with water and added this and the bones into a stockpot with an additional 2 litres of water, roughly chopped onions, carrots and celery, a few sprigs of thyme, a couple of bay leaves and a few black peppercorns.
The stock was brought to the boil and then left to simmer for 3 hours over a low heat. When I strained the stock, it was a yellowy tan colour and not the dark brown that I had been hoping for.
What did I do wrong?

The brown color of the stock comes from the cooking method, not the kind of bones, a chicken stock cooked in the "brown stock" method can be as dark as what we expect beef stock to be.
Roasting the bones was a good start; but you also need to brown the vegetables, either with the bones for the last half hour or in a pan on the stovetop.
One of the most important parts of brown stock is to add tomato to the vegetable mix, either finely diced or more often tomato paste. Cooking the tomato to a dark brick red will round out the components needed to make a very dark stock.
Whether you roast all the ingredients together in the oven or separate the vegetables to the stove; deglazing everything as you did helps the flavor, color, and of course makes cleaning the pans easier :)
