I think that a majority of the Teachatters who frequent the Black Tea forum, certainly the ones that buy the Premium teas would drink it neat. But there are many on the boards, some in the Black Tea, but particularly those that frequent the forums for Flavoured Tea, Herbal Tea and Other Tea that use a variety of sweeteners, types of sugar, types of honey, alternative sweetners such as Stevia.
Doing a search using different combinations of Sugar, Sweetener, Honey, Milk, Cream, Additives etc - will bring up a whole host of topics where these issues have been dealt with before. If you get insufficient response on this topic, you may consider doing a search [but then you have to sift through the posts it produces to find relevant ones]
I did a sample search and found this Topic Of The day which might be worth reading.http://www.teachat.com/viewtopic.php?f=31&t=14898&hilit=+tea+milk+sugar
I would not buy a premium Black Tea and add Milk and Sugar, though I might buy an Irish Breakfast Tea or English Breakfast tea for that purpose.
Eventually you may come to prefer Black Tea without, to achieve that end (enjoyably), over time as you move up the quality scale of Black Tea decrease the amount of Milk* and Sugar and see if a) it is still enjoyable, and b) you are starting to appreciate, more and more, the qualities of the leaf itself that make it worth paying the extra money on these esteemed teas.
*Try replacing cream with milk, then lower fat and finally no fat milk before you omit the milk altogether.
A quick search of the Black Tea Forum for "No Milk" shows this topichttp://www.teachat.com/viewtopic.php?f=1&t=11877&hilit=+No+Milk+
Part of the fun for many Teachatters is trying things out, and exploring the world of tea.
You could always try a black tea sampler from our hosts and see how they turn out!http://www.adagio.com/black/black_sampler.html
