Save yourself some money and learn to drink coffee without any sugar, TG! :D
No, seriously, if you must use sugar and most of the coffee drinkers I know do, I consider raw sugar better over white. Though, at one stage I was giving friends Demarra sugar to put in their coffee, as it was all I had at the time and as I got a favourable response to it, I kept using it for coffees. It has a nice caramel type flavour that actually does complement coffee well.
At the shop, we currently use just the white sugar sticks and Equal as well. Though next order, I am going to be getting the raw sugar sticks as well.
I use it as a bit of a benchmark when out doing the cafe scene. If there is white and raw sugar on offer, I think its a good thing as the cafe has had a bit of a think about how they want their coffee treated. Though I have had good coffee at places that do only offer up white sugar. I guess they figure that if you need to sully their coffee with sugar you can just do it with that!
And I have to laugh at those people who come in to our shop and order a large skim milk cap and then say, can I add three sugars? :o Weve now changed that policy anyway. The customer can now add their own to their takeaway! Saves me the stress of watching a great cup get ruined by so much sweetness! ;)
