Café bombón was made popular in Valencia, Spain, and spread gradually to the rest of the country. It might have been re-created and modified to suit European tastebuds as in many parts of Asia such as Malaysia, Thailand and Singapore the same recipe for coffee which is called "Kopi Susu Panas" (Malaysia) or "Gafeh Rorn" [lit: hot coffee] (Thailand) has already been around for decades and is very popular in "mamak" stalls and "kopitiams" in Malaysia. A café bombón, however, uses espresso served with sweetened condensed milk in a 1:1 ratio whereas the Asian version uses ground coffee and sweetened condensed milk at the same ratio. On the Canary Islands a variety named "Café Proprio" or "Largo Condensada" is served using the same amount of condensed milk but a "café largo" or espresso lungo. For café bombón, the condensed milk is added to the espresso. For visual effect, a glass is used, and the condensed milk is added slowly to sink underneath the coffee and create two separate bands of contrasting colour – though these layers are customarily stirred together before consumption. Some establishments merely serve an espresso with a sachet of condensed milk for patrons to make themselves.
Some health benefits of coffee come from the beverage's caffeine content and not necessarily from the coffee itself. For example, the review of studies published in Australian & New Zealand Journal of Psychiatry determined there was also a nonlinear association between caffeine and a lower risk of depression, in addition to the link with coffee itself. Caffeine, a stimulant, also has a beneficial effect on athletic performance, with research published in 2016 in the Journal of Sports Science determining that dosing with caffeine prior to physical activity increased "vigor" and decreased fatigue. To use this to your benefit before working out, drink a cup of black coffee about 30 to 45 minutes before you begin exercising.
