Is there a big difference? The online wholesaler that I'm ordering from only has Pale, Amber and Dark DME and one of the recipes I'm planning to brew calls for Light DME. Will Pale suffice?? (I don't have many other options)
Pale = light. It's possible that one brand's light is slightly darker than another, but they'll work more or less the same.
Cool. The other option they now have is Pilsen DME. It looks light but I'm guessing by the name that it would be more for Pilsner style beers?
Pilsen would be even lighter. It could be used for beers other than Pilsener, and maybe isn't a bad second choice. Belgian pales often use pilsener malt profiles so could use the pilsen DME.
