Here's an email from Best to my homebrewer friend Jeff who is trying to reach a crimson red color. Pretty interesting.
Thank you for your Email. First of all a few explanations about the Red X:
We developed this malt type to use it with 100% of the malt bill and to get then a red beer. The idea was from the beginning to create a “ready to use” malt to brew beer with a rich red (reddish) colour and a very smooth malty taste. We achieved the realisation of this idea with the successful Red X malt. So you should get the best results (red colour and an optimal taste) if you use 100 % Red X in the malt bill, an extract content of 12,5% Plato (ready boiled wort) and a pH of 4,2-4,5 in the ready beer. If you aim a lower extract content than 12,5% you should use some BEST Melanoidin malt to get the beer a bit darker, if you aim a higher extract content than 12,5% you should adjust with some BEST Pilsen malt (straight proportional ratio). Anyway the ready beer should be as clear as possible. Any remaining turbidity or cloudity is a disadvantage for red colour.
My concrete questions are:
1.) What does the sign # in the malt bill mean?
2.) What was the plato of the ready wort?
3.) Could you send me a picture of the beer?
I am very sure we can solve the issue together and reach your aim of a really red beer,
Kind regards from Heidelberg
