FAQ

Will the yeast give off light?

No. The yeast are fluorescent not bioluminescent. They will glow under a "black" light or when using the glasses and blue light provided. More information on fluorescence can be found at https://en.wikipedia.org/wiki/Fluorescence

 

Will my beer fluoresce?

The beer itself doesn't fluoresce the yeast do so your beer will not fluoresce except with yeast in it. When the alcohol is fermenting you will see fluorescent yeast throughout. Usually after a cold crash the yeast will still fluoresce but will be on the bottom of the bottle.

 

I added the yeast to my to my fermentation and it doesn't fluoresce. Why?

To make sure the yeast are comfortable and happy it is suggested that you grow up a few starter cultures. The fermentation in the picture on this item was taken after growing up four 25mL yeast starters and then adding them to a 1L fermentation. The better you take care of your yeast the better they will glow. Don't give them too much sugar and make sure they have proper nutrients. 

 

Do the yeast need selective agents to keep the plasmid?

We have found that the yeast will hold onto the GFP plasmid even in absence of selective agents.
