Grape and Granary Brewtan B - 1 oz Bag

I started using this a few years ago in all my brews. I can't remember if it was a Brewing Network podcast or Master Brewers Podcast where I first heard about it, but it seemed like cheap insurance to help avoid premature staling. It's hard to say without doing a blind triangle test, but I do feel like it's lived up to its claim of improving shelf life and reducing chill haze. I've had several "older" light-colored lagers medal in competitions using this product. Fresh beer is always better, but it does seem like this can help extend the shelf life. I use it in the mash and dose with ~1 gram for a 5 gallon batch.
