I sampled my first bottle of my tofu-enhanced GF beer. It was very light in body, as I kind of expected. It required a fairly vigorous pour to get a nice head on the beer, but the bubbles were small and dense and a thin layer of head lasted throughout the entire glass, and even a bit of lacing. The beer itself was very quaffable, but there was very little rhubarb flavour other than a bit of tartness. I could detect no taste or odor of tofu - in fact, I almost forgot that it had tofu in it until the last few ounces.
The beer itself was pretty straight up with sorghum syrup and I added a bit of Roger's syrup to boost the alcohol. I added some roasted buckwheat and quinoa for colouring (obviously not roasted enough), and lightly hopped. I threw in about 12 oz. of mashed up medium tofu for about 20 min of the boil. Most of it remained in rather disgusting chunks and I ran the wort through a sanitized sieve before pitching the yeast. Any larger chunks remaining have settled out in fermentation. After about 2 weeks, I added in about 2.5 lbs. of frozen rhubarb. At the end, I have a very clear, dry and light coloured beer with decent head.
If I were to try my hand at it again, I would probably:
1. Leave out the quinoa and buckwheat, as I don't think they add much to the beer.
2. Either leave out the fruit, or try something different like apricots or sour cherries.
3. Work on finding some way to add some colour to the beer.
4. Grow a GF starter for a hefeweizen strain to give the beer more hefe yeast character.
