    So I brewed a full 23 L batch of my Golden Ale and split it into four fermenters at 5 L in each fermenter, leaving the last 3 L as losses. My starting gravity was 1.051, two points over my predicted gravity, and I pitched 1 sachet of yeast into each fermenter.

    On Day One the gravities read;

    M36 Liberty Bell - 1.046 (5 point drop)
    M31 Belgian Tripel - 1.037 (14 point drop)
    M47 Belgian Abbey - 1.045 (6 point drop)
    M15 Empire Ale - 1.028 (23 point drop)

    I took another reading after four days and made some notes about the taste of the beer. The gravities were;

    M36 Liberty Bell - 1.011 (40 point drop) - still very sweet tasting
    M31 Belgian Tripel - 1.007 (44 point drop) - very estery/banana flavour
    M47 Belgian Abbey - 1.013 (38 point drop) - smoother (less bitter than Tripel) but still estery
    M15 Empire Ale - 1.018 (33 point drop) - Best hop aroma, most like a classic golden ale

    Each of the samples was pleasant in it's own way but completely different from the other samples. I was very impressed by just how different the yeasts were making the beer.

    My final gravity was only slightly different from my Day Four reading so I bottled my beer. My tasting notes after one and a half weeks in the bottle are below (a little soon to drink but I was eager to see what the yeasts had contributed);

    M36 Liberty Bell - 1.009 (42 point drop, 5.5% ABV, 82% apparent attenuation) - This version of the Golden Ale was the clearest of all the different beers with a nice, mellow bitterness and a tasty malt character though there was some diacetyl present but if I'd left this in the bottle longer this would be a very nice, drinkable golden ale.

    M31 Belgian Tripel - 1.004 (47 point drop, 6.2% ABV, 92% apparent attenuation) - a lot of banana and clove character on the nose which was very nice. The taste was extremely dry, with my notes reading almost 'brett' level dryness. This was a really interesting version of the beer and I'd love to do some higher alcohol Belgian ales with this in the future.

    M47 Belgian Abbey - 1.009 (42 point drop, 5.5% ABV, 82% apparent attenuation) - A slightly 'yeasty' smell but I described this as a good example of a 'Belgian' golden ale. It was easily drinkable with nice but not overpowering yeast esters. If I did this again I'd probably increase the hops (but in this instance I didn't want them to interfere with the yeast character).

    M15 Empire Ale - 1.017 (34 point drop, 4.5% ABV, 66% apparent attenuation) - The Empire Ale continued to have the best hop aroma of all of them and despite the high finishing gravity the beer didn't taste cloying. A sessionable ale though, I could definitely see this yeast strain working better in something like a sweet stout.
