Notes (Include any important notes from brew day until tasting)

mashed in at 153. cool day plus brewing without helper caused a slightly lower strike than anticipated. 1st runnings SG 1.090 a bit of sweetness left in grains after batch sparging. probably not as efficient as could have been with fly sparging, but got closer to expected recipe after I added .5 lbs table sugar to boost OG. Pitched yeast too warm by accident: about 92 degrees. Luckily, it started fermenting by morning. Got it cooled to about 65F to start, then warmed up to about 70F after 3 days to finish fermenting. Decided to add grapefruit zest to the dry hop. 3 zest soaked in 4 oz of vodka for 4 days, then added to muslin bag with 1 oz. cascade hops to dry hop for 5 days.

You wanted an OG of 1.070. It looks like it will be under.

Tasting Notes (3)

Tasted on 10/15/2016 by mpt2222

Notes:

just about all the grapefruit flavor has dissipated. It's now a solid IPA. Smooth caramel start with dry finish. There is a hint of citrus aroma and flavor, but not anymore than a typical IPA which uses this recipe's hops bill.

Tasted on 6/4/2016 by mpt2222

Notes:

6.4 ABV : tasted a sample as bottled. Very cloudy still, nice citrus flavors come through but not a shandy by any means. Definitely a dryer, not overly-bittered IPA, but the addition of grapefruit adds just a bit of aroma without overpowering. Will need at least 3 weeks of bottle conditioning to clear up and balance out to get a final judgment.

Notes:

Grapefruit and dry hops added. Fg at 1.004. great tasting ipa even without the grapefruit or dry hop.
