    Newbie question: specific gravity and secondary fermentation

    I've decided to take the plunge during the lockdown. I recently started a Cru International Australian Cabernet Sauvignon wine kit with the Master Vintner kit from Midwest Supplies. I am on day 15 of my kit. Unfortunately, the hydrometer was missing from my kit, and I'm yet to request a...

    Hydrometer readings with whole fruit

    I am thinking about making my first batch of wine. I have a bunch of blueberries frozen that I can thaw out and use. I just got a two gallon fermenting bucket. I was figuring I would find a recipe I liked and fill that bucket. I will probably try to put the thawed blueberries into a paint...

    SG doesn't drop for several days. Is fermentation done?

    So my beers (two 11 liter batches) have been brewing for 12 days now and the recipe suggests a SG value between 1.008 and 1.014 before bottling, and that it should be achieved in 8-10 days. I checked the values first on day 8, then 10 and 12 and they haven't dropped (maybe VERY little). Is...

    SG for newbies

    OK, I am confused again, despite having acquired some books. I siphoned my elderberry wine from concentrate at an SG of 0.990 the the other day according to the recipe; because I didn't realize that fermentation had stopped naturally, I added a packet of Montrachet, which quickly fell to the...

    what is good advice in sugar per gallon content?

    I have a kegging system and have decided to make an easy root beer recipe for a company event. It is the Gnome extract I am using and want to use light brown sugar and honey as the sugar base. First, is that a good choice....approximately half honey, half sugar??? Second, sine I am not naturally...

    Time to repitch?

    Long story short I ordered yeast (WLP029) from Homebrew Supply, and FedEx took the scenic route to get here. After 5 days I got my yeast. The cold pack, and vial were very warm. But I decided to give it a shot anyway. Made a starter, pitched it in, here we are three, and a half days later...

    Converting SG(15/15) to SG(20/20)

    None of the SG hydrometers I have found are calibrated to 20C. I have been thinking about a method or methods to do this conversion, but can't try them without, for example, both gravities for a 10P solution. The more complicated nerdy method starts with equality of mass of extract (wex): wex...

    Calculating %ABV Without the Initial Specific Gravity

    One likes to know the final alcohol content after making a batch of wine. Typically, one can calculate this from the initial and final specific gravity. The initial specific gravity can be measured directly or from the Brix number from index of refraction measurement. %...

    Interpreting SG and sugar content

    With the help of this forum and other resources, I've managed to ferment a few ciders and meads with some success. I feel comfortable referencing before and after measurements of specific gravity to estimate alcohol content, but I had a follow up question on interpreting that value. Would it...

    first batch in a 15gallon conical w/ no bubbles

    i just bought a 15 gal minibrew conical of craigslist. i wanted to try something simple, so i made a 10 gal recipe of english bitter. i has set there for 2 1/2 day without a single bubble coming out the blowtube. my original gravity was 1.050 @ around 100f and today it was 1.020 at 65f. there...
